Subject: [PATCH v2 6/7] ARM: dts: keystone: Use dma-ranges property
Date: Thu, 27 Feb 2014 16:17:51 -0500	[thread overview]
Message-ID: <1393535872-20915-7-git-send-email-santosh.shilimkar@ti.com> (raw)
In-Reply-To: <1393535872-20915-1-git-send-email-santosh.shilimkar-l0cyMroinI0@public.gmane.org>

From: Grygorii Strashko <grygorii.strashko-l0cyMroinI0@public.gmane.org>

The dma-ranges property has to be specified per bus and has format:
 < DMA addr > - Base DMA address for Bus (Bus format 32-bits)
 < CPU addr > - Corresponding base CPU address (CPU format 64-bits)
 < DMA range size > - Size of supported DMA range
