Hello again,

I've been working on v2 of this series and done some initial cleanup.

Right now it looks a bit like this:

Does this seem correct?
- reg is required by spi-controller
- port is listed in panel-common
- power-supply is listed in panel-common

I'm guessing that the required section just lists the minimal
properties needed for this specific device tree yaml?
There's nothing implied by allOf?
