Subject: [PATCH 1/2] BCM2835: Add dmaengine driver to device tree

From: [email-masked] (Florian Meier)
Date: Mon, 13 Jan 2014 12:11:43 +0100

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.
