[PATCH 0/7] Input: mtk-pmic-keys - add support for MT6358

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.

These series:
* Fix a NULL ptr error when we use mtk-pmic-keys without dts code
* Rework the mt6397 driver to prepare for this different interrupt logic
* Add support for the MT6358 power buttons

This has been functionally tested (using evtest) on
the mt8183-pumpkin board on linux/master

It has also been used for a couple of months in a downstream
tree based on v5.4.
