From c3847a395b7175558f83dfc7b3171775a3d4ecf2 Mon Sep 17 00:00:00 2001 From: "Vishwanathrao Badarkhe, Manish" Date: Thu, 7 Mar 2013 11:56:21 +0530 Subject: [PATCH] ARM: davinci: da850: add tps6507x regulator DT data Add tps6507x regulator device tree data to da850-evm by adding regulator consumers with tightened constraints and regulator-name.TPS6507x regulator handle can be obtained by using this regulator name. Regulator constraints are added as per da850 board file. Regulator names are given as per maximum output voltage the regulator is capable to provide. for e.g. regulator name for dcdc1 is "VDCDC1_3.3V". Also, add tps6507x PMIC I2C slave device under I2C0 node. Tested on da850-evm.
