drm/simpledrm: Use fbdev defaults for shadow buffering

2022-05-03T14:04:22Z

Don't select shadow buffering for the fbdev console explicitly. The fbdev emulation's heuristic will enable it for any framebuffer with .dirty callback.

drm/format-helper: Rename drm_fb_xrgb8888_to_mono_reversed()

2022-03-17T11:29:40Z

There is no "reversed" handling in drm_fb_xrgb8888_to_mono_reversed(): the function just converts from color to grayscale, and reduces the number of grayscale levels from 256 to 2 (i.e. brightness 0-127 is mapped to 0, 128-255 to 1). All "reversed" handling is done in the repaper driver, where this function originated. Hence make this clear by renaming drm_fb_xrgb8888_to_mono_reversed() to drm_fb_xrgb8888_to_mono(), and documenting the black/white pixel mapping.

drm/tiny: Add MIPI DBI compatible SPI driver

2022-02-28T09:29:33Z

Add a driver that will work with most MIPI DBI compatible SPI panels. This avoids adding a driver for every new MIPI DBI compatible controller that is to be used by Linux. The 'compatible' Device Tree property with a '.bin' suffix will be used to load a firmware file that contains the controller configuration. Example (driver will load sainsmart18.bin): display@0 { compatible = "sainsmart18", "panel-mipi-dbi-spi"; ... }; v5: - kconfig: s/DRM_KMS_CMA_HELPER/DRM_GEM_CMA_HELPER/ (Sam) - kconfig: Add select VIDEOMODE_HELPERS (Sam) - kconfig: Add wiki url in the description (Sam) - Split out and use of_get_drm_panel_display_mode()(Sam) - Only use the first compatible to look for a firmware file since the binding mandates 2 compatibles. - Make having a firmware file mandatory so we can print an error message if it's missing to improve the user experience. It's very unlikely that a controller doesn't need to be initialized and if it doesn't, it's possible to have a firmware file containing only a DCS NOP. v4: - Move driver to drm/tiny where the other drivers of its kind are located. The driver module will not be shared with a future DPI driver after all. v3: - Move properties to DT (Maxime) - The MIPI DPI spec has optional support for DPI where the controller is configured over DBI. Rework the command functions so they can be moved to drm_mipi_dbi and shared with a future panel-mipi-dpi-spi driver v2: - Drop model property and use compatible instead (Rob) - Add wiki entry in MAINTAINERS Acked-by: Maxime Ripard Reviewed-by: Sam Ravnborg Signed-off-by: Noralf Trønnes Signed-off-by: Maxime Ripard Link: https://patchwork.freedesktop.org/patch/msgid/20220227124713.39766-6-noralf@tronnes.org

drm/simpledrm: Add "panel orientation" property on non-upright mounted LCD panels

2022-02-23T12:17:50Z

Some devices use e.g. a portrait panel in a standard laptop casing made for landscape panels. efifb calls drm_get_panel_orientation_quirk() and sets fb_info.fbcon_rotate_hint to make fbcon rotate the console so that it shows up-right instead of on its side. When switching to simpledrm the fbcon renders on its side. Call the drm_connector_set_panel_orientation_with_quirk() helper to add a "panel orientation" property on devices listed in the quirk table, to make the fbcon (and aware userspace apps) rotate the image to display properly.
