Subject: [PATCH v3 0/2] rework bpi-r3 dts overlays and add SATA dtso

From: Frank Wunderlich <[email protected]>

This Series adds check for bpi-r3 dts overlays on buildtime
required by rob herring [1] and adds SATA overlay

Last version seems to get lost so posting v3 with updated sata
overlay syntax (removing the fragment).

Bananapi R3 has a Power socket entended for using external SATA drives.
This Socket is off by default but can be switched with gpio 8.

Add an overlay to activate it.
