Merge tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM device-tree updates from Olof Johansson:
"Business as usual -- the bulk of our changes are to devicetree files
with new hardware support, new SoCs and platforms, and new board
types.
New SoCs/platforms:
- Raspberry Pi Compute Module (CM1) and IO board
- i.MX6SSL from NXP
- Renesas RZ/N1D SoC (R9A06G032), Dual Cortex-A7 with Ethernet, CAN
and PLC interfaces
- TI AM654 SoC, Quad Cortex-A53, safety subsystem with Cortex-R5
controllers, communication and PRU subsystem and lots of other
interfaces (PCIe, USB3, etc).
New boards and systems:
- Several Atmel at91-based boards from Laird
- Marvell Armada388-based Helios4 board from SolidRun
- Samsung Aires-based phones (s5pv210)
- Allwinner A64-based Pinebook laptop
In addition to the above, there's the usual amount of new devices
described on existing platforms, fixes and tweaks and new minor
variants of boards/platforms"
