Dear All,
this series adds support for dual-LVDS panel IDK-2121WR from Advantech: https://buy.advantech.eu/Displays/Embedded-LCD-Kits-High-Brightness/model-ID... Dual link support is very recent for R-Car Gen3, and I couldn't find much on dual link panels in the kernel either, therefore comments are very welcome to get this right.
The panel doesn't come with the EK874 kit, but it's advertised as supported, therefore this series adds a new dts file to support the configuration of the EK874 + IDK-2121WR.
Finally, this series depends on a fix that's still pending: https://patchwork.kernel.org/patch/11054755/
Thanks, Fab
