Hi Justin, Heiko,

In the discussion about "rockchip,px30-rga" it was mentioned that:
"no status for soc internal components without any board-specifics".
The binding is in mainline, but the dts node is missing I think.
Should this also be changed?

yep, drop the status disabled from the dtsi and that then results
in not needing the board-level enablement

(background: rga is a simple mem2mem device without any
board-specific hooks)

Shall I submit version 5 of this patch series?

Add a node to define the presence of RGA, a 2D raster
graphic acceleration unit.
