Not exactly, 64 channel is maxium value, which IP supportted. There are difference instances in the same SOC. Some may only 31 dma channel, some may only 12, some have 64. Each channel have one irqs and one shared err irq. Ideally it should be property 'dma-channels' + 1. But not sure if schema can check such case.
