This series adds initial graphics support for the Rockchip RK356[68] SoCs. Graphics support is based around the VOP2 controller which replaces the VOP controller found on earlier Rockchip SoCs. The driver has been tested with HDMI support included in this series and MIPI-DSI which is not included because it needs some more work. The driver is taken from the downstream Rockchip kernel and heavily polished, most non standard features have been removed for now. I tested the driver with the libdrm modetest utility and also with weston with both pixman and panfrost driver support. Michael Riesch reported the driver to work on the RK3566 as well, but device tree support for this SoC is not yet included in this series.
The HDMI changes are based on patches from Benjamin Gaignard, but modified a bit as I found out that the HDMI port on the RK3568 only needs one additional clock, not two. Also I added regulator support which is needed to get the HDMI up on the rk3568-EVB board.
All review and testing feedback welcome
