It still needs to be communicated to the PHY from the controller, however that is not a problem I am trying to solve now. If I can't get consensus for PHY_QCOM_CSI2_MODE_SPLIT_DPHY then so be it. I'll aim for DPHY only and we can come back to this topic when someone actually tries to enable it. --- bod -- linux-phy mailing list linux-phy@lists.infradead.org https://lists.infradead.org/mailman/listinfo/linux-phy
