| |
Some sai only connect one direction dma (rx/tx) in SOC. For example: imx8qxp sai5 only connect tx dma channel. So allow only one "rx" or "tx" for dma-names.
Remove description under dmas because no user use index to get dma channel. All user use 'dma-names' to get correct dma channel. dma-names already in 'required' list.
