Pull ARM SoC platform updates from Olof Johansson:
"New and/or improved SoC support for this release:
Marvell Berlin:
- Enable standard DT-based cpufreq
- Add CPU hotplug support
Freescale:
- Ethernet init for i.MX7D
- Suspend/resume support for i.MX6UL
Allwinner:
- Support for R8 chipset (used on NTC's $9 C.H.I.P board)
Mediatek:
- SMP support for some platforms
Uniphier:
- L2 support
- Cleaned up SMP support, etc.
plus a handful of other patches around above functionality, and a few
other smaller changes"
