Marc Zyngier a1e5cd9650 ARM: Bulk conversion to generic_handle_domain_irq()
Wherever possible, replace constructs that match either
generic_handle_irq(irq_find_mapping()) or
generic_handle_irq(irq_linear_revmap()) to a single call to
generic_handle_domain_irq().

Marc Zyngier be1c2bb3ba ARM: PXA: Fix cplds irqdesc allocation when using legacy mode
The Mainstone PXA platform uses CONFIG_SPARSE_IRQ, and thus we
cannot rely on the irq descriptors to be readilly allocated
before creating the irqdomain in legacy mode. The kernel then
complains loudly about not being able to associate the interrupt
in the domain -- can't blame it.

Fix it by allocating the irqdescs upfront in the legacy case.

Linus Torvalds 4a0225c3d2 spi: Updates for v5.13
The only core work for SPI this time around is the completion of the
 conversion to the new style method for specifying transfer delays,
 meaning we can cope with what most controllers support more directly
 using conversions in the core rather than open coding in drivers.
 Otherwise it's a good stack of cleanups and fixes plus a few new
 drivers.
 
 The conversion to new style transfer delay will cause an issue with a
 newly added staging driver which has a straightforward resolution in
 -next.
 
  - Completion of the conversion to new style transfer delay
    configuration.
  - Introduction and use of module_parport_driver() helper, merged here
    as there's no parport tree.
  - Support for Altera SoCs on DFL buses, NXP i.MX8DL, HiSilicon Kunpeng,
    MediaTek MT8195,

Linus Torvalds 91552ab8ff The usual updates from the irq departement:
Core changes:
 
  - Provide IRQF_NO_AUTOEN as a flag for request*_irq() so drivers can be
    cleaned up which either use a seperate mechanism to prevent auto-enable
    at request time or have a racy mechanism which disables the interrupt
    right after request.
 
  - Get rid of the last usage of irq_create_identity_mapping() and remove
    the interface.
 
  - An overhaul of tasklet_disable(). Most usage sites of tasklet_disable()
    are in task context and usually in cleanup, teardown code pathes.
    tasklet_disable() spinwaits for a tasklet which is currently executed.
    That's not only a problem for PREEMPT_RT where this can lead to a live
    lock when the disabling task preempts the softirq thread. It's also
    problematic in context of virtualization when the vCPU which runs the
    tasklet is scheduled out and the disabling code has to spin wait until
    it's scheduled back in. Though there are a few code pathes which invoke
    tasklet_disable() from non-sleepable context. For these a new disable
    variant which still spinwaits is provided which allows to switch
    tasklet_disable() to a sleep wait mechanism. For the atomic use cases
    this does not solve the live lock issue on PREEMPT_RT. That is mitigated
    by blocking on the RT specific softirq lock.
 
  - The PREEMPT_RT specific implementation of softirq processing and
    local_bh_disable/enable().
 
    On RT enabled kernels soft interrupt processing happens always in task
    context and all interrupt handlers, which are not explicitly marked to
    be invoked in hard interrupt context are forced into task context as
    well. This allows to protect against softirq processing with a per
    CPU lock, which in turn allows to make BH disabled regions preemptible.
 
    Most of the softirq handling code is still shared. The RT/non-RT
    specific differences are addressed with a set of inline functions which
    provide the context specific functionality. The local_bh_disable() /
    local_bh_enable() mechanism are obviously seperate.
 
  - The usual set of small improvements and cleanups
 
 Driver changes:
 
  - New drivers for Nuvoton WPCM450 and DT 79rc3243x interrupt controllers
 
  - Extended functionality for MStar, STM32 and SC7280 irq chips
 
  - Enhanced robustness for ARM GICv3/4.1 drivers
 
  - The usual set of cleanups and improvements all over the place

Ezequiel Garcia a52e173619 media: mach-pxa: Register the camera sensor fixed-rate clock
The pxa-camera capture driver currently registers a v4l2-clk
clock, named "mclk", to represent the mt9m111 sensor clock.

Register a proper fixed-rate clock using the generic clock framework,
which will allow to remove the v4l2-clk clock in the pxa-camera
driver in a follow-up commit.

Linus Walleij 93cc26fa8f backlight: lms283gf05: Convert to GPIO descriptors
This converts the lms283gf05 backlight driver to use GPIO
descriptors and switches the single PXA Palm Z2 device
over to defining these.

Since the platform data was only used to convey GPIO
information we can delete the platform data header.

Notice that we define the proper active low semantics in
the board file GPIO descriptor table (active low) and
assert the reset line by bringing it to "1" (asserted).

This converts the WM97xx driver to use a GPIO descriptor
instead of passing a GPIO number thru platform data.

Like everything else in the driver, use a simple local

After converting the driver I noticed that none of the

this, but hey, it is converted.

The soc_camera driver is about to be removed, so drop camera
support from this board. Note that the soc_camera driver itself has
long since been deprecated and can't be compiled anymore (it depends
on BROKEN), so camera support on this board has been broken for a long
time (at least since 4.9 when the pxa_camera.c was removed from soc_camera).

Note that there is a new pxa_camera.c driver that replaced the old
soc_camera based driver, but using that would require these boards to
be converted to use the device tree.

The PWM backlight still supports passing a enable GPIO line as

It turns out that ever board using this mechanism except one
is pass .enable_gpio = -1. So we drop all these cargo-culted -1's
from all instances of this platform data in the kernel.

The remaning board, Palm TC, is converted to pass a machine
descriptior table with the "enable" GPIO instead, and delete the
platform data entry for enable_gpio and the code handling it
and things should work smoothly with the new API.

Linus Walleij fdabc466f3 usb: phy: phy-gpio-vbus-usb: Convert to GPIO descriptors
Instead of using the legacy GPIO API and keeping track on
polarity inversion semantics in the driver, switch to use
GPIO descriptors for this driver and change all consumers
in the process.

This makes it possible to retire platform data completely:
the only remaining platform data member was "wakeup" which
was intended to make the vbus interrupt wakeup capable,
but was not set by any users and thus remained unused. VBUS
was not waking any devices up. Leave a comment about it so
later developers using the platform can consider setting it
to always enabled so plugging in USB wakes up the platform.

Daniel Vetter 97b67986f1 fbcon: call fbcon_fb_(un)registered directly
With

commit 6104c37094
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date:   Tue Aug 1 17:32:07 2017 +0200

    fbcon: Make fbcon a built-time depency for fbdev

we have a static dependency between fbcon and fbdev, and we can
replace the indirection through the notifier chain with a function
call.

v2: Sam Ravnborg noticed that mach-pxa/am200epd.c has a notifier too,
and listens to this.

...

Looking at the code it seems to wait for some fb to show up, so that
it can get the framebuffer base address from the fb_info struct. I
suspect his is some firmware fbdev. Then it uses that information to
let the real fbdev driver (metronomefb.c by the looks) get at the
framebuffer memory.

This doesn't looke like it's easy to fix (except by deleting the
entire thing, seems untouched since 2008, we might be able to get away
with that), so let's just stuff a few #ifdef into fb.h and fbmem.c and
cry over them for a bit.

Linus Walleij 01dc79cd6f
regulator: fixed/gpio: Pull inversion/OD into gpiolib
This pushes the handling of inversion semantics and open drain
settings to the GPIO descriptor and gpiolib. All affected board
files are also augmented.

This is especially nice since we don't have to have any
confusing flags passed around to the left and right littering
the fixed and GPIO regulator drivers and the regulator core.
It is all just very straight-forward: the core asks the GPIO
line to be asserted or deasserted and gpiolib deals with the
rest depending on how the platform is configured: if the line
is active low, it deals with that, if the line is open drain,
it deals with that too.

Linus Walleij d6cd33ad71
regulator: gpio: Convert to use descriptors
This converts the GPIO regulator driver to use decriptors only.

We have to let go of the array gpio handling: the fetched descriptors
are handled individually anyway, and the array retrieveal function
does not make it possible to retrieve each GPIO descriptor with
unique flags. Instead get them one by one.

We request the "enable" GPIO separately as before, and make sure
that this line is requested as nonexclusive since enable lines can
be shared and the regulator core expects this.

Most users of the GPIO regulator are using device tree.

There are two boards in the kernel using the gpio regulator from a
non-devicetree path: PXA hx4700 and magician. Make sure to switch
these over to use descriptors as well.

Vladimir Zapolskiy d62998480b ARM: pxa: remove unused empty mach/pxa25x-udc.h file
Commit c5418a0b98 ("usb: gadget: pxa25x_udc: move register definitions
from arch") removed inclusion of mach/pxa25x-udc.h from the PXA25x UDC
driver, the contents of the header file was also wiped out, however the
file itself hasn't been removed, now this change removes the unused empty
header file.

Daniel Mack 0f884f8a09 ARM: pxa: remove raumfeld board files and defconfig
These boards are now fully ported to device-tree, so the old implementation
can go away.

The defconfig needs downstream quirks anyway, so we can just remove it from
mainline.

Linus Torvalds 1205b62390 Included in this update:
- Florian Fainelli noticed that userspace segfaults caused by the lack
   of kernel-userspace helpers was hard to diagnose; we now issue a
   warning when userspace tries to use the helpers but the kernel has
   them disabled.
 
 - Ben Dooks wants compatibility for the old ATAG serial number with DT
   systems.
 
 - Some cleanup of assembly by Nicolas Pitre.
 
 - User accessors optimisation from Vincent Whitchurch.
 
 - More robust kdump on SMP systems from Yufen Wang.
 
 - Sebastian Andrzej Siewior noticed problems with the SMP "boot_lock"
   on RT kernels, and so we convert the Versatile series of platforms
   to use a raw spinlock instead, consolidating the Versatile
   implementation.  We entirely remove the boot_lock on OMAP systems,
   where it's unnecessary.  Further patches for other systems will be
   submitted for the following merge window.
 
 - Start switching old StrongARM-11x0 systems to use gpiolib rather
   than their private GPIO implementation - mostly PCMCIA bits.
 
 - ARM Kconfig cleanups.
 
 - Cleanup a mostly harmless mistake in the recent Spectre patch in 4.20
   (which had the effect that data that can be placed into the init
   sections was incorrectly always placed in the rodata section.)
