[PATCH v5 2/2] regulator: mt6392: Add support for MT6392 regulator

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The MT6392 is a regulator found on boards based on the MediaTek
MT8167, MT8516, and probably other SoCs. It is a so called PMIC and
connectcts as a slave to a SoC using SPI, wrapped inside PWRAP.

V5:
	* Removed unneeded code
	* Fix indentation
	* Rebased
	* Switched some regulator to be linear
	* Use C++ style header style
	* Fix copyrights
V4:
	* No change
V3:
	* fix regulator's of_match following the renaming of the of nodes.
V2:
	* no changes
