e02d37bf55 sound updates for 4.17-rc1
This became a large update.  The changes are scattered widely,
 and majority of them are attributed to ASoC componentization.
 The gitk output made me dizzy, but it's slightly better than
 London tube.
 
 OK, below are some highlights:
 
 - Continued hardening works in ALSA PCM core; most of the
   existing syzkaller reports should have been covered.
 
 - USB-audio got the initial USB Audio Class 3 support, as well
   as UAC2 jack detection support and more DSD-device support.
 
 - ASoC componentization: finally each individual driver was
   converted to components framework, which is more future-proof
   for further works.  Most of conversations were systematic.
 
 - Lots of fixes for Intel Baytrail / Cherrytrail devices with
   Realtek codecs, typically tablets and small PCs.
 
 - Fixes / cleanups for Samsung Odroid systems
 
 - Cleanups in Freescale SSI driver
 
 - New ASoC drivers:
   * AKM AK4458 and AK5558 codecs
   * A few AMD based machine drivers
   * Intel Kabylake machine drivers
   * Maxim MAX9759 codec
   * Motorola CPCAP codec
   * Socionext Uniphier SoCs
   * TI PCM1789 and TDA7419 codecs
 
 - Retirement of Blackfin drivers along with architecture removal.

ac9053d2dc USB/PHY patches for 4.17-rc1
Here is the big set of USB and PHY driver patches for 4.17-rc1.
 
 Lots of USB typeC work happened this round, with code moving from the
 staging directory into the "real" part of the kernel, as well as new
 infrastructure being added to be able to handle the different types of
 "roles" that typeC requires.
 
 There is also the normal huge set of USB gadget controller and driver
 updates, along with XHCI changes, and a raft of other tiny fixes all
 over the USB tree.  And the PHY driver updates are merged in here as
 well as they interacted with the USB drivers in some places.
 
 All of these have been in linux-next for a while with no reported
 issues.

f5a8eb632b arch: remove obsolete architecture ports
This removes the entire architecture code for blackfin, cris, frv, m32r,
 metag, mn10300, score, and tile, including the associated device drivers.
 
 I have been working with the (former) maintainers for each one to ensure
 that my interpretation was right and the code is definitely unused in
 mainline kernels. Many had fond memories of working on the respective
 ports to start with and getting them included in upstream, but also saw
 no point in keeping the port alive without any users.
 
 In the end, it seems that while the eight architectures are extremely
 different, they all suffered the same fate: There was one company
 in charge of an SoC line, a CPU microarchitecture and a software
 ecosystem, which was more costly than licensing newer off-the-shelf
 CPU cores from a third party (typically ARM, MIPS, or RISC-V). It seems
 that all the SoC product lines are still around, but have not used the
 custom CPU architectures for several years at this point. In contrast,
 CPU instruction sets that remain popular and have actively maintained
 kernel ports tend to all be used across multiple licensees.
 
 The removal came out of a discussion that is now documented at
 https://lwn.net/Articles/748074/. Unlike the original plans, I'm not
 marking any ports as deprecated but remove them all at once after I made
 sure that they are all unused. Some architectures (notably tile, mn10300,
 and blackfin) are still being shipped in products with old kernels,
 but those products will never be updated to newer kernel releases.
 
 After this series, we still have a few architectures without mainline
 gcc support:
 
 - unicore32 and hexagon both have very outdated gcc releases, but the
   maintainers promised to work on providing something newer. At least
   in case of hexagon, this will only be llvm, not gcc.
 
 - openrisc, risc-v and nds32 are still in the process of finishing their
   support or getting it added to mainline gcc in the first place.
   They all have patched gcc-7.3 ports that work to some degree, but
   complete upstream support won't happen before gcc-8.1. Csky posted
   their first kernel patch set last week, their situation will be similar.

903d271a3f ASoC: Updates for v4.17
This is a *very* big release for ASoC.  Not much change in the core but
 there s the transition of all the individual drivers over to components
 which is intended to support further core work.  The goal is to make it
 easier to do further core work by removing the need to special case all
 the different driver classes in the core, many of the devices end up
 being used in multiple roles in modern systems.
 
 We also have quite a lot of new drivers added this month of all kinds,
 quite a few for simple devices but also some more advanced ones with
 more substantial code.
 
  - The biggest thing is the huge series from Morimoto-san which
    converted everything over to components.  This is a huge change by
    code volume but was fairly mechanical
  - Many fixes for some of the Realtek based Baytrail systems covering
    both the CODECs and the CPUs, contributed by Hans de Goode.
  - Lots of cleanups for Samsung based Odroid systems from Sylwester
    Nawrocki.
  - The Freescale SSI driver also got a lot of cleanups from Nicolin
    Chen.
  - The Blackfin drivers have been removed as part of the removal of the
    architecture.
  - New drivers for AKM AK4458 and AK5558, several AMD based machines,
    several Intel based machines, Maxim MAX9759, Motorola CPCAP,

6d23ee9caa usb: changes for v4.17 merge window
Quite a lot happened in this cycle, with a total of 95 non-merge
 commits. The most interesting parts are listed below:
 
 Synopsys has been adding better support for USB 3.1 to dwc3. The same
 series also sets g_mass_storage's max speed to SSP.
 
 Roger Quadros (TI) added support for dual-role using the OTG block
 available in some dwc3 implementations, this makes sure that AM437x
 can swap roles in runtime.
 
 We have a new SoC supported in dwc3 now - Amlogic Meson GX - thanks to
 the work of Martin Blumenstingl.
 
 We also have a ton of changes in dwc2 (51% of all changes, in
 fact). The most interesting part there is the support for
 Hibernation (a Synopsys PM feature).
 
 Apart from these, we have our regular set of non-critical fixes all
 over the place.

Merge tag 'usb-for-v4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-testing

Felipe writes:

usb: changes for v4.17 merge window

Quite a lot happened in this cycle, with a total of 95 non-merge
commits. The most interesting parts are listed below:

Synopsys has been adding better support for USB 3.1 to dwc3. The same
series also sets g_mass_storage's max speed to SSP.

Roger Quadros (TI) added support for dual-role using the OTG block
available in some dwc3 implementations, this makes sure that AM437x
can swap roles in runtime.

We have a new SoC supported in dwc3 now - Amlogic Meson GX - thanks to
the work of Martin Blumenstingl.

We also have a ton of changes in dwc2 (51% of all changes, in
fact). The most interesting part there is the support for
Hibernation (a Synopsys PM feature).

Apart from these, we have our regular set of non-critical fixes all
over the place.

21e9b3e931 ALSA: usb-audio: fix uac control query argument
This patch fixes code readability and should have no functional change.

Correct uac control query functions to account for the 1-based indexing
of USB Audio Class control identifiers.

The function parameter, u8 control, should be the
constant defined in audio-v2.h to identify the control to be checked for
readability or writeability.

This patch fixes all callers that had adjusted, and makes explicit
the mapping between audio_feature_info[] array index and the associated
control identifier.

aaeab02ddc usb/gadget: Add an EP dispose() callback for EP lifetime tracking
Some UDC may want to allocate endpoints dynamically, either because
the HW supports an arbitrary large number or because (like the Aspeed
BMC SoCs), the pool of HW endpoints is shared between multiple gadgets.

The allocation side can be done rather easily using the existing
match_ep() UDC hook.

However we have no good place to "free" them.

This implements a "simple" variant of this, which calls an EP dispose
callback on all EPs associated with a gadget when the composite device
gets unbound.

This is required by my upcoming Aspeed vHub driver.

c6962c2972 usb: typec: tcpm: Set USB role switch to device mode when configured as such
Setting the mux to MUX_NONE and the switch to USB_SWITCH_DISCONNECT when
the data-role is device is not correct. Plenty of devices support
operating as USB device through a (separate) USB device controller.

We really need 2 different versions of USB_SWITCH_CONNECT,
USB_SWITCH_CONNECT_HOST and USB_SWITCH_DEVICE. Rather then modifying the
tcpc_usb_switch enum for this, simply remove it and switch to the
usb_role enum which provides exactly this, this will save use needing to
convert betweent the 2 enums when calling an usb-role-switch driver later.

Besides switching to the usb_role type, this commit also actually sets the
mux to TYPEC_MUX_USB and the switch to USB_ROLE_DEVICE instead of setting
both to none when the data-role is device.

This commit also makes tcpm_reset_port() call tcpm_mux_set(port,
TYPEC_MUX_NONE, USB_ROLE_NONE) so that the mux and switch
do _not_ stay in their last mode after a detach.

fde0aa6c17 usb: common: Small class for USB role switches
USB role switch is a device that can be used to choose the
data role for USB connector. With dual-role capable USB
controllers, the controller itself will be the switch, but
on some platforms the USB host and device controllers are
separate IPs and there is a mux between them and the
connector. On those platforms the mux driver will need to
register the switch.

With USB Type-C connectors, the host-to-device relationship
is negotiated over the Configuration Channel (CC). That
means the USB Type-C drivers need to be in control of the
role switch. The class provides a simple API for the USB
Type-C drivers for the control.

For other types of USB connectors (mainly microAB) the class
provides user space control via sysfs attribute file that
can be used to request role swapping from the switch.

178a0bce05 usb: core: hcd: integrate the PHY wrapper into the HCD core
This integrates the PHY wrapper into the core hcd infrastructure.
Multiple PHYs which are part of the HCD's device tree node are now
managed (= powered on/off when needed), by the new usb_phy_roothub code.

Suspend and resume is also supported, however not for
runtime/auto-suspend (which is triggered for example when no devices are
connected to the USB bus). This is needed on some SoCs (for example
Amlogic Meson GXL) because if the PHYs are disabled during auto-suspend
then devices which are plugged in afterwards are not seen by the host.

One example where this is required is the Amlogic GXL and GXM SoCs:
They are using a dwc3 USB controller with up to three ports enabled on
the internal roothub. Each port has it's own PHY which must be enabled
(if one of the PHYs is left disabled then none of the USB ports works at
all).
The new logic works on the Amlogic GXL and GXM SoCs because the dwc3
driver internally creates a xhci-hcd which then registers a HCD which
then triggers our new PHY wrapper.

USB controller drivers can opt out of this by setting
"skip_phy_initialization" in struct usb_hcd to true. This is identical
to how it works for a single USB PHY, so the "multiple PHY" handling is
disabled for drivers that opted out of the management logic of a single
PHY.

4e88d4c083 usb: add a flag to skip PHY initialization to struct usb_hcd
The USB HCD core driver parses the device-tree node for "phys" and
"usb-phys" properties. It also manages the power state of these PHYs
automatically.
However, drivers may opt-out of this behavior by setting "phy" or
"usb_phy" in struct usb_hcd to a non-null value. An example where this
is required is the "Qualcomm USB2 controller", implemented by the
chipidea driver. The hardware requires that the PHY is only powered on
after the "reset completed" event from the controller is received.

A follow-up patch will allow the USB HCD core driver to manage more than
one PHY. Add a new "skip_phy_initialization" bitflag to struct usb_hcd
so drivers can opt-out of any PHY management provided by the USB HCD
core driver.

This also updates the existing drivers so they use the new flag if they
want to opt out of the PHY management provided by the USB HCD core
driver. This means that for these drivers the new "multiple PHY"
handling (which will be added in a follow-up patch) will be disabled as
well.

5d6ae4f0da usb: gadget: composite: fix incorrect handling of OS desc requests
When handling an OS descriptor request, one of the first operations is
to zero out the request buffer using the wLength from the setup packet.
There is no bounds checking, so a wLength > 4096 would clobber memory
adjacent to the request buffer. Fix this by taking the min of wLength
and the request buffer length prior to the memset. While at it, define
the buffer length in a header file so that magic numbers don't appear
throughout the code.

When returning data to the host, the data length should be the min of
the wLength and the valid data we have to return. Currently we are
returning wLength, thus requests for a wLength greater than the amount
of data in the OS descriptor buffer would return invalid (albeit zero'd)
data following the valid descriptor data. Fix this by counting the
number of bytes when constructing the data and using this when
determining the length of the request.

cb88a05887 usb: quirks: add control message delay for 1b1c:1b20
Corsair Strafe RGB keyboard does not respond to usb control messages
sometimes and hence generates timeouts.

Commit de3af5bf25 ("usb: quirks: add delay init quirk for Corsair
Strafe RGB keyboard") tried to fix those timeouts by adding
USB_QUIRK_DELAY_INIT.

Unfortunately, even with this quirk timeouts of usb_control_msg()
can still be seen, but with a lower frequency (approx. 1 out of 15):

[   29.103520] usb 1-8: string descriptor 0 read error: -110
[   34.363097] usb 1-8: can't set config #1, error -110

Adding further delays to different locations where usb control
messages are issued just moves the timeouts to other locations,
e.g.:

[   35.400533] usbhid 1-8:1.0: can't add hid device: -110
[   35.401014] usbhid: probe of 1-8:1.0 failed with error -110

The only way to reliably avoid those issues is having a pause after
each usb control message. In approx. 200 boot cycles no more timeouts
were seen.

Addionaly, keep USB_QUIRK_DELAY_INIT as it turned out to be necessary
to have the delay in hub_port_connect() after hub_port_init().

The overall boot time seems not to be influenced by these additional
delays, even on fast machines and lightweight distributions.

7739376eb1 USB: of: clean up device-node helper
Clean up the USB device-node helper that is used to look up a device
node given a parent hub device and a port number. Also pass in a struct
usb_device as first argument to provide some type checking.

Give the helper the more descriptive name usb_of_get_device_node(),
which matches the new usb_of_get_interface_node() helper that is used to
look up a second type of of child node from a USB device.

Note that the terms "device node" and "interface node" are defined and
used by the OF Recommended Practice for USB.

1a7e3948cb USB: add device-tree support for interfaces
Add OF device-tree support for USB interfaces.

USB "interface nodes" are children of USB "device nodes" and are
identified by an interface number and a configuration value:

	&usb1 { /* host controller */
		dev1: device@1 { /* device at port 1 */
			compatible = "usb1234,5678";
			reg = <1>;

			#address-cells = <2>;
			#size-cells = <0>;

			interface@0,2 { /* interface 0 of configuration 2 */
				compatible = "usbif1234,5678.config2.0";
				reg = <0 2>;
			};
		};
	};

The configuration component is not included in the textual
representation of an interface-node unit address for configuration 1:

	&dev1 {
		interface@0 {	/* interface 0 of configuration 1 */
			compatible = "usbif1234,5678.config1.0";
			reg = <0 1>;
		};
	};

When a USB device of class 0 or 9 (hub) has only a single configuration
with a single interface, a special case "combined node" is used instead
of a device node with an interface node:

	&usb1 {
		device@2 {
			compatible = "usb1234,abcd";
			reg = <2>;
		};
	};

Combined nodes are shared by the two device structures representing the
USB device and its interface in the kernel's device model.

Note that, as for device nodes, the compatible strings for interface
nodes are currently not used.

For more details see "Open Firmware Recommended Practice: Universal
Serial Bus Version 1" and the binding documentation.

449fcf3ab0 Staging/IIO patches for 4.15-rc1
Here is the "big" staging and IIO driver update for 4.15-rc1.
 
 Lots and lots of little changes, almost all minor code cleanups as the
 Outreachy application process happened during this development cycle.
 Also happened was a lot of IIO driver activity, and the typec USB code
 moving out of staging to drivers/usb (same commits are in the USB tree
 on a persistent branch to not cause merge issues.)
 
 Overall, it's a wash, I think we added a few hundred more lines than
 removed, but really only a few thousand were modified at all.
 
 All of these have been in linux-next for a while.  There might be a
 merge issue with Al's vfs tree in the pi433 driver (take his changes,
 they are always better), and the media tree with some of the odd atomisp
 cleanups (take the media tree's version).

5fd54ace47 USB: add SPDX identifiers to all remaining files in drivers/usb/
It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.

Update the drivers/usb/ and include/linux/usb* files with the correct
SPDX license identifier based on the license text in the file itself.
The SPDX identifier is a legally binding shorthand, which can be used
instead of the full boiler plate text.

This work is based on a script and data from Thomas Gleixner, Philippe
Ombredanne, and Kate Stewart.

b24413180f License cleanup: add SPDX GPL-2.0 license identifier to files with no license
Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.

By default all files without license information are under the default
license of the kernel, which is GPL version 2.

Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier.  The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.

This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.

How this work was done:

Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
 - file had no licensing information it it.
 - file was a */uapi/* one with no licensing information in it,
 - file was a */uapi/* one with existing licensing information,

Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.

The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne.  Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.

The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed.  Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.

Criteria used to select files for SPDX license identifier tagging was:
 - Files considered eligible had to be source code files.
 - Make and config files were included as candidates if they contained >5
   lines of source
 - File already had some variant of a license header in it (even if <5
   lines).

All documentation files were explicitly excluded.

The following heuristics were used to determine which SPDX license
identifiers to apply.

 - when both scanners couldn't find any license traces, file was
   considered to have no license information in it, and the top level
   COPYING file license applied.

   For non */uapi/* files that summary was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0                                              11139

   and resulted in the first patch in this series.

   If that file was a */uapi/* path one, it was "GPL-2.0 WITH
   Linux-syscall-note" otherwise it was "GPL-2.0".  Results of that was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0 WITH Linux-syscall-note                        930

   and resulted in the second patch in this series.

 - if a file had some form of licensing information in it, and was one
   of the */uapi/* ones, it was denoted with the Linux-syscall-note if
   any GPL family license was found in the file or had no licensing in
   it (per prior point).  Results summary:

   SPDX license identifier                            # files
   ---------------------------------------------------|------
   GPL-2.0 WITH Linux-syscall-note                       270
   GPL-2.0+ WITH Linux-syscall-note                      169
   ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause)    21
   ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause)    17
   LGPL-2.1+ WITH Linux-syscall-note                      15
   GPL-1.0+ WITH Linux-syscall-note                       14
   ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause)    5
   LGPL-2.0+ WITH Linux-syscall-note                       4
   LGPL-2.1 WITH Linux-syscall-note                        3
   ((GPL-2.0 WITH Linux-syscall-note) OR MIT)              3
   ((GPL-2.0 WITH Linux-syscall-note) AND MIT)             1

   and that resulted in the third patch in this series.

 - when the two scanners agreed on the detected license(s), that became
   the concluded license(s).

 - when there was disagreement between the two scanners (one detected a
   license but the other didn't, or they both detected different
   licenses) a manual inspection of the file occurred.

 - In most cases a manual inspection of the information in the file
   resulted in a clear resolution of the license that should apply (and
   which scanner probably needed to revisit its heuristics).

 - When it was not immediately clear, the license identifier was
   confirmed with lawyers working with the Linux Foundation.

 - If there was any question as to the appropriate license identifier,
   the file was flagged for further research and to be revisited later
   in time.

In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.

Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights.  The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.

Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.

In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.

Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
 - a full scancode scan run, collecting the matched texts, detected
   license ids and scores
 - reviewing anything where there was a license detected (about 500+
   files) to ensure that the applied SPDX license was correct
 - reviewing anything where there was no detection but the patch license
   was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
   SPDX license was correct

This produced a worksheet with 20 files needing minor correction.  This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.

These .csv files were then reviewed by Greg.  Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected.  This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.)  Finally Greg ran the script using the .csv files to
generate the patches.

8dd8d2c95d USB: Force disconnect Huawei 4G modem during suspend
When going into S3 suspend, the Acer TravelMate P648-M and P648-G3
laptops immediately wake up 3-4 seconds later for no obvious reason.

Unbinding the integrated Huawei 4G LTE modem before suspend avoids
the issue, even though we are not using the modem at all (checked
from rescue.target/runlevel1). The problem also occurs when the option
and cdc-ether modem drivers aren't loaded; it reproduces just with the
base usb driver. Under Windows the system can suspend fine.

Seeking a better fix, we've tried a lot of things, including:
 - Check that the device's power/wakeup is disabled
 - Check that remote wakeup is off at the USB level
 - All the quirks in drivers/usb/core/quirks.c e.g. USB_QUIRK_RESET_RESUME,
   USB_QUIRK_RESET, USB_QUIRK_IGNORE_REMOTE_WAKEUP, USB_QUIRK_NO_LPM.

but none of that makes any difference.

There are no errors in the logs showing any suspend/resume-related issues.
When the system wakes up due to the modem, log-wise it appears to be a
normal resume.

Introduce a quirk to disable the port during suspend when the modem is
detected.

The modem from the P648-G3 model is:

0f38672c62 usb: renesas_usbhs: add support for R-Car D3
This patch adds support for R-Car D3. This SoC needs to release
the PLL reset by the UGCTRL register. So, since this is not the same
as other R-Car Gen3 SoCs, this patch adds a new type as
"USBHS_TYPE_RCAR_GEN3_WITH_PLL".

581821ae7f usb: chipidea: udc: Support SKB alignment quirk
NVIDIA Tegra20 UDC can't cope with unaligned DMA and require a USB gadget
quirk that avoids SKB buffer alignment to be set in order to make Ethernet
Gadget working. Later Tegra generations do not require that quirk. Let's
add a new platform data flag that allows to enable USB gadget quirk for
platforms that require it.

a9081a008f usb: phy: Add USB charger support
This patch introduces the usb charger support based on usb phy that
makes an enhancement to a power driver. The basic conception of the
usb charger is that, when one usb charger is added or removed by
reporting from the extcon device state change, the usb charger will
report to power user to set the current limitation.

Power user can register a notifiee on the usb phy by issuing
usb_register_notifier() to get notified by charger status changes
or charger current changes.

we can notify what current to be drawn to power user according to
different charger type, and now we have 2 methods to get charger type.
One is get charger type from extcon subsystem, which also means the
charger state changes. Another is we can get the charger type from
USB controller detecting or PMIC detecting, and the charger state
changes should be told by issuing usb_phy_set_charger_state().
