SubjectRe: [PATCHv5] dmaengine: Add support for BCM2835
Date


Group:

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,
