Subject: [PATCH] arm64: dts: rockchip: add wolfvision pf5 visualizer
display
Add device tree overlay for the WolfVision PF5 Visualizer display.
Since there shall be additional variants of the WolfVision PF5 display in
future, move common definitions to a device tree include file.
Signed-off-by: Michael Riesch <michael.riesch@...fvision.net>

Habidere,
A further addition related to the WolfVision PF5 mainboard that
has been accepted recently.
Looking forward to your comments!
