From a1c2e133d26688a5783e1264cb6865b5d2bd9181 Mon Sep 17 00:00:00 2001 From: Caesar Wang Date: Wed, 2 Dec 2015 19:12:21 +0800 Subject: ARM: dts: rockchip: fix voltage ranges for rk3288-evb-act8846 board In general, the logic voltage is affected by ddr frequency factors. We should fix the correct voltage range since assuemd that we have the ddr frequency driver in mainline in the future. AFAIK, the 1.8v voltage is used by the SD3.0 card.
