The SoC couples an ARM Cortex A53 CPU with an Intel Movidius VPU. This driver is tested with the KMB EVM board which is the refernce baord for Keem Bay SOC. The SOC's display pipeline is as follows +--------------+ +---------+ +-----------------------+ |LCD controller| -> |Mipi DSI | -> |Mipi to HDMI Converter | +--------------+ +---------+ +-----------------------+ LCD controller and Mipi DSI transmitter are part of the SOC and mipi to HDMI converter is ADV7535 for KMB EVM board. The DRM driver is a basic KMS atomic modesetting display driver and has no 2D or 3D graphics.It calls into the ADV bridge driver at the connector level. Only 1080p resolution and single plane is supported at this time. The usecase is for debugging video and camera outputs. Device tree patches are under review here https://lore.kernel.org/linux-arm-kernel/20200708175020.194436-1-daniele.alessandrelli@linux.intel.com/T/ Changes since v1: - Removed redundant license text, updated license - Rearranged include blocks - renamed global vars and removed extern in c - Used upclassing for dev_private - Used drm_dev_init in drm device create (will be updated to use devm_drm_dev_alloc() in a separate patch later as kmb driver is currently developed on 5.4 kernel) - minor cleanups Anitha Chrisanthus (52): drm/kmb: Add support for KeemBay Display drm/kmb: Added id to kmb_plane drm/kmb: Set correct values in the LAYERn_CFG register drm/kmb: Use biwise operators for register definitions drm/kmb: Updated kmb_plane_atomic_check drm/kmb: Initial check-in for Mipi DSI drm/kmb: Set OUT_FORMAT_CFG register drm/kmb: Added mipi_dsi_host initialization drm/kmb: Part 1 of Mipi Tx Initialization drm/kmb: Part 2 of Mipi Tx Initialization drm/kmb: Use correct mmio offset from data book drm/kmb: Part3 of Mipi Tx initialization drm/kmb: Part4 of Mipi Tx Initialization drm/kmb: Correct address offsets for mipi registers drm/kmb: Part5 of Mipi Tx Intitialization drm/kmb: Part6 of Mipi Tx Initialization drm/kmb: Part7 of Mipi Tx Initialization drm/kmb: Part8 of Mipi Tx Initialization drm/kmb: Added ioremap/iounmap for register access drm/kmb: Register IRQ for LCD drm/kmb: IRQ handlers for LCD and mipi dsi drm/kmb: Set hardcoded values to LCD_VSYNC_START drm/kmb: Additional register programming to update_plane drm/kmb: Add ADV7535 bridge drm/kmb: Display clock enable/disable drm/kmb: rebase to newer kernel version drm/kmb: minor name change to match device tree drm/kmb: Changed MMIO size drm/kmb: Defer Probe drm/kmb: call bridge init in the very beginning drm/kmb: Enable MSS_CAM_CLK_CTRL for LCD and MIPI drm/kmb: Set MSS_CAM_RSTN_CTRL along with enable drm/kmb: Mipi DPHY initialization changes drm/kmb: Fixed driver unload drm/kmb: Added LCD_TEST config drm/kmb: Changes for LCD to Mipi drm/kmb: Update LCD programming to match MIPI drm/kmb: Changed name of driver to kmb-drm drm/kmb: Mipi settings from input timings drm/kmb: Enable LCD interrupts drm/kmb: Enable LCD interrupts during modeset drm/kmb: Don’t inadvertantly disable LCD controller drm/kmb: SWAP R and B LCD Layer order drm/kmb: Disable ping pong mode drm/kmb: Do the layer initializations only once drm/kmb: disable the LCD layer in EOF irq handler drm/kmb: Initialize uninitialized variables drm/kmb: Added useful messages in LCD ISR kmb/drm: Prune unsupported modes drm/kmb: workaround for dma undeflow issue drm/kmb: Get System Clock from SCMI drm/kmb: work around for planar formats Edmund Dea (7): drm/kmb: Cleanup probe functions drm/kmb: Revert dsi_host back to a static variable drm/kmb: Initialize clocks for clk_msscam, clk_mipi_ecfg, & clk_mipi_cfg. drm/kmb: Remove declaration of irq_lcd/irq_mipi drm/kmb: Enable MIPI TX HS Test Pattern Generation drm/kmb: Write to LCD_LAYERn_CFG only once drm/kmb: Cleaned up code drivers/gpu/drm/Kconfig | 2 + drivers/gpu/drm/Makefile | 1 + drivers/gpu/drm/kmb/Kconfig | 12 + drivers/gpu/drm/kmb/Makefile | 2 + drivers/gpu/drm/kmb/kmb_crtc.c | 226 +++++ drivers/gpu/drm/kmb/kmb_crtc.h | 41 + drivers/gpu/drm/kmb/kmb_drv.c | 809 ++++++++++++++++ drivers/gpu/drm/kmb/kmb_drv.h | 176 ++++ drivers/gpu/drm/kmb/kmb_dsi.c | 1927 +++++++++++++++++++++++++++++++++++++++ drivers/gpu/drm/kmb/kmb_dsi.h | 370 ++++++++ drivers/gpu/drm/kmb/kmb_plane.c | 518 +++++++++++ drivers/gpu/drm/kmb/kmb_plane.h | 124 +++ drivers/gpu/drm/kmb/kmb_regs.h | 738 +++++++++++++++ 13 files changed, 4946 insertions(+) create mode 100644 drivers/gpu/drm/kmb/Kconfig create mode 100644 drivers/gpu/drm/kmb/Makefile create mode 100644 drivers/gpu/drm/kmb/kmb_crtc.c create mode 100644 drivers/gpu/drm/kmb/kmb_crtc.h create mode 100644 drivers/gpu/drm/kmb/kmb_drv.c create mode 100644 drivers/gpu/drm/kmb/kmb_drv.h create mode 100644 drivers/gpu/drm/kmb/kmb_dsi.c create mode 100644 drivers/gpu/drm/kmb/kmb_dsi.h create mode 100644 drivers/gpu/drm/kmb/kmb_plane.c create mode 100644 drivers/gpu/drm/kmb/kmb_plane.h create mode 100644 drivers/gpu/drm/kmb/kmb_regs.h
