Copy the board device tree files from linux v5.14. On top of the v5.14 dtbs the changes of these two patches are included here which are needed for u-boot: https://lore.kernel.org/linux-devicetree/20210831134013.1625527-7-michael@wa... https://lore.kernel.org/linux-devicetree/20210831134013.1625527-8-michael@wa...
At the time of this writing the patches are still pending but already have Reviewed-by tags.
