a703d279c5 We have a small collection of core framework updates this time, mostly around
clk registration by clk providers and debugfs "nice to haves" for rate
 constraints. I'll highlight that we're now setting the clk_init_data pointer
 inside struct clk_hw to NULL during clk_register(), which may break some
 drivers that thought they could use that pointer during normal operations. That
 change has been sitting in next for a while now but maybe something is still
 broken. We'l see. Other than that the core framework changes aren't invasive
 and they're fixing bugs, simplifying, and making things better.
 
 On the clk driver side we got the usual addition of new SoC support, new
 features for existing drivers, and bug fixes scattered throughout. The biggest
 diffstat is the Amlogic driver that gained CPU clk support in addition to
 migrating to the new way of specifying clk parents. After that the Qualcomm,
 i.MX, Mediatek, and Rockchip clk drivers got support for various new SoCs and
 clock controllers from those vendors.
 
 Core:
  - Drop NULL checks in clk debugfs
  - Add min/max rates to clk debugfs
  - Set clk_init_data pointer inside clk_hw to NULL after registration
  - Make clk_bulk_get_all() return an 'id' corresponding to clock-names
  - Evict parents from parent cache when they're unregistered
 
 New Drivers:
  - Add clock driver for i.MX8MN SoCs
  - Support aspeed AST2600 SoCs
  - Support for Mediatek MT6779 SoCs
  - Support qcom SM8150 GCC and RPMh clks
  - Support qcom QCS404 WCSS clks
  - Add CPU clock support for Armada 7K/8K (specifically AP806 and AP807)
  - Addition of clock driver for Rockchip rk3308 SoCs
 
 Updates:
  - Add regulator support to the cdce925 clk driver
  - Add support for Raspberry Pi 4 bcm2711 SoCs
  - Add SDIO gate support to aspeed driver
  - Add missing of_node_put() calls in various clk drivers
  - Migrate Amlogic driver to new clock parent description method
  - Add DVFS support to Amlogic Meson g12
  - Add Amlogic Meson g12a reset support to the axg audio clock controller
  - Add sm1 support to the Amlogic Meson g12a clock controller
  - Switch i.MX8MM clock driver to platform driver
  - Add Hifi4 DSP related clocks for i.MX8QXP SoC
  - Fix Audio PLL setting and parent clock for USB
  - Misc i.MX8 clock driver improvements and corrections
  - Set floor ops for Qualcomm SD clks so that rounding works
  - Fix "always-on" Clock Domains on Renesas R-Car M1A, RZ/A1, RZ/A2, and RZ/N1
  - Enable the Allwinner V3 SoC and fix the i2s clock for H6

bd0e79f1da phy: ti: am654-serdes: Don't reference clk_init_data after registration
A future patch is going to change semantics of clk_register() so that
clk_hw::init is guaranteed to be NULL after a clk is registered. Avoid
referencing this member here so that we don't run into NULL pointer

 	- USB serial driver updates and fixes
 	- typec updates and new chips supported
 	- mtu3 driver updates
 	- xhci driver updates
 	- other tiny driver updates
 
 Nothing really interesting, just constant forward progress.
 
 All of these have been in linux-next for a while with no reported

71e2f5c5c2 phy: ti: Add a new SERDES driver for TI's AM654x SoC
Add a new SERDES driver for TI's AM654x SoC which configures
the SERDES only for PCIe. Support fo USB3 will be added later.

SERDES in am654x has three input clocks (left input, externel reference
clock and right input) and two output clocks (left output and right
output) in addition to a PLL mux clock which the SERDES uses for Clock
Multiplier Unit (CMU refclock).

The PLL mux clock can select from one of the three input clocks.
The right output can select between left input and external reference
clock while the left output can select between the right input and
external reference clock.

The driver has support to select PLL mux and left/right output mux as
specified in device tree.

d41ce98a12 phy: ti: usb2: fix OMAP_CONTROL_PHY dependency
With randconfig build testing on arm64, we can run into a configuration
that has CONFIG_OMAP_CONTROL_PHY=m and CONFIG_OMAP_USB2=y, which in turn
causes a link failure:

drivers/phy/ti/phy-omap-usb2.o: In function `omap_usb_phy_power':
phy-omap-usb2.c:(.text+0x17c): undefined reference to `omap_control_phy_power'

I could not come up with a good way to correctly describe the relation
of the two symbols, but if we just select CONFIG_OMAP_CONTROL_PHY
during compile testing, we can no longer run into the broken configuration.

20f795881f phy: phy-twl4030-usb: Fix cable state handling
With the recent regulator changes I noticed new warnings on doing rmmod of
phy-twl4030-usb:

WARNING: CPU: 0 PID: 1080 at drivers/regulator/core.c:2046 _regulator_put
...

Turns out we can currently miss disconnect at least for cases where status
is 0 and linkstat is 0. And in that case doing rmmod phy-twl4030-usb will
produce the regulator_put() warning.

This is because the missed disconnect causes unbalanced PM runtime calls
and the regulators will be on exit.

Let's fix the issue by using an atomic flag for the cable state to make
sure that PM runtime won't get out of sync with the cable state. That
way we can also simplify the code a bit.

Note that we can also drop the old comments, those relate to issues that
the battery charger driver and musb driver is dealing with rather than
the USB PHY driver.

92b58b3474 phy: ti: introduce phy-gmii-sel driver
TI am335x/am437x/dra7(am5)/dm814x CPSW3G Ethernet Subsystem supports two
10/100/1000 Ethernet ports with selectable G/MII, RMII, and RGMII
interfaces. The interface mode is selected by configuring the MII mode
selection register(s) (GMII_SEL) in the System Control Module chapter
(SCM). GMII_SEL register(s) and bit fields placement in SCM are different
between SoCs while fields meaning is the same.

Historically CPSW external Port's interface mode selection configuration
was introduced using custom API and driver cpsw-phy-sel.c. This leads to
unnecessary driver, DT binding and custom API support effort.

This patch introduces CPSW Port's PHY Interface Mode selection Driver
(phy-gmii-sel) which implements standard Linux PHY interface and used
as a replacement for TI's specific driver cpsw-phy-sel.c and corresponding
custom API.

79a5a18aa9 phy: core: rework phy_set_mode to accept phy mode and submode
Currently the attempt to add support for Ethernet interface mode PHY
(MII/GMII/RGMII) will lead to the necessity of extending enum phy_mode and
duplicate there values from phy_interface_t enum (or introduce more PHY
callbacks) [1]. Both approaches are ineffective and would lead to fast
bloating of enum phy_mode or struct phy_ops in the process of adding more
PHYs for different subsystems which will make them unmaintainable.

As discussed in [1] the solution could be to introduce dual level PHYs mode
configuration - PHY mode and PHY submode. The PHY mode will define generic
PHY type (subsystem - PCIE/ETHERNET/USB_) while the PHY submode - subsystem
specific interface mode. The last is usually already defined in
corresponding subsystem headers (phy_interface_t for Ethernet, enum
usb_device_speed for USB).

This patch is cumulative change which refactors PHY framework code to
support dual level PHYs mode configuration - PHY mode and PHY submode. It
extends .set_mode() callback to support additional parameter "int submode"
and converts all corresponding PHY drivers to support new .set_mode()
callback declaration.
The new extended PHY API
 int phy_set_mode_ext(struct phy *phy, enum phy_mode mode, int submode)
is introduced to support dual level PHYs mode configuration and existing
phy_set_mode() API is converted to macros, so PHY framework consumers do
not need to be changed (~21 matches).

A lazy getter function is used so that the regmap will only be
created if it is actually used. This function will also be used

The USB PHY driver is currently the only consumer. This driver is

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.

The AM572x Technical Reference Manual, SPRUHZ6H,
Revised November 2016 [1], shows recommended settings for the
SATA DPLL in Table 26-8. DPLL CLKDCOLDO Recommended Settings.

Use those settings in the driver. The TRM does not show
a value for 20MHz SYS_CLK so we use something close to the
26MHz setting.
