From: Conor Dooley conor.dooley@microchip.com
The DMAC on the k210 has a non standard interrupt configuration, which leads to dtbs_check warnings:
k210_generic.dtb: dma-controller@50000000: interrupts: [[27], [28], [29], [30], [31], [32]] is too long
From schema: linux/Documentation/devicetree/bindings/dma/snps,dw-axi-dmac.yaml
Update the binding to use a custom compatible to avoid the warning.
