[v2,00/13] media: Add multiplexed support to R-Car CSI-2 and GMSL

Hello,
  this series is based on v9 of Tomi's
"v4l: subdev internal routing and streams":

With a few out-of-tree patches for GMSL support on top.

The series aims to
1) Plumb into Tomi's v4l2 subdev streams and routing to compare it with the
   previous implementations of multistream support
2) Add support for multiplexed streams to R-Car CSI-2 and MAX9286

For testing, I have re-proposed Niklas' patches on top of v4l2-ctl to control
routing and ported them to this last version. Support for state-based format
handling has been added on top. Two simple scripts to be deployed in vin-test
have been used to set routing and capture frames. Both are available at:
https://git.sr.ht/~jmondi_/v4l2-utils
https://git.sr.ht/~jmondi_/vin-test-multi

v2 contains changes to max9286 and R-Car CSI-2 while changes to support
routing VIN are still WIP and not included.

Tested on Eagle V3M by routing VC0 and VC1 to VIN0 and VIN3 respectively.

Thanks
   j

v1->v2:
- Rebase on Tomi's v9
- Break-out max9286 and CSI-2 mux support
- Add for_each_active_route() macro
- Add get_frame_desc to R-Car CSI-2
