Hello, v2 of support for RDACM21 camera module in this series. 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.
