Hi Rafael, There is a custom operation region for the WhiskeyCove PMIC device named REGS used at least on some of the Broxton based platform which is missing support at the moment. At least the USB Type-C PHY depends on this operation region. Bin Gao had send patches [1] that add support for the Whiskey Cove PMIC operation region, but that patch does not cover this particular operation region.
