Merge tag 'armsoc-arm64' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC 64-bit changes from Olof Johansson:
 "Here's our branch of ARM64 contents for this merge window.

  Most of this is DT contents for new SoCs (or those who have seen new
  device support added).  Maybe we should stop separating out the arm64
  contents here to avoid the kind of internal conflicts as we got this
  time around, where 32- and 64-bit contents conflicted.

  Anyhow, on the actual contents:

  New SoCs:

   - Broadcom North Star 2 (ns2)
   - Marvell Berlin4CT
   - Mediatek MT6795
   - Rockchip RK3368

  In addition, there are enhancements for the following platforms:

   - Mediatek MT8173: cpuidle-dt updates, misc other additions
   - ZyncMP: A bunch of devices added to the existing DTSI
   - Qualcomm MSM8916 and APQ8016 updates for USB, etc.

  + a handful of other updates for various platforms"
