[PATCH 2/2] ARM: dts: rockchip: change the correct voltage range for rk3288 evb board

From: Caesar Wang
Date: Wed Dec 02 2015 - 06:12:53 EST


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.

AFAIK, the 1.8v voltage is used by the SD3.0 card.
