Nit: Since that is more of a "system level"/standard property, it's typical not to document it. The property is not actually required if the inherited value is already correct. Still, it's obvious enough what this means, so I'd only suggest fixing this if you have to respin for some other reason. > +- clocks: Must contain one entry for the ADMA module clock, "adma_ape". > +- clock-names: Must contain the entry "adma_ape". Which clock is this in the CAR? I don't see any adma_ape clock documented in the TRM. Is there a dedicated reset signal for this module? If so, we should require a resets property.
