[PATCH v5 0/8] media: i2c: Add RDACM21 camera module

[Jacopo Mondi]

Hello,
   this v5 mostly changes how the rdacm21 driver handles writes to the
OV490 chip by handling the 'high' part of the sensor register through an
helper function as suggested by Kieran and Laurent.

The diff is available at:
https://paste.debian.net/1172700/

Minor fixes in patches subjects and in bindings as reported by Sergei and
Kieran.

Bindings have now been sent to DT people now that they've been reviewed
by Kieran.

v4: https://patchwork.linuxtv.org/project/linux-media/list/?series=3847
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 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

Thanks
  j
