Yes, I think so. I only used drivers new .device_prep_slave_sg() for SDHC DMA channel transfers up to now. Adding support for other peripherals would be good. With generic DMA DT bindings patch for this driver you can use dmas = <&dma0 26>; dma-names = "rx-tx"; in your sclpc@10100 DT node and then dma_request_slave_channel(&pdev->dev, "rx-tx") in the lpbfifo driver.
