From b9c93646fd5cb669d096fec5ad25a01f04cfde27 Mon Sep 17 00:00:00 2001 From: Kishon Vijay Abraham I Date: Thu, 3 Sep 2015 12:20:37 +0530 Subject: regulator: pbias: program pbias register offset in pbias driver Add separate compatible strings for every platform and populate the pbias register offset in the driver data. This helps avoid depending on the dt for pbias register offset. Also update the dt binding documentation for the new compatible strings.
