This isn't particularly crucial, but I wonder if we can do something
similar to a jh7110-common.dtsi arrangement, where most of the boards
sharing similar designs can also share devicetree source files.

Easier said than done, probably, but I think it should be possible by
just comparing the vendor dts files.

Again this doesn't need to block this patch.

Yixun: I'm assuming you'll be handling this. What do you think about a
k1-common.dtsi?
