This patch adds the EDMA0/EDMA1 nodes used by audio peripherals. EDMA0 contains channels for: * ASRC0 * ESAI0 * SPDIF0 * SAI0, SAI1, SAI2, SAI3 EDMA1 contains channels for: * ASRC1 * SAI4, SAI5 See chapter Audio DMA Memory Maps (2.2.3) from i.MX8QXP RM [1] This patch is based on the dtsi file initially submitted by Teo Hall in i.MX NXP internal tree.
