Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC platform updates from Arnd Bergmann:
"SoC platform changes (arch/arm/mach-*). This merge window, the bulk is
for a few platforms:
- Andres Färber adds initial support for the Actions Semi S500 (aka
'owl') platform, a close relative of the S900 platform he adds for
arm64.
- in mach-omap2, we remove more legacy code
- Rockchips gains support for the RV1108 SoC designed for camera
applications.
- For Atmel, we gain support for MMU-less SoCs (SAME70/V71/S70/V70)
- Minor updates for other platforms, including davinci, s3c64xx,
prima2, stm32, broadcom nsp, amlogic, pxa, imx and renesas"
