5447326ff7 Input: atkbd - correct MSC_SCAN events for force_release keys
Without the change either no scancode would be reported on release of
force_release keys, or - if the key is marked as force_release erroneously
- the release event and the scancode would be reported in separate reports
to the input layer.

c012067961 Input: atkbd - do not try 'deactivate' keyboard on any LG laptops
We are getting more and more reports about LG laptops not having
functioning keyboard if we try to deactivate keyboard during probe.
Given that having keyboard deactivated is merely "nice to have"
instead of a hard requirement for probing, let's disable it on all
LG boxes instead of trying to hunt down particular models.

This change is prompted by patches trying to add "LG Electronics"/"ROCKY"
and "LG Electronics"/"LW60-F27B" to the DMI list.

When trying to use the matrix-keypad driver with GPIO drivers that
require nested irq handlers (e.g. I2C GPIO adapters like PCA9554),
request_irq() fails because the GPIO driver requires a threaded
interrupt handler.

Use request_any_context_irq() to be able to use any GPIO driver as
keypad driver.

Previous algorithm was a bit conservative and complicating with respect to
identifying key ghosting.  This CL uses the bitops hamming weight function
(hweight8) to count the number of matching rows for colM & colN.  If that
number is > 1 ghosting is present.

Additionally it removes NULL keys and our one virtual keypress KEY_BATTERY
from consideration as these inputs are never physical keypresses.

997502f893 Input: max7359 - introduce the use of managed interfaces
This patch introduces the use of managed interfaces like devm_kzalloc,
devm_input_allocate_device, devm_request_threaded_irq etc. and does away
with the calls to free the allocated memory. The remove function is no
longer required and is completely done away with. Also, the labels in the
probe function are removed.

128bb95deb Input: add driver for Microchip's CAP1106
This patch adds a driver for Microchips CAP1106, an I2C driven, 6-channel
capacitive touch sensor.

For now, only the capacitive buttons are supported, and no specific
settings that can be tweaked for individual channels, except for the
device-wide sensitivity gain. The defaults seem to work just fine out of
the box, so I'll leave configurable parameters for someone who's in need
of them and who can actually measure the impact. All registers are
prepared, however. Many of them are just not used for now.

The implementation does not make any attempt to be compatible to platform
data driven boards, but fully depends on CONFIG_OF.

Power management functions are also left for volounteers with the ability
to actually test them.

d1fd345e20 mfd: cros_ec: Move EC interrupt to cros_ec_keyb
If we receive EC interrupts after the cros_ec driver has probed, but
before the cros_ec_keyb driver has probed, the cros_ec IRQ handler
will not run the cros_ec_keyb notifier and the EC will leave the IRQ
line asserted.  The cros_ec IRQ handler then returns IRQ_HANDLED and
the resulting flood of interrupts causes the machine to hang.

Since the EC interrupt is currently only used for the keyboard, move
the setup and handling of the EC interrupt to the cros_ec_keyb driver.

                           keypad->keycodes, input_dev);

it will internally calculate needed row shift and use it to fill the
keymap. Therefore when calculating the "scancode" we should no longer use
constant row shift but also calculate it from number of columns.

0a4ac2ea27 Input: fix ps2/serio module dependency
The ps2 mouse and keyboard drivers use the "serio" framework that they
correctly select in Kconfig, and that in turn depends on the i8042 driver,
which is also allowed to be disabled for architectures that don't have an
i8042.

However, Kconfig also allows i8042 to be built as a module while
the serio framework is built-in, which causes this link error:

drivers/built-in.o: In function `ps2_begin_command':
:(.text+0x26b6cc): undefined reference to `i8042_check_port_owner'
:(.text+0x26b6d4): undefined reference to `i8042_lock_chip'
drivers/built-in.o: In function `ps2_end_command':
:(.text+0x26b734): undefined reference to `i8042_check_port_owner'
:(.text+0x26b73c): undefined reference to `i8042_unlock_chip'

On x86, a specific 'select SERIO_I8042' takes care of it, but
not on the other architecture that potentially have a i8042.

This patch changes the Kconfig logic to ensure that whenever
there is an i8042, it does get used for the serio driver, avoiding
the link error above.
