this clock-id patch is way to overloaded. Please split into 3 parts:

- completely new clock-ids
- changes to existing clock-ids
This also needs a very good reasoning, as such constant ids are
considered part of api and should not change to prevent breakage
with old devicetrees. So please double-check if the rename is really
necessary.
- cosmetics ... aka the indentation stuff

This is one such case where you need a very good reason

why is this clock going away?

In your pwm patch, all blocks use the same clocks, so
this rename should be unnecessary

Again reasoning required (that i2s1 has 2 channels
but not 8 should be ok for that)
