The first supported panel is the DLC DLC0697 1080x1920@60Hz MIPI DSI panel. Changes in v4: - Use active-low reset GPIO semantics: define reset-gpios as active-low in DT and use hold=1/drop=0 in the driver (Dmitry Baryshkov) - Replace raw DCS writes with proper helpers: mipi_dsi_dcs_set_tear_on_multi(), MIPI_DCS_SET_CABC_MIN_BRIGHTNESS, MIPI_DCS_WRITE_CONTROL_DISPLAY, MIPI_DCS_WRITE_POWER_SAVE (Dmitry Baryshkov) - Use mipi_dsi_dcs_set_display_brightness_multi() with 0x1fff initial brightness (Dmitry Baryshkov) - Move MIPI_DSI_MODE_LPM to probe(), drop toggling in on()/off() (Dmitry Baryshkov) - Express .clock as arithmetic expression for clarity (Dmitry Baryshkov) - Update panel physical dimensions width_mm/height_mm (Dmitry Baryshkov) - Link to v3: https://lore.kernel.org/r/20260624-ili7807s-v3-0-ddf37052a289@oss.qualcomm.com Changes in v3: - Return devm_mipi_dsi_attach() directly (Neil Armstrong) - Link to v2: https://lore.kernel.org/all/20260618-ili7807s-v2-0-b3f0c109b102@oss.qualcomm.com/ Changes in v2: - Drop MAINTAINERS entry (Dmitry Baryshkov) - Use devm_drm_panel_add() instead of drm_panel_add() to avoid manual drm_panel_remove() in the error path (Dmitry Baryshkov) - Rework backlight: call drm_panel_of_backlight() first and fall back to creating a DCS backlight device if panel->backlight is still NULL (Dmitry Baryshkov) - Remove backlight-en-gpios from the binding (Dmitry Baryshkov) - Fix mode_flags LPM not restored on backlight update error path - Link to v1 : https://lore.kernel.org/all/20260518-ili7807s-panel-v1-0-d7b048163b1c@oss.qualcomm.com/ --- Arpit Saini (2): dt-bindings: display: panel: add Ilitek ILI7807S panel controller drm/panel: add Ilitek ILI7807S panel driver .../bindings/display/panel/ilitek,ili7807s.yaml | 71 +++++ drivers/gpu/drm/panel/Kconfig | 12 + drivers/gpu/drm/panel/Makefile | 1 + drivers/gpu/drm/panel/panel-ilitek-ili7807s.c | 285 +++++++++++++++++++++ 4 files changed, 369 insertions(+) --- base-commit: 4e5dfb7c84012007c3c7061126491bbc92d71bf1 change-id: 20260615-ili7807s-panel Best regards, -- Arpit Saini
