  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.
