I believe that Laurent should handle this.

This seems fine and independent of the other patches.
But unfortunately it no longer applies.

Feel free to rebase it if you would like me to queue it up sooner

I assume this depends on 1/3.

Please add a patch to update the koelsch defconfig.

This seems reasonable but I assume it depends on earlier patches.

Please add a patch to update the koelsch defconfig or Kconfig.
