Subject[PATCH/RFC 00/12] Add dual-LVDS panel support to EK874
Date
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-IDK-2121WR-K2FHA2E.htm
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
