[PATCH v2 3/6] ARM: dts: dra7: Increase max-voltage of pbias regulator
From: Kishon Vijay Abraham I
Date: Thu Aug 31 2017 - 06:22:34 EST
From: Ravikumar Kattekola <rk@xxxxxx>
As per recent TRM, PBIAS cell on dra7 devices supports
3.3V and not 3.0V as documented earlier.
Update PBIAS regulator max voltage to match this.
Document reference:
SPRUI30C â DRA75x, DRA74x Technical reference manual- November 2016
Tested on:
DRA75x PG 2.0 REV H EVM
