Actually, I changed the name several times and in the end I sticked to https://github.com/raspberrypi/linux/issues/22 but if you think it is better to use BCM2835 I am happy to agree with you and change it. > Upstream only uses device tree for BCM2835.

I would like to, but it only supports cyclic DMA. Should I send it upstream anyway? In case you are interested: https://github.com/koalo/linux/blob/rpi-3.8.y-asocdev/drivers/dma/bcm2708-dmaengine.c > I'll take a look at the actual patch content later.
