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.
Laurent,
it appears that Rob has been busy converting the dt-bindings relevant to this series, and his changes are now found in linux-next. Most notably Documentation/devicetree/bindings/display/panel/panel-lvds.txt has now become Documentation/devicetree/bindings/display/panel/lvds.yaml
You have already taken patch: https://patchwork.kernel.org/patch/11072749/
as such the patch I am sending you is still related to: Documentation/devicetree/bindings/display/panel/panel-lvds.txt
Patch "dt-bindings: display: Add bindings for Advantech IDK-2121WR" is still assuming the format is .txt, as I am not too sure about what the protocol is in this case? Shall we take this patch and convert it later to .yaml or shall I convert it to .yaml straight away?
Please, let me know what's the best course of action.
