Yes, I mentioned in the cover letter that patch #1 should go through
the spi tree and #2-4 through the linux-samsung tree. I can split in
two series once I post as proper patches to make it more clear.

We discussed in the past about having a common .dtsi [0]. I'm not a
huge fan of a common .dtsi and I prefer to instead split common dts
fragments in a .dtsi that can be included in different dts.
That also better reflects what happens at the hw level IMHO since a
board may reuse a IP block. Doug Anderson seems to agree with me [1].
