Due to the lack of proper OPP definition, use an arbitrary safe value. - clock-latency = 300 us Approximate worst-case latency to do a full DVFS transition for every OPPs. Due to the lack of HW information, use an arbitrary safe value. Note: The term transition-latency will be more accurate to define this value since the clock transition latency is not the only parameter that will define the overall DVFS transition. - operating-points = < kHz - uV > List of 6 operating points. All of them are using the same voltage since DVS is not supported in R-CAR Gen2. - clocks phandle to the CPU clock source. This clock source is used for all the 2 CortexA15 located inside the same cluster. Signed-off-by: Gaku Inami Acked-by: Magnus Damm Signed-off-by: Simon Horman --- Reading git-diff-tree failed
