From a134be34065d52cde948f4ab13d0c1f3d4462c40 Mon Sep 17 00:00:00 2001 From: Nishanth Menon Date: Tue, 19 Mar 2013 12:53:05 -0500 Subject: ARM: dts: OMAP3: use twl4030 vdd1 regulator for CPU Define VDD1 regulator in twl4030 DT and mark it as the supply for the various OMAP34xx/35xx/36xx/37xx platforms (all use TWL4030 variants with VDD1 supplying the CPU). NOTE: This currently will use I2C1 bus communication path to set the voltage in device tree boot. In the legacy non device tree boot, we continue to use twl-common.c which bypasses I2C1 bus communication path and uses I2C4 bus path using OMAP voltage libraries. We should eventually be able to use I2C4 path once we have voltage regulator for OMAP which is capable of using the voltage controller/voltage processor IP blocks.
