78a5b53e9f Input: soc_button_array - work around DSDTs which modify the irqflags
Some 2-in-1s which use the soc_button_array driver have this ugly issue in
their DSDT where the _LID method modifies the irq-type settings of the
GPIOs used for the power and home buttons. The intend of this AML code is
to disable these buttons when the lid is closed.

The AML does this by directly poking the GPIO controllers registers. This
is problematic because when re-enabling the irq, which happens whenever
_LID gets called with the lid open (e.g. on boot and on resume), it sets
the irq-type to IRQ_TYPE_LEVEL_LOW. Where as the gpio-keys driver programs
the type to, and expects it to be, IRQ_TYPE_EDGE_BOTH.

This commit adds a workaround for this which (on affected devices) does
not set gpio_keys_button.gpio on these 2-in-1s, instead it gets the irq for
the GPIO, configures it as IRQ_TYPE_LEVEL_LOW (to match how the _LID AML
code configures it) and passes the irq in gpio_keys_button.irq.

4e5d9c1983 Input: soc_button_array - add support for INT33D3 tablet-mode switch devices
According to the Microsoft documentation for Windows 8 convertible
devices, these devices should implement a PNP0C60 "laptop/slate mode state
indicator" ACPI device.

This device can work in 2 ways, if there is a GPIO which directly
indicates the device is in tablet-mode or not then the direct-gpio mode
should be used. If there is no such GPIO, but instead the events are
coming from e.g. the embedded-controller, then there should still be
a PNP0C60 ACPI device and event-injection should be used to send the
events. The drivers/platform/x86/intel-vbtn.c code is an example from
a standardized manner of doing the latter.

On various 2-in-1s with either a detachable keyboard, or with 360°
hinges, the direct GPIO mode is indicated by an ACPI device with a
HID of INT33D3, which contains a single GpioInt in its ACPI resource
table, which directly indicates if the device is in tablet-mode or not.

This commit adds support for this to the soc_button_array code, as
well as for the alternative ID9001 HID which some devices use
instead of the INT33D3 HID.

838fc8083b Input: soc_button_array - add active_low setting to soc_button_info
This is a preparation patch for adding support for Intel INT33D3
ACPI devices. These INT33D3 devices follow yet another Intel defined
(but not documented) ACPI GPIO button standard.

Unlike the ACPI GPIO button devices supported so far, the GPIO used in
the INT33D3 devices is active-high, rather then active-low.

This commit makes setting the gpio_keys_button.active_low flag
configurable through the soc_button_info struct and enables it for all
currently supported devices.

d431b9e6af Input: ims-pcu - return error code rather than -ENOMEM
Currently the assignment of -ENOMEM to error is redundant because error
is not being read and -ENOMEM is being hard coded as an error return.
Fix this by returning the error code in variable 'error'; this also
allows the error code from a failed call to input_register_device to
be preserved and returned to the caller rather than just returning
a possibly inappropriate -ENOMEM.

Kudos to Dan Carpenter for the suggestion of an improved fix.

9747070c11 Input: axp20x-pek - always register interrupt handlers
On some X86 devices we do not register an input-device, because the
power-button is also handled by the soc_button_array (GPIO) input driver,
and we want to avoid reporting power-button presses to userspace twice.

Sofar when we did this we also did not register our interrupt handlers,
since those were only necessary to report input events.

But on at least 2 device models the Medion Akoya E1239T and the GPD win,
the GPIO pin used by the soc_button_array driver for the power-button
cannot wakeup the system from suspend. Why this does not work is not clear,
I've tried comparing the value of all relevant registers on the Cherry
Trail SoC, with those from models where this does work. I've checked:
PMC registers: FUNC_DIS, FUNC_DIS2, SOIX_WAKE_EN, D3_STS_0, D3_STS_1,
D3_STDBY_STS_0, D3_STDBY_STS_1; PMC ACPI I/O regs: PM1_STS_EN, GPE0a_EN
and they all have identical contents in the working and non working cases.
I suspect that the firmware either sets some unknown register to a value
causing this, or that it turns off a power-plane which is necessary for
GPIO wakeups to work during suspend.

What does work on the Medion Akoya E1239T is letting the AXP288 wakeup
the system on a power-button press (the GPD win has a different PMIC).

Move the registering of the power-button press/release interrupt-handler
from axp20x_pek_probe_input_device() to axp20x_pek_probe() so that the
PMIC will wakeup the system on a power-button press, even if we do not
register an input device.

fe77f9bb11 Input: axp20x-pek - respect userspace wakeup configuration
Unlike most other power button drivers, this driver unconditionally
enables its wakeup IRQ. It should be using device_may_wakeup() to
respect the userspace configuration of wakeup sources.

Because the AXP20x MFD device uses regmap-irq, the AXP20x PEK IRQs are
nested off of regmap-irq's threaded interrupt handler. The device core
ignores such interrupts, so to actually disable wakeup, we must
explicitly disable all non-wakeup interrupts during suspend.

996d5d5f89 Input: pm8xxx-vib - fix handling of separate enable register
Setting the vibrator enable_mask is not implemented correctly:

For regmap_update_bits(map, reg, mask, val) we give in either
regs->enable_mask or 0 (= no-op) as mask and "val" as value.
But "val" actually refers to the vibrator voltage control register,
which has nothing to do with the enable_mask.

So we usually end up doing nothing when we really wanted
to enable the vibrator.

We want to set or clear the enable_mask (to enable/disable the vibrator).
Therefore, change the call to always modify the enable_mask
and set the bits only if we want to enable the vibrator.

ee1b4b2e7c Input: hp_sdc_rtc - remove dead chardev code
The driver contains half of the implementation of /dev/rtc, but this
was never completed, and it is now incompatible with the drivers/rtc
framework.

Remove the chardev completely. If anyone wants to add the functionality
later, that shoudl be done through rtc_register_device().

The remaining portions of the driver basically implement a single
procfs file that may or may not be used anywhere. Not sure why this
is in drivers/input/ though.

bcf0595789 Input: soc_button_array - partial revert of support for newer surface devices
Commit c394159310 ("Input: soc_button_array - add support for newer
surface devices") not only added support for the MSHW0040 ACPI HID,
but for some reason it also makes changes to the error handling of the
soc_button_lookup_gpio() call in soc_button_device_create(). Note ideally
this seamingly unrelated change would have been made in a separate commit,
with a message explaining the what and why of this change.

I guess this change may have been added to deal with -EPROBE_DEFER errors,
but in case of the existing support for PNP0C40 devices, treating
-EPROBE_DEFER as any other error is deliberate, see the comment this
commit adds for why.

The actual returning of -EPROBE_DEFER to the caller of soc_button_probe()
introduced by the new error checking causes a serious regression:

On devices with so called virtual GPIOs soc_button_lookup_gpio() will
always return -EPROBE_DEFER for these fake GPIOs, when this happens
during the second call of soc_button_device_create() we already have
successfully registered our first child. This causes the kernel to think
we are making progress with probing things even though we unregister the
child before again before we return the -EPROBE_DEFER. Since we are making
progress the kernel will retry deferred-probes again immediately ending
up stuck in a loop with the following showing in dmesg:

[  124.022697] input: gpio-keys as /devices/platform/INTCFD9:00/gpio-keys.0.auto/input/input6537

<continues on and on and on>

And 1 CPU core being stuck at 100% and udev hanging since it is waiting
for the modprobe of soc_button_array to return.

This patch reverts the soc_button_lookup_gpio() error handling changes,
fixing this regression.

Since commit f889beaaab ("Input: da9063 - report KEY_POWER instead of
KEY_SLEEP during power key-press") KEY_SLEEP isn't supported anymore. This
caused input device to not generate any events if "dlg,disable-key-power"
is set.

Fix this by unconditionally setting KEY_POWER capability, and not
declaring KEY_SLEEP.

ret =

platform_get_irq(E, ...)

platform_get_irq_byname(E, ...)

Power and volume button support for 5th and 6th generation Microsoft
Surface devices via soc_button_array.

Note that these devices use the same MSHW0040 device as on the Surface
Pro 4, however the implementation is different (GPIOs vs. ACPI
notifications). Thus some checking is required to ensure we only load
this driver on the correct devices.
