Raydium device does not like splitting of tx transactions into multiple
messages - one for the register address and one for the actual data. This
results in incorrect behavior on the device side.
This change updates raydium_i2c_read and raydium_i2c_write to create
i2c_msg arrays separately and passes those arrays into raydium_i2c_xfer
which decides based on the address whether the bank switch command should
be sent. The bank switch header is still added by raydium_i2c_read and
raydium_i2c_write to ensure that all these operations are performed as part
of a single I2C transfer. It guarantees that no other transactions are
initiated to any other device on the same bus after the bank switch command
is sent.

After commit 74d905d2d3 devices requiring the workaround for edge
triggered interrupts stopped working.
The hardware needs the quirk to be used before even proceeding to
check if the quirk is needed because mxt_acquire_irq() is called
before mxt_check_retrigen() is called and at this point pending IRQs
need to be checked, and if the workaround is not active, all
interrupts will be lost from this point.
Solve this by switching the calls around.

The i8042 module exports several symbols which may be used by other
modules.
Before this commit it would refuse to load (when built as a module itself)
on systems without an i8042 controller.
This is a problem specifically for the asus-nb-wmi module. Many Asus
laptops support the Asus WMI interface. Some of them have an i8042
controller and need to use i8042_install_filter() to filter some kbd
events. Other models do not have an i8042 controller (e.g. they use an
USB attached kbd).
Before this commit the asus-nb-wmi driver could not be loaded on Asus
models without an i8042 controller, when the i8042 code was built as
a module (as Arch Linux does) because the module_init function of the
i8042 module would fail with -ENODEV and thus the i8042_install_filter
symbol could not be loaded.
This commit fixes this by exiting from module_init with a return code
of 0 if no controller is found. It also adds a i8042_present bool to
make the module_exit function a no-op in this case and also adds a
check for i8042_present to the exported i8042_command function.
The latter i8042_present check should not really be necessary because
when builtin that function can already be used on systems without
an i8042 controller, but better safe then sorry.

On an AMD chromebook, where the same I2C bus is shared by both Raydium
touchscreen and a trackpad device, it is observed that interleaving of
I2C messages when `raydium_i2c_read_message()` is called leads to the
Raydium touch IC reporting incorrect information. This is the sequence
that was observed to result in the above issue:
* I2C write to Raydium device for RM_CMD_BANK_SWITCH
* I2C write to trackpad device
* I2C read from trackpad device
* I2C write to Raydium device for setting address
* I2C read from Raydium device >>>> This provides incorrect
information
This change adds a new helper function `raydium_i2c_xfer()` that
performs I2C transactions to the Raydium device. It uses the register
address to decide if RM_CMD_BANK_SWITCH header needs to be sent to the
device (i.e. if register address is greater than 255, then bank switch
header is sent before the rest of the transaction). Additionally, it
ensures that all the I2C operations performed as part of
`raydium_i2c_xfer()` are done as a single i2c_transfer. This
guarantees that no other transactions are initiated to any other
device on the same bus in between. Additionally,
`raydium_i2c_{send|read}*` functions are refactored to use this new
helper function.
Verified with the patch across multiple reboots (>100) that the
information reported by the Raydium touchscreen device during probe
is correct.

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.

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.

Unlike the ACPI GPIO button devices supported so far, the GPIO used in

Recently a new KEY_SELECTIVE_SCREENSHOT keycode was added by commit

quoting from the commit message:
"New Chrome OS keyboards have a "snip" key that is basically a selective
screenshot (allows a user to select an area of screen to be copied).
Allocate a keycode for it."
Support for this "snip" key seems like it is also a good match for the

This is a bit complicated, since EETI devices do not have
