From 7573287026ceb301510dfd0c07b75b52a71dc8ce Mon Sep 17 00:00:00 2001 From: Zhen Chen Date: Tue, 14 Jun 2016 15:16:11 +0800 Subject: [PATCH] ARM: dts: rockchip: fix vdd_cpu to 1.25V on rk3036 kylin board In rk3036, the voltages of CPU and GPU are controlled by the same regulator 'vdd_cpu'. Here, we fix it to 1.25v to ensure that GPU could work well in development period. The actual voltage GPU needs might be much lower, and relative to the frequency GPU runs at. this would be optimized when we implement GPU DVFS with devfreq.
