The current driver only supports Port A or dual-port (A+B) mode, but some boards like RubikPi3 connect DSI to Port B only. This series adds support for using DSI Port B as the input source by utilizing the existing ports mechanism in devicetree: - port@0 corresponds to LT9611 DSI Port A input - port@1 corresponds to LT9611 DSI Port B input The driver detects which ports are populated and configures the hardware accordingly. When only port@1 is present, it configures port swap (register 0x8303 bit 6) and byte_clk source (register 0x8250 bit 3:2) for Port B operation. Signed-off-by: Hongyang Zhao --- Changes in v2: - Use ports mechanism instead of boolean property - port@0 corresponds to LT9611 Port A, port@1 to Port B - Driver detects which port is populated and configures accordingly - Link to v1: https://lore.kernel.org/r/20260127-rubikpi-next-20260116-v1-0-0286c75150c5@thundersoft.com --- Hongyang Zhao (3): dt-bindings: display: lt9611: Support single Port B input drm/bridge: lt9611: Add support for single Port B input arm64: dts: qcom: qcs6490-rubikpi3: Use lt9611 DSI Port B .../bindings/display/bridge/lontium,lt9611.yaml | 15 +++++-- .../boot/dts/qcom/qcs6490-thundercomm-rubikpi3.dts | 8 ++-- drivers/gpu/drm/bridge/lontium-lt9611.c | 46 +++++++++++++++------- 3 files changed, 47 insertions(+), 22 deletions(-) --- base-commit: 46fe65a2c28ecf5df1a7475aba1f08ccf4c0ac1b change-id: 20260127-rubikpi-next-20260116-99c1dbea50e4 Best regards, -- Hongyang Zhao
