Merge tag 'armsoc-dt64' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull 64-bit ARM DT updates from Olof Johansson:
 "Just as the 32-bit contents, the 64-bit device tree branch also
  contains a number of additions this release cycle.

  New platforms:
   - LG LG1313
   - Mediatek MT6755
   - Renesas r8a7796
   - Broadcom 2837

  Other platforms with larger updates are:
   - Nvidia X1 platforms (USB 3.0, regulators, display subsystem)
   - Mediatek MT8173 (display subsystem added)
   - Rockchip RK3399 (a lot of new peripherals)
   - ARM Juno reference implementation (SCPI power domains, coresight,
     thermal)"
