Hi ,
i am using keystoneII (k2e) arch, I want to use the dma for data transfer through spi , so im using spi-davonci.c file , but in spi-davinci.c file
struct resource *r= platform_get_resource(pdev, IORESOURCE_DMA, 0);
here im getting r=NULL
similarly in r = platform_get_resource(pdev, IORESOURCE_DMA, 1); //here also im getting r=NULL;
because of that i am unable to request " davinci_spi_request_dma(dspi); " to get dmaRx and dmaTx channel , so that communication through spi is not done !
How to get resources for IORESOURCE_DMA type ??
is there im missing something ?
