How to enable SPI-DMA on 410c with spi0 (android system)?


#1

Hi,
i have read document “lm80-p0436-5_peripherals_programming_guide”, and i found the setting is already exist in device tree,
but with further tracing kernel source code, i found spi message still using FIFO mode to device, due to function platform default master driver still not using dma setting.
i am using spi_sync for read out data from my spi device, is anything i misunderstanding or spi-dma is not support on 410c with this OS ?
regards
Gary
