From: Jamie Iles Date: Fri, 21 Jan 2011 14:11:55 +0000 (+0000) Subject: avr32: at32ap700x: specify DMA src and dst masters X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=4aa5f366431fe;p=linux-beck.git avr32: at32ap700x: specify DMA src and dst masters Now that the dw_dmac DMA driver supports configurable source and destination masters we need to specify which ones to use. This was previously hardcoded to 0 and 1 respectively in the driver.
