Subject: [PATCH v2 3/6] ARM: dts: dra7: Increase max-voltage of pbias regulator
Date: Thu, 31 Aug 2017 15:48:46 +0530 [thread overview]
Message-ID: <20170831101849.9489-4-kishon@ti.com> (raw)
In-Reply-To: <20170831101849.9489-1-kishon@ti.com>
From: Ravikumar Kattekola <rk@ti.com>
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
