+- clocks : References to SSI/SRC/MIX/CTU/DVC/AUDIO_CLK clocks. +- clock-names : List of necessary clock names.
"ssi-all", "ssi.X", "src.X", "mix.X", "ctu.X","dvc.X", "clk_a", "clk_b", "clk_c", "clk_i"Are all clock mandatory? r8a7778.dtsi doesn't have "ssi-all" and the mix, ctu, and dvc clocks. r8a7793.dtsi doesn't have the mix and ctu clocks.
It is case by case. If DT has rcar_sound,ctu, it needs "ctu.X" clocks. And driver doesn't care 1st clocs clock-name (= "ssi-all" here).
