ARM: dts: rockchip: convert rk3288 to operating-points-v2
Operating points need to be present in each cpu core using it, not only the first one. With operating-points-v1 this would require duplicating this table into each cpu node. With opp-v2 we can share the same table on all nodes. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Acked-by: Viresh Kumar <viresh.kumar@linaro.org>
