[PATCH v2 3/3] arm64: dts: rockchip: Increase VOP clk rate on RK3328
Posted by Elaine Zhang 5 days, 16 hours ago
The VOP on RK3328 needs to run at a higher rate in order to produce
a proper 3840x2160 signal.
Change to use 300MHz for VIO clk and 400MHz for VOP clk.

Fixes: 0f2ddb128fa2 ("arm64: dts: rockchip: Increase VOP clk rate on RK3328")
