Dmitry Torokhov aef01aad89 Input: matrix-keypad - switch to using generic device properties 
Instead of being OF-specific, let's switch to using generic device
properties, which will make this code usable on ACPI, device tree and
legacy boards that use property sets.

As part of the change let's rename matrix_keypad_parse_of_params() to
matrix_keypad_parse_properties().

Scott Branden 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.
