From 4ca94d81869f8c9ba3e72eac3a99d3eef29df991 Mon Sep 17 00:00:00 2001 From: Lokesh Vutla Date: Thu, 30 May 2013 02:54:33 +0000 Subject: ARM: OMAP4+: pmic: Make generic bus init and write functions Voltage scaling can be done in two ways: -> Using SR I2C -> Using GP I2C In order to support both, have a function pointer in pmic_data so that we can call as per our requirement.
