Subject: [PATCH 0/4] Add MediaTek PMIC keys support

MediaTek PMIC are multi-function devices that can handle key
interrupts, typically there are two keys attached to PMIC, which
called pwrkey and homekey. PWRKEY is usually used to wake up system
from sleep. Homekey can be used as volume down key due to board
design. Long press keys can shutdown PMIC, the mode can be chosen
to be one key only or two keys together.
