[PATCH] regulator: mt6397: Implement of_map_mode regulator_desc function
From: Anand K Mistry
Date: Mon Jun 29 2020 - 21:11:04 EST
Without a of_map_mode implementation, the regulator-allowed-modes
devicetree field is skipped, and attempting to change the regulator mode
results in an error:
[ 1.439165] vpca15: mode operation not allowed
