Thanks for the update!

Already applied by LinusW.

LinusW: do you want me to queue this together with the driver for v4.13,
or will you take this single patch for v4.12?

Will queue in sh-pfc-for-v4.13.

These are for Simon.

Does applying the DTS changes before the driver introduce regressions?
If no, Simon can queue them for v4.13.
If yes, they'll have to wait for v4.14.

Thanks!
