Changes since v4:
- rebase to Linux 4.14-rc1
- add a common keyboard binding document
- use child device tree node to define each key
Changes since v3:
- make the naming to be consistent as mtk_pmic or MTK_PMIC
- add suspend/resume functions to enable/disable irq
- change binding properties to define wakeup sources
Changes since v2:
- use standard properties for keycodes and debounce time
- change to use platform_get_irq in leaf drivers
- use better ways to define IRQ resources
Changes since v1:
- create irq mappings in mfd core driver instead of leaf drivers
- remove some unused parts in mtk-pmic-keys driver
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 usually used to wake up system from sleep. Homekey
can used as volume down key due to board design. Long press keys can
shutdown PMIC, the mode can be choose to be one key only or two keys
together.
This series add support for key functions for MediaTek PMIC MT6397/MT6323.
