From e30430745a268616c4450f8fcaa1c04dedd5e141 Mon Sep 17 00:00:00 2001 From: Caesar Wang Date: Fri, 20 Oct 2017 18:09:38 +0800 Subject: [PATCH] ARM: dts: rk3036: add the opp table for rk3036 In order to save power and improve the performance, we can add the opp table for rk3036 SoCs. Also, make sure the codec works happily, we should ensure the arm/logic voltage is greater than 1v.
