Hello, This series adapts the R-Car CSI-2 receiver recovery logic to match updates in the datasheet. The later datasheets recommend that the whole video pipeline shall be stopped if an transmission error is detected instead of just restarting the CSI-2 receiver. This is tested on M3-N and a fault is injected by quickly removing and re-inserting the HDMI cable while streaming. This method does not always hit and is time consuming. To consistently prove correctness of handling a fake fault was introduced by a HACK and a debugfs entry.
