This is a request to augment with comments the DREQ explanation in the Broadcom BCM2835 pdf on page 61 regarding DMA peripheral mapping. Specifically, how to identify a pin on the 26 pin header to use for DMA reads. More specifically, if a clock signal, like GPCLK0 is output to the peripheral device (like an A/D converter) how we specify PERMAP in the DMA TI register. Your users would be infinitely grateful. thank you, -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
