I would prefer if we stick with the current scheme and just push this
into the device dts (or possibly some vendor-common dtsi if that's
applicable).

Simply just to follow what we do on other platforms.


PS. I see some patches has been applied, but as you resubmit this
series please split it per maintainer to make it obvious to each
maintainer that they should pick their part(s).

Thanks,
Bjorn
