My plan is it enable i2c4, uart0, and spi3 since those are the default on the pinctrl mux. I have tested uart0 and i2c4, but I am getting an error with SPI [ 2.423553] dw_spi_mmio 41b0000.spi: DMA init failed Not sure what is going on. I have the DMA controller enabled and it seems to be initalizing correctly. [ 0.732791] dw_axi_dmac_platform 4330000.dma-controller: DesignWare AXI DMA Controller, 8 channels Let me submit v3 so I can get some eyes on it.
