Usually these patches should go through the respective platform
maintainer trees,
and from there into the soc tree, but time is a little short here.

I could apply them directly with the maintainer Acks, but I don't understand
the significance of you sending them now. Is something broken without the
three patches? Are these the only ones missing from Ard's original series,
or is this preparation? Would you expect the patches to get backported to
stable kernels?
