Rather than relying on machine specific headers to
pass down the reboot status and the register locations,
use resources and platform_data.
Aside from this, keep the changes to a minimum.

Only the pxafb driver uses this header, so move it into the
same directory. The SMART_* macros are required by some
platform data definitions and can go into the
linux/platform_data/video-pxafb.h header.

There are two identical copies of mach/bitfield.h, one for
mach-sa1100 and one for mach-pxa. The pxafb driver only
makes use of two macros, which can be trivially open-coded
in the header.

The mach/hardware.h is included in lots of places, and it provides
three different things on pxa:
- the cpu_is_pxa* macros
- an indirect inclusion of mach/addr-map.h
- the __REG() and io_pv2() helper macros
Split it up into separate <linux/soc/pxa/cpu.h> and mach/pxa-regs.h
headers, then change all the files that use mach/hardware.h to
include the exact set of those three headers that they actually
need, allowing for further more targeted cleanup.
linux/soc/pxa/cpu.h can remain permanently exported and is now in
a global location along with similar headers. pxa-regs.h and
addr-map.h are only used in a very small number of drivers now
and can be moved to arch/arm/mach-pxa/ directly when those drivers
are to pass the necessary data as resources.

I have no reason to believe these boards have any more users and I
haven't tested them for several years. Removing them may simplify
other changes to the various PXA boards people still care about.
The recent conversion of pxa2xx_spi to GPIO descriptors for example
had to update this board despite no one caring or testing.

This converts the PXA2xx SPI driver to use GPIO descriptors
exclusively to retrieve GPIO chip select lines.
The device tree and ACPI paths of the driver already use
descriptors, hence ->use_gpio_descriptors is already set and
this codepath is well tested.
Convert all the PXA boards providing chip select GPIOs as
platform data and drop the old GPIO chipselect handling in
favor of the core managing it exclusively.

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.

Pull irq updates from Thomas Gleixner:
"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.
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

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
variable for the descriptor, it can only ever appear in
one instance anyway so it should not hurt.
After converting the driver I noticed that none of the
boardfiles actually define a meaningful GPIO line for
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.

As these boards have no more users nor testers, and patching them has
become a burden, be that because of the PCI part or the MTD NAND
support, let's remove them.
The cm-x300 will for now remain and represent Compulab boards at its
best in the PXA department.

The code in the Corgi backlight driver can be considerably
simplified by moving to GPIO descriptors and lookup tables
from the board files instead of passing GPIO numbers using
the old API.
Make sure to encode inversion semantics for the Akita and
Spitz platforms inside the GPIO lookup table and drop the
custom inversion semantics from the driver.
All in-tree users are converted in this patch.

The PWM backlight still supports passing a enable GPIO line as
platform data using the legacy <linux/gpio.h> API.
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.

Pull USB/Thunderbolt/PHY driver updates from Greg KH:
"Here is the big USB and Thunderbolt and PHY driver updates for
5.6-rc1.
With the advent of USB4, "Thunderbolt" has really become USB4, so the
renaming of the Kconfig option and starting to share subsystem code
has begun, hence both subsystems coming in through the same tree here.
PHY driver updates also touched USB drivers, so that is coming in
through here as well.
Major stuff included in here are:
- USB 4 initial support added (i.e. Thunderbolt)
- musb driver updates
- USB gadget driver updates
- PHY driver updates
- USB PHY driver updates
- lots of USB serial stuff fixed up
- USB typec updates
- USB-IP fixes
- lots of other smaller USB driver updates
All of these have been in linux-next for a while now (the usb-serial
tree is already tested in linux-next on its own before merged into
here), with no reported issues"

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.

commit 6104c37094e729f3d4ce65797002112735d49cd1
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.
