[PATCH v3 0/6] media: adv748x: Implement dynamic routing support

[Jacopo Mondi <jacopo+renesas@jmondi.org>]

Hello,
   third iteration for adv748x dynamic selection of video source.

Please refer to v1 and v2 cover letter for more details:
https://patchwork.kernel.org/cover/10723971/
https://patchwork.kernel.org/cover/10749535/

This version includes comments from Laurent and Kieran, on patches 1/6 and
mostly on 6/6, which resulted in a better implementation. Thanks.

I have tested this on Ebisu E3 where I can capture HDMI and CVBS inputs from
TXA, and on Salvator-x M3-W where I can capture HDMI from TXA, and CVBS from
both TXA and TXB, but only when setting the number of CSI-2 data lanes to 2 in
DTS.

It remains unresolved how to dynamically negotiate the number of CSI-2 data
lanes to use between the video source and the CSI-2 receiver, which prevents
using AFE->TXA routing on all Gen3 SoC which use 4 CSI-2 data lanes.

The series is based on media tree master with the following series from
Niklas applied on top:
[PATCH v4 0/4] i2c: adv748x: add support for CSI-2 TXA to work in 1-, 2- and 4-lane mode

Branch available for testing at:

Thanks
