Subject: [PATCH] arm64: dts: renesas: Add /soc dma-ranges

From: [email-masked]
Date: Sat, 7 Sep 2019 18:16:34 +0200

From: Marek Vasut <[email-masked]>

Add dma-ranges property into /soc node to describe the DMA capabilities
of the bus. This is currently needed to translate PCI DMA ranges, which
are limited to 32bit addresses.
