[PATCH v4 10/11] arm64: allwinner: a64: add dma controller references to spi nodes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The spi controller nodes omit the dma controller/channel references, add
it.

This does not yet enable DMA for SPI transfers, as the spi-sun6i driver
lacks support for DMA, but always uses PIO to the FIFO.
