Subject: [PATCH v3 0/6] drm/rockchip: vop2: add support for the rgb output block

Hi all,

This series adds support for the RGB output block that can be found in the
Rockchip Video Output Processor (VOP) 2. Version 2 of this series
incorporates the feedback by Dan Carpenter and Sascha Hauer. Version 3
fixes a dumb mistake pointed out by Sascha :-) Thanks for your comments!

Patches 1-4 clean up the code and make it more general.

Patch 5 activates the support for the RGB output block in the VOP2 driver.

Patch 6 adds pinctrls for the 16-bit and 18-bit RGB data lines.

Tested on a custom board featuring the RK3568 SoC with a 18-bit RGB
display.

Looking forward to your comments!

Best regards,
Michael
