Subject: ARM: bcm2835: add dmaengine driver to device tree
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=890723395fc73e8dfb3b7da0f5717750cfae83a0;p=linux-beck.git

ARM: bcm2835: add dmaengine driver to device tree

This adds the definitions for the BCM2835 dmaengine driver
to the device tree. The dma-channel-mask is currently
fixed. Later it should be set via the firmware.
