Subject: [PATCH v2 0/3] mfd: MT6358 PMIC button support

The MediaTek MT6358 PMIC has support for two buttons: PWR and HOME.

The interrupt logic is a little different than other PMICs from the
same family:
for MT6323 and MT6397, we have one interrupt source per button
* for MT6358, we have two interrupts lines per button: the press and
* release interrupts are distinct sources.

Changes since v1 at [1]:
- cover letter title prefixed with 'mfd'

This series depends on [2]

Mattijs Korpershoek (3):
mfd: mt6397: add mt6358 register definitions for power key
mfd: mt6397: keys: use named IRQs instead of index
mfd: mt6397: add PMIC keys for MT6358

Subject: [PATCH v2 3/3] mfd: mt6397: add PMIC keys for MT6358

Add compatible strings and interrupts for pmic keys
which serves as child device of MFD.

MT6358 has two interrupts per key: one for press, another one for
release (_R)
