[PATCH v3 0/7] media: i2c: Add support for RDACM21 camera module

From: Jacopo Mondi
Date: Fri Oct 16 2020 - 06:06:57 EST


v3:
- small update in 3/7 as suggested by Kieran and Sergei
- Add Kieran's tag to 3/7 and 4/7

Copy of v2 copy letter for reference:

Patch [1/7] introduces the camera module driver.
Only change compared to v1:
- Increase pixel clock to 55MHz

>From [2/7] to [5/7] there's a proposal of a possible way to support
both RDACM20 and RDACM21 with the same deserializer driver.
See v1 cover letter for details:
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 ?
For your convenience I pushed a branch
git://jmondi.org/linux #gmsl/jmondi/renesas-drivers-2020-10-13-v5.9/rdacm21_high-threshold

Series based on latest renesas-drivers tag: renesas-drivers-2020-10-13-v5.9

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
