Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC platform updates from Olof Johansson:
 "Here are the main updates for SoC support (besides DT additions) for
  ARM 32- and 64-bit platforms. The branch also contains defconfig
  updates to turn on drivers and options as needed on the various
  platforms.

  The largest parts of the delta are from cleanups moving platform data
  and board file setup of TI platforms to ti-sysc bus drivers. There are
  also some sweeping changes of eeprom and nand setup on Davinci, i.MX
  and other platforms.

  Samsung is removing support for Exynos5440, which was an oddball SoC
  that hasn't been seen much use in designs.

  Renesas is adding support for new SoCs (R-Car E3, RZ/G1C and RZ/N1D).

  Linus Walleij is also removing support for ux500 (Sony Ericsson)
  U8540/9540 SoCs that never made it to significant mass production and
  products"
