C865 DEV KIT uses a 4 bit I2S2 interface from the SM8250 for this task.
96Boards specification also calls for a MIPI-DSI interface to be routed to the High Speed Expansion connector.
Since the SM8250 has two MIPI-DSI interface for HDMI, two multiplexing devices (FSA644UCX) are used.
Only one interface, HDMI, or the Expansion MIPI-DSI can be active at one time. Control signal,
‘DIP_HDMI_SWITCH’, comes from DIP switch#16. When this signal is set to OFF state,
DIP_HDMI_SWITCH is logic HIGH ‘1’, MIPI-DSI signals will be routed to DSI-HDMI Bridge. When the
signal of DIP switch is set to ON state, DIP_HDMI_SWITCH is logic LOW ‘0’, MIPI-DSI signals will be
routed to the High Speed Expansion connector.
3.6.2 MIPI-DSI
C865 DEV KIT has 2x 4-lane MIPI_DSI interface. See below for details.
