Hi, I think this seems to be a known use case for industrial these days with i.mx8m. The host DSI would configure with two bridges one for DSI to LVDS (SN65DSI83) and another for DSI to HDMI Out (ADV7535). Technically we can use only one bridge at a time as host DSI support single out port. So we can have two separate device tree files for LVDS and HDMI and load them static. But, one of the use cases is to support both of them in single dts, and - Turn On LVDS (default) - Turn Off LVDS then Turn On HDMI when cable plug-in. The HDMI event can be detected via some HDMI-INT GPIO on-board design. The possible solution, I'm thinking of adding LVDS on port 1, HDMI on port 2 in the DSI host node, and trying to attach the respective bridge based on HDMI-INT like repeating the bridge attachment cycle based on the HDMI-INT. Can it be possible to do bridge attachment at runtime? something like a bridge hotplug event? or any other possible solutions? Any suggestions? Thanks, Jagan.
