[PATCH 11/22] dt-bindings: display: rockchip: Add binding for VOP2
From: Sascha Hauer <s.hauer@pengutronix.de>

dri-devel, linux-devicetree, linux-rockchip
Subsystem:
drm drivers, drm drivers and misc gpu patches, drm drivers for rockchip, open firmware and flattened device tree bindings, the rest · Maintainers:

The VOP2 is found on newer Rockchip SoCs like the rk3568 or the rk3566. The binding differs slightly from the existing VOP binding, so add a new binding file for it.
