From 167e62798ccd4172d02c8f10ca7010a301498aa3 Mon Sep 17 00:00:00 2001 From: Laxman Dewangan Date: Thu, 9 Aug 2012 16:30:37 +0530 Subject: [PATCH] ARM: dt: tegra: cardhu: add entry for PMIC TPS65911. Tegra30 based platform "cardhu" have the power management IC TPS65911 for the regulator. Adding DT entry for this device. Data are chosen from downstream kernel and making the voltage output as require by default for device to operate. The default interrupt line is HIGH from PMIC device and so inverting the interrupt detection line of PMU interrupt through configuring PMC. In this patch, do not registering LDO5 because the input supply for this rail is different for different version of cardhu i..e A02 and A04. The registration will be done once the dts file for cardhu A02 and A04 are added in follow on patches.
