From 193d00a2b35ee3353813b4006a18131122087205 Mon Sep 17 00:00:00 2001 From: Robin Murphy Date: Wed, 18 Jan 2017 12:12:50 +0000 Subject: [PATCH] arm64: dts: juno: add dma-ranges property 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.
