The LT9611 HDMI bridge has two DSI input ports (Port A and Port B). 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 selecting DSI Port B as the input source: - Patch 1 adds the dt-bindings documentation for the new property - Patch 2 implements the driver support for Port B input selection - Patch 3 enables this feature on the RubikPi3 board The implementation configures port swap (register 0x8303 bit 6) and byte_clk source (register 0x8250 bit 3:2) when Port B is selected.
