Subject: [PATCH v3 0/4] Add support for iMX8MQ Display Controller Subsystem
Date: Fri, 6 Dec 2019 11:52:37 +0200 [thread overview]
Message-ID: <1575625964-27102-1-git-send-email-laurentiu.palcu@nxp.com> (raw)
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 v3:
* rebased to latest linux-next and made it compile as drmP.h was
removed;
* removed the patch adding the VIDEO2_PLL clock. It's already applied;
* removed an unnecessary 50ms sleep in the dcss_dtg_sync_set();
* fixed a a spurious hang reported by Lukas Hartmann and encountered
by me several times;
* mask DPR and DTG interrupts by default, as they may come enabled from
U-boot;
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;
