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

[Laurentiu Palcu]

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;
