ARM: dts: rockchip: add operating points and armclk

A patch from »ARM: rockchip: add cpuclk handling - arm-soc part« in state Mainline for linux-kernel

From: Heiko Stuebner <heiko@...> Date: Fri, 5 Sep 2014 19:35:43 +0200

Commit-Message

Add basic OPP entries for current supported Rockchip SoCs. The operating points are currently very conservative, so individual boards may opt to redefine them. Signed-off-by: Heiko Stuebner <heiko@...> Reviewed-by: Kever Yang <kever.yang@...>
