Merge tag 'amlogic-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/khilman/linux-amlogic into next/dt

Amlogic 32-bit DT changes for v4.13:
- minor reorganization to support different busses
- add/use real clock controller

* tag 'amlogic-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/khilman/linux-amlogic:
  ARM: dts: meson8: add and use the real clock controller
  ARM: dts: meson: Extend L2 cache controller node for Meson8 and Meson8b
  ARM: dts: meson8b: inherit meson.dtsi from meson8b.dtsi
  ARM: dts: meson: organize devices in their corresponding busses
