Subject: [PATCH v2 03/11] dt-bindings: soc/fsl: Update reserved memory binding for QBMan
Date: Wed, 19 Apr 2017 16:48:42 -0400	[thread overview]
Message-ID: <1492634930-10765-4-git-send-email-roy.pledge@nxp.com> (raw)
In-Reply-To: <1492634930-10765-1-git-send-email-roy.pledge@nxp.com>

Updates the QMan and BMan device tree bindings for reserved memory
nodes. This makes the reserved memory allocation compatiable with
the shared-dma-pool usage.

Signed-off-by: Roy Pledge <roy.pledge@nxp.com>
