I'm not sure what to make of this one. Presumably this is the same as the A10s, with some bits (TS, HDMI, I2S, GPS) removed. BTW you kept the GPS reset control in this one. Hans and others have said and IIRC proven that the sun5i is the same die, with some exposing more peripherals than others. Wouldn't it make sense to use the same CCU driver for all of them? It's not like Allwinner actually disabled the clock control or hardware block. If you don't like it, perhaps you can share the same set of definitions, but have separate lists of what clocks are registered, for each SoC variant. That would at least cut down on code size and the effort to maintain 3 copies of almost the exact same thing. I guess the same applies to the GR8 CCU driver patch. And the comments from the previous (A10s CCU driver) patch applies to both. Let me know what you think. Regards ChenYu
