This adds initial support for iMX8MQ's Display Controller Subsystem (DCSS). Some of its capabilities include:
- 4K@60fps;
- HDR10;
- one graphics and 2 video pipelines;
- on-the-fly decompression of compressed video and graphics;
The reference manual can be found here: https://www.nxp.com/webapp/Download?colCode=IMX8MDQLQRM
The current patch adds only basic functionality: one primary plane for graphics, linear, tiled and super-tiled buffers support (no graphics decompression yet), no HDR10 and no video planes.
Video planes support and HDR10 will be added in subsequent patches once per-plane de-gamma/CSC/gamma support is in.

.... return drm_bridge_attach(encoder, bridge, NULL, 0); ....
The above code-snippet tells that the display-driver rely on the bridge to create the connector. Could this by any chance be updated to the new way where the display driver creates the connector - and thus passing DRM_BRIDGE_ATTACH_NO_CONNECTOR as the flags argument?
OK, I can give this a shot and the changes will be part of a separate patch within this patchset, if that's ok with you. No need to go through and review the entire driver again for this...
Thanks, laurentiu
What bridges would be relevant? To check that the reelvant bridges are already ported.
