This series fixes two bugs: 1. When Cadence CSI2RX is used with an external DPHY controller, fix the programming sequence to configure the DPHY controller before starting streaming on the source 2. Fix a possible race condition in TI CSI2RX Shim driver when restarting DMA after stalling due to lack of buffers These fixes were originally posted in the multi-stream RFC series [1], but as these are unrelated and urgent, posting them separately now so they can get picked independently.
