[PATCH v2 0/5] Add support for iMX8MQ Display Controller Subsystem

Hi,

This patchset adds initial DCSS support for iMX8MQ chip. Initial support
includes only graphics plane support (no video planes), no HDR10 capabilities,
no graphics decompression (only linear, tiled and super-tiled buffers allowed).

Support for the rest of the features will be added incrementally, in subsequent
patches.

The patchset was tested with both HDP driver (not yet upstreamed) and MIPI-DSI
(drivers already on the dri-devel ML).

Thanks,
Laurentiu

Changes in v2:
 * Removed '0x' in node's unit-address both in DT and yaml;
 * Made the address region size lowercase, to be consistent;
 * Removed some left-over references to P010;
 * Added a Kconfig dependency of DRM && ARCH_MXC. This will also silence compilation
   issues reported by kbuild for other architectures;
