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; Laurentiu Palcu (4): drm/imx: compile imx directory by default drm/imx: Add initial support for DCSS on iMX8MQ dt-bindings: display: imx: add bindings for DCSS arm64: dts: imx8mq: add DCSS node .../bindings/display/imx/nxp,imx8mq-dcss.yaml | 86 +++ arch/arm64/boot/dts/freescale/imx8mq.dtsi | 25 + drivers/gpu/drm/Makefile | 2 +- drivers/gpu/drm/imx/Kconfig | 2 + drivers/gpu/drm/imx/Makefile | 1 + drivers/gpu/drm/imx/dcss/Kconfig | 8 + drivers/gpu/drm/imx/dcss/Makefile | 6 + drivers/gpu/drm/imx/dcss/dcss-blkctl.c | 75 ++ drivers/gpu/drm/imx/dcss/dcss-crtc.c | 224 ++++++ drivers/gpu/drm/imx/dcss/dcss-ctxld.c | 447 +++++++++++ drivers/gpu/drm/imx/dcss/dcss-dev.c | 286 +++++++ drivers/gpu/drm/imx/dcss/dcss-dev.h | 195 +++++ drivers/gpu/drm/imx/dcss/dcss-dpr.c | 550 ++++++++++++++ drivers/gpu/drm/imx/dcss/dcss-drv.c | 181 +++++ drivers/gpu/drm/imx/dcss/dcss-dtg.c | 442 +++++++++++ drivers/gpu/drm/imx/dcss/dcss-kms.c | 322 ++++++++ drivers/gpu/drm/imx/dcss/dcss-kms.h | 52 ++ drivers/gpu/drm/imx/dcss/dcss-plane.c | 418 +++++++++++ drivers/gpu/drm/imx/dcss/dcss-scaler.c | 826 +++++++++++++++++++++ drivers/gpu/drm/imx/dcss/dcss-ss.c | 179 +++++ 20 files changed, 4326 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/display/imx/nxp,imx8mq-dcss.yaml create mode 100644 drivers/gpu/drm/imx/dcss/Kconfig create mode 100644 drivers/gpu/drm/imx/dcss/Makefile create mode 100644 drivers/gpu/drm/imx/dcss/dcss-blkctl.c create mode 100644 drivers/gpu/drm/imx/dcss/dcss-crtc.c create mode 100644 drivers/gpu/drm/imx/dcss/dcss-ctxld.c create mode 100644 drivers/gpu/drm/imx/dcss/dcss-dev.c create mode 100644 drivers/gpu/drm/imx/dcss/dcss-dev.h create mode 100644 drivers/gpu/drm/imx/dcss/dcss-dpr.c create mode 100644 drivers/gpu/drm/imx/dcss/dcss-drv.c create mode 100644 drivers/gpu/drm/imx/dcss/dcss-dtg.c create mode 100644 drivers/gpu/drm/imx/dcss/dcss-kms.c create mode 100644 drivers/gpu/drm/imx/dcss/dcss-kms.h create mode 100644 drivers/gpu/drm/imx/dcss/dcss-plane.c create mode 100644 drivers/gpu/drm/imx/dcss/dcss-scaler.c create mode 100644 drivers/gpu/drm/imx/dcss/dcss-ss.c -- 2.7.4 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
