In some cases observed during ESD tests, the TI SN65DSI83 cannot recover from errors by itself. A full restart of the bridge is needed in those cases to have the bridge output LVDS signals again.
I have seen the bridge being flaky sometimes, do you have any more details of what is going on when this irrecoverable error occurs ?
The TI SN65DSI83 has some error detection capabilities. Introduce an error recovery mechanism based on this detection. The errors detected are signaled through an interrupt. On system where this interrupt is not available, the driver uses a polling monitoring fallback to check for errors. When an error is present, the recovery process is launched. Restarting the bridge needs to redo the initialization sequence. This initialization sequence has to be done with the DSI data lanes driven in LP11 state. In order to do that, the recovery process resets the entire pipeline.
+CC Michael regarding the LP11 part , I think there was some development to switch lanes into LP11 mode on request ?
