Subject: linux-next: build warnings in Linus' tree

Hi all,

Today's linux-next build of Linus' tree (arm multi_v7_defconfig) produced
these warnings:

arch/arm/boot/dts/bcm2835-rpi.dtsi:18.4-15: Warning (dma_ranges_format): /soc/firmware:dma-ranges: empty "dma-ranges" property but its #address-cells (2) differs from /soc (1)

I have no idea what caused this :-(

A dtc update combined with changes that landed in the above file after
I tested and fixed the new warnings.

Here's the commit for reference: https://lkml.org/lkml/2020/3/26/445
