[PATCH 0/8] PinePhone automatic device tree selection

[Samuel Holland]

All,

This patch series implements a feature to automatically choose the
right PinePhone device tree by probing the hardware. It then extends
the functionality to pass the chosen DTB name to the boot command.
Finally, I add device trees and a defconfig for the PinePhone.

I'm aware that Andre has concerns about updating the device tree files.
It would be unfortunate for this to block new hardware support. Since
the device trees are primarily maintained in the Linux repository, and
only copied here, I believe compatibility concerns should be directed
there, not here. In any case, the first 6 patches can be merged
independently, so I request that they be merged even if patches 7-8 are
not. I am mainly including the last two patches for ease of testing.
