Subject: [PATCH 0/3] Add DSI Port B input support for LT9611 HDMI bridge

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.
