2017-03-29Input: matrix_keypad - add option to drive inactive columnsDavid Rivshin
The gpio-matrix-keypad driver normally sets inactive columns as inputs while scanning. This does not work for all hardware, which may require the inactive columns to be actively driven in order to overcome any pull-ups/downs on the columns.

2015-10-30Documentation: devicetree: fix reference to legacy wakeup propertiesSudeep Holla
This patch marks all the reference to the legacy wakeup bindings and replaces them with the standard "wakeup-source" property. All these legacy property are also listed under a separate section in the generic wakeup-source binding document.

2015-07-23Input: matrix_keypad - change name of wakeup property to "wakeup-source"Dmitry Torokhov
Wakeup property of device is not Linux-specific, it describes intended system behavior regardless of the OS being used. Therefore let's drop "linux," prefix, and, while at it, use the same name as I2C bus does: "wakeup-source". We keep parsing old name to keep compatibility with old DTSes.

2012-11-20Input: matrix-keypad - add device tree supportAnilKumar Ch
Also the driver was modifued to take advantage of recent improvements in matrix_keypad_build_keymap() implementation, which automatically allocates memory for keymap. The driver was tested on AM335x EVM. Signed-off-by: AnilKumar Ch <anilkumar@ti.com> Acked-by: Rob Herring <rob.herring@calxeda.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
