Hi, my platform has a DIP switch controlled multiplexer for MIPI DSI output signals. One output has a TI SN65DSI84 (LVDS) and the other output has a TI SN65DSI86 (eDP) attached to it. The Multiplexer status can be read back from a GPIO. The GPIO is also IRQ capable, so it would be possible to support hotplug additionally later on. My initial idea was to create a DRM multiplexer bridge driver which (depending on the input GPIO) allows only one output to be enabled. Unfortunately ti- sn65dsi86.c driver expects a DSI host on remote node 0 (see ti_sn_attach_host and ti_sn_bridge_parse_dsi_host), so it does not work. ti-sn65dsi83.c just requires a drm_bridge. What is the best approach for this? I currently see two approaches: * Create an explicit DSI/DRM multiplexer bridge driver which registers itself as DSI host * Create a DRM multiplexer bridge (only). But this needs to remove the DSI device registration from ti-sn65dsi86.c I am aware that DSI support is suboptimal, so I'm not sure which approach on the TI bridge drivers is the correct one and needs to be considered as given. Any ideas?
