These patches add Display-Port driver on SnapDragon/msm hardware. This series also contains device-tree bindings for msm DP driver. It also contains Makefile and Kconfig changes to compile msm DP driver.
The block diagram of DP driver is shown below: +-------------+ |DRM FRAMEWORK| +------+------+ | +----v----+ | DP DRM | +----+----+ | +----v----+ +------------+| DP +----------++------+ + +---+| DISPLAY |+---+ | | | + +-+-----+-+ | | | | | | | | | | | | | | | | | | | | | | | | v v v v v v v +------+ +------+ +---+ +----+ +----+ +---+ +-----+ | DP | | DP | |DP | | DP | | DP | |DP | | DP | |PARSER| | HPD | |AUX| |LINK| |CTRL| |PHY| |POWER| +--+---+ +---+--+ +---+ +----+ +--+-+ +-+-+ +-----+ | | | +--v---+ +v-----v+ |DEVICE| | DP | | TREE | |CATALOG| +------+ +---+---+ | +---v----+ |CTRL/PHY| | HW | +--------+ Changes in v7: - Modify cover letter description and fix title. - Introduce dp-controller.yaml for common bindings across SOC - Rename dp-sc7180.yaml to dp-controller-sc7180.yaml for SC7180 bindings - Rename compatible string to qcom,sc7180-dp - Add assigned-clocks and assigned-clock-parents properties in bindings - Remove redundant code from driver - Extend series to include HPD detection logic Changes in v8: - Add MDSS AHB clock in bindings - Replace mode->vrefresh use with drm_mode_vrefresh API - Remove redundant aux config code from parser and aux module - Assign default max lanes if data-lanes property is not available - Fix use-after-free during DP driver remove - Unregister hardware clocks during driver cleanup Changes in v9: - Drop YAML bindings change from the series - Use assigne-clock-parents property and remove clk_set_parent use from code - Access register address space without name - Fix DP register dump utility - Disable DP clocks after vsync generated - Avoid 64-bit modulo operation - Drop any unused code and fix function proptotyes to avoid W=1 warnings - Drop DRM_MSM_DP_10NM_PLL config as only 10nm PLL is available Changes in v10: - Fix help description of Kconfig entry Chandan Uddaraju (4): dt-bindings: msm/dp: add bindings of DP/DP-PLL driver for Snapdragon drm: add constant N value in helper file drm/msm/dp: add displayPort driver support drm/msm/dp: add support for DP PLL driver Jeykumar Sankaran (1): drm/msm/dpu: add display port support in DPU Tanmay Shah (1): drm/msm/dp: Add Display Port HPD feature drivers/gpu/drm/i915/display/intel_display.c | 2 +- drivers/gpu/drm/msm/Kconfig | 9 + drivers/gpu/drm/msm/Makefile | 14 + drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.c | 27 +- .../drm/msm/disp/dpu1/dpu_encoder_phys_vid.c | 8 + drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c | 83 +- drivers/gpu/drm/msm/dp/dp_aux.c | 510 +++++ drivers/gpu/drm/msm/dp/dp_aux.h | 29 + drivers/gpu/drm/msm/dp/dp_catalog.c | 1030 ++++++++++ drivers/gpu/drm/msm/dp/dp_catalog.h | 104 + drivers/gpu/drm/msm/dp/dp_ctrl.c | 1693 +++++++++++++++++ drivers/gpu/drm/msm/dp/dp_ctrl.h | 35 + drivers/gpu/drm/msm/dp/dp_display.c | 1017 ++++++++++ drivers/gpu/drm/msm/dp/dp_display.h | 31 + drivers/gpu/drm/msm/dp/dp_drm.c | 168 ++ drivers/gpu/drm/msm/dp/dp_drm.h | 18 + drivers/gpu/drm/msm/dp/dp_hpd.c | 69 + drivers/gpu/drm/msm/dp/dp_hpd.h | 79 + drivers/gpu/drm/msm/dp/dp_link.c | 1214 ++++++++++++ drivers/gpu/drm/msm/dp/dp_link.h | 132 ++ drivers/gpu/drm/msm/dp/dp_panel.c | 486 +++++ drivers/gpu/drm/msm/dp/dp_panel.h | 95 + drivers/gpu/drm/msm/dp/dp_parser.c | 269 +++ drivers/gpu/drm/msm/dp/dp_parser.h | 138 ++ drivers/gpu/drm/msm/dp/dp_pll.c | 99 + drivers/gpu/drm/msm/dp/dp_pll.h | 61 + drivers/gpu/drm/msm/dp/dp_pll_10nm.c | 917 +++++++++ drivers/gpu/drm/msm/dp/dp_pll_private.h | 98 + drivers/gpu/drm/msm/dp/dp_power.c | 373 ++++ drivers/gpu/drm/msm/dp/dp_power.h | 103 + drivers/gpu/drm/msm/dp/dp_reg.h | 517 +++++ drivers/gpu/drm/msm/msm_drv.c | 2 + drivers/gpu/drm/msm/msm_drv.h | 59 +- include/drm/drm_dp_helper.h | 1 + 34 files changed, 9471 insertions(+), 19 deletions(-) create mode 100644 drivers/gpu/drm/msm/dp/dp_aux.c create mode 100644 drivers/gpu/drm/msm/dp/dp_aux.h create mode 100644 drivers/gpu/drm/msm/dp/dp_catalog.c create mode 100644 drivers/gpu/drm/msm/dp/dp_catalog.h create mode 100644 drivers/gpu/drm/msm/dp/dp_ctrl.c create mode 100644 drivers/gpu/drm/msm/dp/dp_ctrl.h create mode 100644 drivers/gpu/drm/msm/dp/dp_display.c create mode 100644 drivers/gpu/drm/msm/dp/dp_display.h create mode 100644 drivers/gpu/drm/msm/dp/dp_drm.c create mode 100644 drivers/gpu/drm/msm/dp/dp_drm.h create mode 100644 drivers/gpu/drm/msm/dp/dp_hpd.c create mode 100644 drivers/gpu/drm/msm/dp/dp_hpd.h create mode 100644 drivers/gpu/drm/msm/dp/dp_link.c create mode 100644 drivers/gpu/drm/msm/dp/dp_link.h create mode 100644 drivers/gpu/drm/msm/dp/dp_panel.c create mode 100644 drivers/gpu/drm/msm/dp/dp_panel.h create mode 100644 drivers/gpu/drm/msm/dp/dp_parser.c create mode 100644 drivers/gpu/drm/msm/dp/dp_parser.h create mode 100644 drivers/gpu/drm/msm/dp/dp_pll.c create mode 100644 drivers/gpu/drm/msm/dp/dp_pll.h create mode 100644 drivers/gpu/drm/msm/dp/dp_pll_10nm.c create mode 100644 drivers/gpu/drm/msm/dp/dp_pll_private.h create mode 100644 drivers/gpu/drm/msm/dp/dp_power.c create mode 100644 drivers/gpu/drm/msm/dp/dp_power.h create mode 100644 drivers/gpu/drm/msm/dp/dp_reg.h base-commit: 418eda8f3fe292782c150266d693d55d284c0c98 -- The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum, a Linux Foundation Collaborative Project _______________________________________________ Freedreno mailing list Freedreno@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/freedreno
