Hi,
Hi Jai, Thank you for the patches !
The first four patches in this series are miscellaneous fixes and improvements in the Cadence and TI CSI-RX drivers around probing, fwnode and link creation.
The last two patches add support for transmitting multiple pixels per clock on the internal bus between Cadence CSI-RX bridge and TI CSI-RX wrapper. As this internal bus is 32-bit wide, the maximum number of pixels that can be transmitted per cycle depend upon the format's bit width. Secondly, the downstream element must support unpacking of multiple pixels.
Thus we export a module function that can be used by the downstream driver to negotiate the pixels per cycle on the output pixel stream of the Cadence bridge.
