I've mixed feelings about this set. I'd either put patches 3-8 first since
e.g. 6/11 and 8/11 are fixing existing issues or even better to split CCGx
UCSI stuff into another set.

I have sent v2 with DesignWare patches only and no conversion part included.


It will be good we can take this patch also in this series. This is more nicer and cleaner solution. That said, we are working futuristic platform where CCGX is connected over system i2c of our platform i.e AMDI0010 so in this case from designware platform i2c driver we will have to probe the CCGX driver.
