This is a basic driver for the Surface 3. I am not so sure it will work
with any firmwares as most values are encoded, but given that I only have
access to my current device with its firmware and I don't have the
datasheet, it should be OK for now.

Core infrastructural changes:
- Support for natively single-ended GPIO driver stages. This
means that if the hardware has registers to configure open
drain or open source configuration, we use that rather than
(as we did before) try to emulate it by switching the line
to an input to get high impedance. This is also documented
throughly in Documentation/gpio/driver.txt for those of you
who did not understand one word of what I just wrote.
- Start to do away with the unnecessarily complex and
unitelligible ARCH_REQUIRE_GPIOLIB and
ARCH_WANT_OPTIONAL_GPIOLIB, another evolutional artifact from
the time when the GPIO subsystem was unmaintained. Archs can
now just select GPIOLIB and be done with it, cleanups to
arches will trickle in for the next kernel. Some minor archs
ACKed the changes immediately so these are included in this
pull request.
- Advancing the use of the data pointer inside the GPIO device
for storing driver data by switching the PowerPC, Super-H
Unicore and a few other subarches or subsystem drivers in
ALSA SoC, Input, serial, SSB, staging etc to use it.
- The initialization now reads the input/output state of the
GPIO lines, so that each GPIO descriptor knows - if this
callback is implemented - whether the line is input or
output. This also reflects nicely in userspace "lsgpio".
- It is now possible to name GPIO producer names, line names,
from the device tree. (Platform data has been supported for
a while.) I bet we will get a similar mechanism for ACPI
one of those days. This makes is possible to get sensible
producer names for e.g. GPIO rails in "lsgpio" in userspace.
New drivers:
- New driver for the Loongson1.
- The XLP driver now supports Broadcom Vulcan ARM64.
- The IT87 driver now supports IT8620 and IT8628.
- The PCA953X driver now supports Galileo Gen2.
Driver improvements:
- MCP23S08 was switched to use the gpiolib irqchip helpers and
now also suppors level-triggered interrupts.
- 74x164 and RCAR now supports the .set_multiple() callback
- AMDPT was converted to use generic GPIO.
- TC3589x, TPS65218, SX150X, F7188X, MENZ127, VX855, WM831X, WM8994
support the new single ended callback for open drain
and in some cases open source.
- Implement the .get_direction() callback for a few more drivers
like PL061, Xgene.
Cleanups:
- Paul Gortmaker combed through the drivers and de-modularized
those who are not really modules.
- Move the GPIO poweroff DT bindings to the power subdir where
they belong.
- Rename gpio-generic.c to gpio-mmio.c, which is much more to the

Merge tag 'gpio-v4.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for kernel cycle v4.7:
Core infrastructural changes:
- Support for natively single-ended GPIO driver stages.
This means that if the hardware has registers to configure open
drain or open source configuration, we use that rather than (as we
did before) try to emulate it by switching the line to an input to
get high impedance.
This is also documented throughly in Documentation/gpio/driver.txt
for those of you who did not understand one word of what I just
wrote.
- Start to do away with the unnecessarily complex and unitelligible
ARCH_REQUIRE_GPIOLIB and ARCH_WANT_OPTIONAL_GPIOLIB, another
evolutional artifact from the time when the GPIO subsystem was
unmaintained.
Archs can now just select GPIOLIB and be done with it, cleanups to
arches will trickle in for the next kernel. Some minor archs ACKed
the changes immediately so these are included in this pull request.
- Advancing the use of the data pointer inside the GPIO device for
storing driver data by switching the PowerPC, Super-H Unicore and
a few other subarches or subsystem drivers in ALSA SoC, Input,
serial, SSB, staging etc to use it.
- The initialization now reads the input/output state of the GPIO
lines, so that each GPIO descriptor knows - if this callback is
implemented - whether the line is input or output. This also
reflects nicely in userspace "lsgpio".
- It is now possible to name GPIO producer names, line names, from
the device tree. (Platform data has been supported for a while).
I bet we will get a similar mechanism for ACPI one of those days.
This makes is possible to get sensible producer names for e.g.
GPIO rails in "lsgpio" in userspace.
New drivers:
- New driver for the Loongson1.
- The XLP driver now supports Broadcom Vulcan ARM64.
- The IT87 driver now supports IT8620 and IT8628.
- The PCA953X driver now supports Galileo Gen2.
Driver improvements:
- MCP23S08 was switched to use the gpiolib irqchip helpers and now
also suppors level-triggered interrupts.
- 74x164 and RCAR now supports the .set_multiple() callback
- AMDPT was converted to use generic GPIO.
- TC3589x, TPS65218, SX150X, F7188X, MENZ127, VX855, WM831X, WM8994
support the new single ended callback for open drain and in some
cases open source.
- Implement the .get_direction() callback for a few more drivers like
PL061, Xgene.
Cleanups:
- Paul Gortmaker combed through the drivers and de-modularized those
who are not really modules.
- Move the GPIO poweroff DT bindings to the power subdir where they
belong.
- Rename gpio-generic.c to gpio-mmio.c, which is much more to the
point. That's what it is handling, nothing more, nothing less"

If using IRQF_TRIGGER_FALLING, then there is a race here: if the reset
completes before we enable the IRQ, then CHG is already low and touch

A wrong decoding of the touch coordinate message causes a wrong touch
ID. Touch ID for dual touch must be 0 or 1.
According to the actual Neonode nine byte touch coordinate coding,
the state is transported in the lower nibble and the touch ID in
the higher nibble of payload byte five.

Instead of doing the dance with macro that either resolves to a pointer or

Also let's mark suspend and resume methods as __maybe_unused instead of
guarding them with an #ifdef and rely on linker to drop unused code. Doing
so should allow better compile coverage.

commit 6680884a44 ("Input: ad7879 - add option to correct xy axis")

This branch is the culmination of 5 years of effort to bring the ARMv6
and ARMv7 platforms together such that they can all be enabled and
boot the same kernel. It has been a tremendous amount of cleanup and
refactoring by a huge number of people, and creation of several new
(and major) subsystems to better abstract out all the platform details
in an appropriate manner.
The bulk of this branch is a large patchset from Arnd that brings several
of the more minor and older platforms we have closer to multiplatform
support. Among these are MMP, S3C64xx, Orion5x, mv78xx0 and realview
Much of this is moving around header files from old mach directories,
but there are also some cleanup patches of debug_ll (lowlevel debug
per-platform options) and other parts.
Linus Walleij also has some patchs to clean up the older ARM Realview
platforms by finally introducing DT support, and Rob Herring has some
for ARM Versatile which is now DT-only. Both of these platforms are
now multiplatform.
Finally, a couple of patches from Russell for Dove PMU, and a fix from
Valentin Rothberg for Exynos ADC, which were rebased on top of the
series to avoid conflicts.

Merge tag 'armsoc-multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC multiplatform code updates from Arnd Bergmann:
"This branch is the culmination of 5 years of effort to bring the ARMv6
and ARMv7 platforms together such that they can all be enabled and
boot the same kernel. It has been a tremendous amount of cleanup and
refactoring by a huge number of people, and creation of several new
(and major) subsystems to better abstract out all the platform details
in an appropriate manner.
The bulk of this branch is a large patchset from Arnd that brings
several of the more minor and older platforms we have closer to
multiplatform support. Among these are MMP, S3C64xx, Orion5x, mv78xx0
and realview Much of this is moving around header files from old mach
directories, but there are also some cleanup patches of debug_ll
(lowlevel debug per-platform options) and other parts.
Linus Walleij also has some patchs to clean up the older ARM Realview
platforms by finally introducing DT support, and Rob Herring has some
for ARM Versatile which is now DT-only. Both of these platforms are
now multiplatform.
Finally, a couple of patches from Russell for Dove PMU, and a fix from
Valentin Rothberg for Exynos ADC, which were rebased on top of the
series to avoid conflicts"

Infrastructural changes:
- In struct gpio_chip, rename the .dev node to .parent to better reflect
the fact that this is not the GPIO struct device abstraction. We will
add that soon so this would be totallt confusing.
- It was noted that the driver .get_value() callbacks was
sometimes reporting negative -ERR values to the gpiolib core, expecting
them to be propagated to consumer gpiod_get_value() and gpio_get_value()
calls. This was not happening, so as there was a mess of drivers
returning negative errors and some returning "anything else than zero"
to indicate that a line was active. As some would have bit 31 set to
indicate "line active" it clashed with negative error codes. This is
fixed by the largeish series clamping values in all drivers with
!!value to [0,1] and then augmenting the code to propagate error codes
to consumers. (Includes some ACKed patches in other subsystems.)
- Add a void *data pointer to struct gpio_chip. The container_of() design
pattern is indeed very nice, but we want to reform the struct gpio_chip
to be a non-volative, stateless business, and keep states internal to
the gpiolib to be able to hold on to the state when adding a proper
userspace ABI (character device) further down the road. To achieve this,
drivers need a handle at the internal state that is not dependent on
their struct gpio_chip() so we add gpiochip_add_data() and
gpiochip_get_data() following the pattern of many other subsystems.
All the "use gpiochip data pointer" patches transforms drivers to this
scheme.
- The Generic GPIO chip header has been merged into the general
<linux/gpio/driver.h> header, and the custom header for that removed.
Instead of having a separate mm_gpio_chip struct for these generic
drivers, merge that into struct gpio_chip, simplifying the code and
removing the need for separate and confusing includes.
Misc improvements:
- Stabilize the way GPIOs are looked up from the ACPI legacy
specification.
- Incremental driver features for PXA, PCA953X, Lantiq (patches from the
OpenWRT community), RCAR, Zynq, PL061, 104-idi-48
New drivers:
- Add a GPIO chip to the ALSA SoC AC97 driver.
- Add a new Broadcom NSP SoC driver (this lands in the pinctrl dir, but
the branch is merged here too to account for infrastructural changes).

Merge tag 'gpio-v4.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij:
"Here is the bulk of GPIO changes for v4.5.
Notably there are big refactorings mostly by myself, aimed at getting
the gpio_chip into a shape that makes me believe I can proceed to
preserve state for a proper userspace ABI (character device) that has
already been proposed once, but resulted in the feedback that I need
to go back and restructure stuff. So I've been restructuring stuff.
On the way I ran into brokenness (return code from the get_value()
callback) and had to fix it. Also, refactored generic GPIO to be
simpler.
Some of that is still waiting to trickle down from the subsystems all
over the kernel that provide random gpio_chips, I've touched every
single GPIO driver in the kernel now, oh man I didn't know I was
responsible for so much...
Apart from that we're churning along as usual.
I took some effort to test and retest so it should merge nicely and we
shook out a couple of bugs in -next.

Remove write to REG_IRQCLR and REG_IRQWAKEUP in interrupt handler for
IRQENB_HW_PEN as the resume handler should and does clear REG_IRQWAKEUP.
IRQENB_HW_PEN bit is set in irqclr so that all interrupts get cleared
later so let IRQENB_HW_PEN be cleared by that.
Without this patch wakeup events from TSC_ADC do not work because pending
interrupts in TSC_ADC were causing HW_PEN interrupt, needed for wake from
suspend modes, to get disabled immediately by IRQ handler after being
enabled and preventing wake from happening.

The queue_setup callback has a void pointer that is just for V4L2
and is the pointer to the v4l2_format struct that was passed to
VIDIOC_CREATE_BUFS. The idea was that drivers would use the information
from that struct to buffers suitable for the requested format.
After the vb2 split series this pointer is now a void pointer,
which is ugly, and the reality is that all existing drivers will
effectively just look at the sizeimage field of v4l2_format.
To make this more generic the queue_setup callback is changed:
the void pointer is dropped, instead if the *num_planes argument
is 0, then use the current format size, if it is non-zero, then
it contains the number of requested planes and the sizes array
contains the requested sizes. If either is unsupported, then return
-EINVAL, otherwise use the requested size(s).

The goodix touchscreen driver uses a "rotated_screen" flag for
systems on which the touchscreen is mounted rotated by 180
degrees with respect to the display. With the addition of
support for the dt properties "touchscreen-inverted-x" and
"touchscreen-inverted-y", a separate "rotated_screen" flag
is not necessary anymore. This patch replaces it by setting
the inverted_x and inverted_y flags instead.
