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;
