Hi Chen-Yu,

It looks mostly fine but...

I realise you're just using the A31 code, but it's actually the only
clock so far that uses clock-indices, while all the other clocks
relies on a bitmask.

I'd prefer to remain consistent and use a bitmask here as well (that
would also mean removing the clock-indices related code in the A31
driver)

Thanks,
Maxime
