Please see my reply to [PATCH 1/7] dt-bindings: display: renesas,du: Document Renesas R-Car R8A779MD M3Le , the CMM0,1,3 all seems to be on the chip and accessible. I think the CMM driver should be aware of the IP, even if it is unused, e.g. to bring it into low power state if needed. > And does the DU still need three clocks and three interrupts ? The Geist board schematic indicates that DU_DOTCLKIN1 is present on the SoC package and is supplied by Xtal X22 on the board, so I think the answer is "yes" for the first clock part of your question. As for the interrupt part, it seems DU1 is present, but not connected. That means the DU1 interrupt does exist, but is not going to be used. Do you prefer to describe it or leave it out ?
