From be0647d556985ae58a42e7fc3751a293c418c41e Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Wed, 4 Dec 2013 22:11:06 -0800 Subject: [PATCH] ARM: shmobile: lager: add gpio/fixed regulator for SDHI Fixed regulator is used for SDHI0/2 Vcc. We should use da9063 driver for Vccq, but, it doesn't have regulator support at this point. This patch uses gpio-regulator for it as quick-hack.
