Hugo VilleneuveandDmitry Torokhov 2ca45e57ea Input: charlieplex_keypad - add GPIO charlieplex keypad
Add support for GPIO-based charlieplex keypad, allowing to control
N^2-N keys using N GPIO lines.

Reuse matrix keypad keymap to simplify, even if there is no concept
of rows and columns in this type of keyboard.

Dmitry Torokhov 534b9bdeb4 Input: tca6416-keypad - remove the driver
This input driver predates proper GPIO driver for the chip and now can
be replaced with the generic gpio-keys. Remove the driver.

commit
480a8ad683 ("mfd: adp5585: Add Analog Devices ADP5585 core support")

we overlapped support for the adp5585 device (gpiochip part of it) but
since it actually makes sense for the device to be supported under MFD, we
can complement it and add the keymap support for it (properly based on FW
properties). And that is what

The ADP5585 is a 10/11 input/output port expander with a built in keypad
matrix decoder, programmable logic, reset generator, and PWM generator.
This driver supports the keyboard function using the platform device
registered by the core MFD driver.

The ADP5589 has 19 pins and also features an unlock function.

Dmitry Torokhov dd29eadee1 Input: msc_touchkey - remove the driver
MCS-5000/5080 chips belong to the 1st generation of Melfas chips,
manufactured in 2000-2007.

The driver relies on custom platform data (no DT support) and there
never were any users of this driver in the mainline kernel. It is likely
that the driver was (like mcs5000_ts driver) was tested on S3C6410 NCP
board (with Samsung S3C6410 SoC), but the touchkey device was never
added to the board file. This board was removed in v6.3 in commit
743c8fbb90 ("ARM: s3c: remove most s3c64xx board support").

Remove the driver since there are no users.

Nuno SáandDmitry Torokhov 9d2b2e83ef Input: adp5588-keys - support gpi key events as 'gpio keys'
This change replaces the support for GPIs as key event generators.
Instead of reporting the events directly, we add a gpio based irqchip
so that these events can be consumed by keys defined in the gpio-keys
driver (as it's goal is indeed for keys on GPIOs capable of generating
interrupts). With this, the gpio-adp5588 driver can also be dropped.

The basic idea is that all the pins that are not being used as part of
the keymap matrix can be possibly requested as GPIOs by gpio-keys
(it's also fine to use these pins as plain interrupts though that's not
really the point).

Since the gpiochip now also has irqchip capabilities, we should only
remove it after we free the device interrupt (otherwise we could, in
theory, be handling GPIs interrupts while the gpiochip is concurrently
removed). Thus the call 'adp5588_gpio_add()' is moved and since the
setup phase also needs to come before making the gpios visible, we also
need to move 'adp5588_setup()'.

While at it, always select GPIOLIB so that we don't need to use #ifdef
guards.
