[PATCH v2 3/6] ARM: dts: dra7: Increase max-voltage of pbias regulator

From: Kishon Vijay Abraham I <hidden>
Date: 2017-08-31 10:22:30
Also in: linux-devicetree, linux-mmc, linux-omap, lkml
Subsystem: the rest · Maintainer: Linus Torvalds

From: Ravikumar Kattekola <redacted>

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 ? DRA75x, DRA74x Technical reference manual- November 2016

Tested on:
DRA75x PG 2.0 REV H EVM
