From f56e63509985d23e8912beaf3c38b07f7a1b12c6 Mon Sep 17 00:00:00 2001 From: Keerthy Date: Wed, 23 Nov 2016 13:25:27 +0530 Subject: board: ti: dra71x-evm: Add PMIC support Add the pmic_data for LP873x PMIC which is used to power up dra71x-evm. Note: As per the DM[1] DRA71x supports only OP_NOM. So, updating the efuse registers only to use OPP_NOM irrespective of any CONFIG_DRA7__OPP_{NOM,od,high} is defined.
