From afeb43f9b17618f1fa8fe8eaa900585fc9da5b5e Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Thu, 6 Aug 2015 22:57:08 +0200 Subject: [PATCH] ARM: dts: rockchip: update rk3288-veyron cpu operating points The generic operating points specified in rk3288.dtsi are specified by Rockchip as conservative and for all cases. In contrast the Veyron ChromeOS devices are supposed to use a special chip variant often called rk3288-c and use different operating points in their kernel also including a higher max frequency. So override the operating points for veyron devices.
