d3dc6e2322 input: keyboard: imx: add snvs power key driver
add snvs power key driver.
It work in imx chips after i.mx6sx

ON/OFF key used power on/off whole system.
This driver make it wakeup from suspend state when short press
ON/OFF key.

Long time press will trig SNVS power off chip without software
intervention.

0c7e67a928 Input: add driver for Broadcom keypad controller
Broadcom Keypad controller is used to interface a SoC with a matrix-type
keypad device. The keypad controller supports multiple row and column
lines. A key can be placed at each intersection of a unique row and a
unique column. The keypad controller can sense a key-press and key-release
and report the event using an interrupt to the CPU.

af6a5af8e8 Input: add new sun4i-lradc-keys driver
Allwinnner sunxi SoCs have a low resolution adc (called lradc) which is
specifically designed to have various (tablet) keys (ie home, back, search,
etc). attached to it using a resistor network. This adds a driver for this.

There are 2 channels, currently this driver only supports chan0 since there
are no boards known to use chan1.

This has been tested on an olimex a10s-olinuxino-micro, a13-olinuxino, and
a20-olinuxino-micro.

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.

Alberto Panizzo
76cdc083f4 Input: add imx-keypad driver to support the IMX Keypad Port
The IMX family of Application Processors is shipped with a Keypad Port
supported by this driver.

The peripheral can control up to an 8x8 matrix key pad where all the
scanning is done via software.  The hardware provides two interrupts:
one for key presses (KDI) and one for all key releases (KRI). There is
also a simple circuit for glitch reduction (said for synchronization)
made by two series of 3 D-latches clocked by the keypad-clock that
stabilize the interrupts sources. KDI and KRI are fired only if the
respective conditions are maintained for at last 4 keypad-clock cycle.

Since those circuits are poor for a correct debounce process (the
keypad-clock frequency is 32K and bounces longer than 94us are not
masked) the driver, when an interrupt arrives, samples the matrix
with a period of 10ms until the readins are stable for
IMX_KEYPAD_SCANS_FOR_STABILITY times (currently set at 3). After
getting stable result appropriate events are sent through the input
stack.

If some keys are maintained pressed, the driver continues to scan
the matrix with a longer period (60ms) to catch possible multiple
key presses without overloading the cpu. This process ends when all
keys are released.

This driver is tested to build in kernel or as a module and follow
the specification of Freescale Application processors:
i.MX25 i.MX27 i.MX31 i.MX35 i.MX51 especially tested on i.MX31.

fde1132374 Input: add driver for Atmel AT42QT2160 Sensor Chip
This version only supports individual cells (no slide support yet).
The code has been tested on proprietary development ARM board, but
should work fine on other machines.

9d8340687c Input: add twl4030_keypad driver
Add a driver for the keypad controller on TWL4030 family chips.
These support up to an 8x8 key matrix.  The TWL4030 multifunction
chips are mostly used on OMAP3 (or OMAP 2430) based boards.

bab7614d6d Input: add support for generic GPIO-based matrix keypad
Original patch by Marek Vasut, modified by Eric in:

1. use delayed work to simplify the debouncing
2. combine col_polarity/row_polarity into a single active_low field
3. use a generic bit array based XOR algorithm to detect key
   press/release, which should make the column assertion time
   shorter and code a bit cleaner
4. remove the ALT_FN handling, which is no way generic, the ALT_FN
   key should be treated as no different from other keys, and
   translation will be done by user space by commands like 'loadkeys'.
5. explicitly disable row IRQs and flush potential pending work,
   and schedule an immediate scan after resuming as suggested
   by Uli Luckas
6. incorporate review comments from many others

Patch tested on Littleton/PXA310 (though PXA310 has a dedicate keypad
controller, I have to configure those pins as generic GPIO to use this
driver, works quite well, though), and Sharp Zaurus model SL-C7x0
and SL-C1000.
