Merge tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM DT updates from Olof Johansson:
"Device tree contents continue to be the largest branches we submit.
This time around, some of the contents worth pointing out is:
New SoC platforms:
- Freescale i.MX 7Solo
- Broadcom BCM23550
- Cirrus Logic EP7209 and EP7211 (clps711x platforms)_
- Hisilicon HI3519
- Renesas R8A7792
Some of the other delta that is sticking out, line-count wise:
- Exynos moves of IP blocks under an SoC bus, which causes a large
delta due to indentation changes
- a new Tegra K1 board: Apalis
- a bunch of small updates to many Allwinner platforms; new hardware
support, some cleanup, etc"
