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 v12: -- Add support of pm ops in display port driver -- Clear bpp depth bits before writing to MISC register -- Fix edid read Previous change log: https://lkml.kernel.org/lkml/20200818051137.21478-1-tanmay@xxxxxxxxxxxxxx/ 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 | 535 ++++++ drivers/gpu/drm/msm/dp/dp_aux.h | 30 + drivers/gpu/drm/msm/dp/dp_catalog.c | 1045 ++++++++++ drivers/gpu/drm/msm/dp/dp_catalog.h | 105 + 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 | 1046 ++++++++++ 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 | 267 +++ 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 | 930 +++++++++ drivers/gpu/drm/msm/dp/dp_pll_private.h | 89 + 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 | 518 +++++ 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, 9545 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: d012a7190fc1fd72ed48911e77ca97ba4521bccd -- The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum, a Linux Foundation Collaborative Project _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
