Add support for Saef Technology Limited SFTO340XC LCD panel. Add alongside the number of lanes configuration in the ili9881c driver as the board on my desc use the panel with only two lanes.
Faced an issue with panel-common binding. Wrote a fix (first patch) but not sure it is the right one. If someone from dt tree could take a look, it would be nice. Signed-off-by: Kory Maincent <kory.mainc...@bootlin.com> --- Changes in v2: - Add new patch trying to fix panel-common binding. - Read the data-lanes parameter from the port endpoint and use drm_of_get_data_lanes_count instead of of_property_read_u32. - Link to v1: https://lore.kernel.org/r/20250408-feature_sfto340xc-v1-0-f303d1b9a...@bootlin.com --- Kory Maincent (5): dt-bindings: display: panel: Fix port binding dt-bindings: display: panel: ili9881c: Add data-lanes property drm/panel: ilitek-ili9881c: Add support for two-lane configuration dt-bindings: ili9881c: Add Saef SFTO340XC support drm: panel: Add Saef SFTO340XC LCD panel .../bindings/display/panel/ilitek,ili9881c.yaml | 21 ++ .../bindings/display/panel/panel-common.yaml | 2 +- drivers/gpu/drm/panel/panel-ilitek-ili9881c.c | 265 ++++++++++++++++++++- 3 files changed, 285 insertions(+), 3 deletions(-) --- base-commit: bef4f1156b74721b7d111114538659031119b6f2 change-id: 20250129-feature_sfto340xc-d2b25a5b5748 Best regards, -- Köry Maincent, Bootlin Embedded Linux and kernel engineering https://bootlin.com
