From 257bdb3f665117a6c5b34a4fd797778f98bd5d22 Mon Sep 17 00:00:00 2001 From: Vignesh R Date: Wed, 10 Aug 2016 15:17:20 +0530 Subject: ARM: dts: dra7xx-evm: add evm_3v3_sd regulator Add a node for evm_3v3_sd using onboard PCF GPIO expander which feeds on to mmc vdd. Update mapping for vmmc-supply and vmmc_aux-supply. evm_3v3_sd supplies to SD card vdd, and ldo1 to sdcard i/o lines.
