The actual chip also has LDO1_IN (for digital core and charge pump) and DBVDD (for I/O). However in the Chromebook designs these two and AVDD are all provided from the same power rail, through separate filter banks.
Neither does the datasheet specify the ordering of AVDD, DBVDD, and LDO1_IN for power sequencing, just that three should be toggled together.
Should we model these? Or wait until some design actually splits these?
