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. Signed-off-by: Heiko Stuebner <heiko@sntech.de> --- arch/arm/boot/dts/rk3288-veyron.dtsi | 16 ++++++++++++++++ 1 file changed, 16 insertions(+)
