Merge tag 'v3.19-meson-dts' of https://github.com/carlocaione/linux-meson into next/dt

Pull "ARM: meson: DTS related changes" from Carlo Caione:

here is the pull request for the DT related changes for the 3.19.
It's mainly the work done by Beniamino for the preliminary support of
the Amlogic Meson8 SoC, the support for L2 cache and the I2C
controller.
Please note that the support for the Tronsmart S89 Elite TV box has not
been included since the Meson8 development will be done now on a
different dev board kindly provided by Amlogic.

* tag 'v3.19-meson-dts' of https://github.com/carlocaione/linux-meson:
  ARM: dts: meson: add I2C controller nodes
  ARM: meson: DTS: enable L2 cache
  ARM: dts: add dtsi for Amlogic Meson8 SoCs
  DTS: meson: Add forgotten compatible in board DTS
