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.Signed-off-by: Hans Verkuil

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

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 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.Signed-off-by: Linus Walleij

Pull USB/Thunderbolt/PHY driver updates from Greg KH:
"Here is the big USB and Thunderbolt and PHY driver updates for

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.Cc: Daniel Mack

commit 6104c37094e729f3d4ce65797002112735d49cd1
Author: Daniel Vetter
Date: Tue Aug 1 17:32:07 2017 +0200fbcon: 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.Signed-off-by: Daniel Vetter

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.Cc: Alexander Shiyan # i.MX boards user

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.Cc: Philipp Zabel # Magician

Commit c5418a0b98c1 ("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.Signed-off-by: Vladimir Zapolskiy

It's also a slave controller driver now, calling it "master" is slightly

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.Signed-off-by: Daniel Mack

Pull ARM updates from Russell King:
"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)"* tag 'for-4.21' of git://git.armlinux.org.uk/~rmk/linux-arm: (25 commits)

Pull MMC updates from Ulf Hansson:
"This time, this pull request contains changes crossing subsystems and

After converting the PXA driver to use GPIO descriptors for
card detect and write protect it is relatively simple to
convert it to also use a descriptor for getting the optional
power control GPIO.The polarity inversion flag can also go away from the platform
data since this is indicated in the GPIO machine descriptor
table.Cc: Daniel Mack

This deletes the platform data passed for card detect and
write protect from various PXA machines.Make sure to keep .gpio_card_ro_invert as this is still in
use by some machines and needed to set the right flag to
the MMC core (will be cleaned up later).Cc: Daniel Mack

The Palm27x devices set up the MMC card detect and
write protect lines with a special helper function.
Augment this helper function to also accept an optional
GPIO descriptor table and pass and register this for
all the Palm27x devices in that family.Cc: Daniel Mack
