Subject: [PATCH 1/2] BCM2835: Add dmaengine driver to device tree
Date: Mon, 13 Jan 2014 12:11:43 +0100 [thread overview]
Message-ID: <52D3C9EF.1030901@koalo.de> (raw)
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.
