Subject: [PATCH 1/3] arm64: dts: juno: Add dma-ranges property
Date: Wed, 18 Jan 2017 12:12:50 +0000	[thread overview]
Message-ID: <74595d6d866518db7cfabc39b4cf9b54d3be9bde.1484741104.git.robin.murphy@arm.com> (raw)

The interconnects around Juno have a 40-bit address width, and DMA
masters have no restrictions beyond their own individual limitations.
Describe this to ensure that DT-based DMA masks get set up correctly
for all devices capable of 40-bit addressing.

Signed-off-by: Robin Murphy <robin.murphy@arm.com>

These apply on top of Sudeep's for-next/updates/juno branch, which
supercedes the .dtsi cleanup I had locally to make this one work.

Robin.
