Xilinx already received such comments, so finally please learn them. Drop the example. Best regards, Krzysztof

Add compatible string "amd,versal2-dma-1.0" to support AMD Versal Gen 2 platform. AMD Versal Gen 2 has 8 LPD DMA IPs in PS that can be used as general purpose DMAs which is designed to support memory to memory and memory to IO buffer transfer. Versal Gen 2 DMA IP has different interrupt register offset. Add example binding documentation for the newly added compatible string.
