I'd say that the two "bch" clocks are only used if you decide to configure the on-host hardware ECC engine and thus are not needed with software corrections, but I'm fine keeping the fourth described in all cases if that's simpler. Also,here the diff just shows that "if we provide a clocks property with this compatible, then we need to provide 4 members", I believe the "required" property is already filled somewhere with the clocks/clock-names properties? Thanks, Miquèl
