[PATCH v3 1/3] regulator: max14577: Add proper dt-compatible strings

From: Marek Szyprowski
Date: Fri May 22 2020 - 06:24:57 EST


Add device tree compatible strings and create proper modalias structures
to let this driver load automatically if compiled as module, because
max14577 MFD driver creates MFD cells with such compatible strings.

v3:
- sorted of_max14577_regulator_dt_match
v2:
- added .of_match_table pointer
