Hi,

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.
