You cover only the "legacy" ones here. Did you look at those? The reason is that the bus data layout of the new packing at higher bit depth matches with packing at lower bit depths (half to be precise). That's why there's no need to define formats for the new packing methods at higher bit depths (the driver simply uses the packing at half of the bit depth). -- Terveisin, Sakari Ailus
