It will definitively help to remove some of the non-DT code in all our
former-common drivers.

Quick look at the patches (file path mostly) seems okay:

Acked-by: Nicolas Ferre <nicolas.ferre@microchip.com>

And thanks a lot to Haavard and you Hans-Christian for having developed,
more than 10 years ago, and then maintained some of the nice early
drivers that we are still using for our ARM-based platforms!
