Subject[PATCH v4 0/8] media: i2c: Add RDACM21 camera module
Date
Hello, this v4 follows discussion on how to better handle the initial
reverse channel amplitude and incorporate Geert's and Kieran suggestion
to use the value in millivolts instead of relying on a boolean property.

v4:
- Replace 'maxim-high-threshold' with 'maxim,initial-reverse-channel-mV'
- Increse delay when reading OV490 chip ID to give it a bit more time to
exit reset

v3:
https://patchwork.linuxtv.org/project/linux-media/list/?series=3657

Background in v1 cover letter:
https://www.spinics.net/lists/linux-renesas-soc/msg52886.html

I have tested on Eagle V3M with 4 RDACM21, but the whole point of
this series is to retain compatibility with RDACM20.

For this reason I have included 2 patches on top, not intended for merge
that re-propose DTS support for the MAXIM max9286 expansion board connected
to Salvator-X and add the newly introduced property to the DTS file.

Kieran, I know you have a working setup with RDACM20, the final two patches are
meant for ease your testing. Can you give this series a spin ?

Series based on latest renesas-drivers tag: renesas-drivers-2020-11-10-v5.10-rc3

If I get a confirmation this setup works on Salvator-X, I'll submit the new
property for inclusion to devicetree people, which I have left out at the
moment.

Thanks
