Subject: [PATCH v4 0/5] Add MediaTek PMIC keys support

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.

Chen Zhong (5):
  mfd: mt6397: create irq mappings in mfd core driver
  dt-bindings: input: Add document bindings for mtk-pmic-keys
  dt-bindings: mfd: Add bindings for the keys as subnode of PMIC
  input: Add MediaTek PMIC keys support
  mfd: mt6397: Add PMIC keys support to MT6397 driver
