This v2 shifted a bit more to rework bridge timing support. While
my use case mainly cares about complete bus flag support, it seems
to me that bus timings have ended up to be more complex than

Hello everyone,
I've long thought the V4L2 fwnode framework requires some work (it's buggy
and it does not adequately serve common needs). This set should address in
particular these matters:

framework was not able to use su
Allow specifying the bus type explicitly for MIPI D-PHY, parallel and

support parallel and
The continuous clock flag was only set if there was a clock or data lanes.
This isn't needed as such a configuration is invalid to begin with. Always
set the continuous clock flag if the non-continuous property is not found.
