Merge tag 'v4.1-rockchip-dts1' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip into next/dt

Merge "ARM: rockchip: dts changes for 4.1" from Heiko Stuebner:

This adds and enables the usbphy nodes on the rk3288 boards and enables
the gmac on the firefly board. A new board the Popmetal-rk3288 is also
added. And finally the pmic supplies for act8846 based boards are added,
as the act8865/act8846 driver gained supply handling in the regulator tree.

* tag 'v4.1-rockchip-dts1' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip:
  ARM: dts: rockchip: complete rk3288-evb pmic supplies
  ARM: dts: rockchip: add input supplies for the act8846 on Radxa Rock
  ARM: dts: add rk3288 PopMetal board
  dt-bindings: add root compatible property for PopMetal board
  ARM: dts: rockchip: enable gmac on rk3288-firefly
  ARM: dts: rockchip: enable usbphy on rk3288-firefly
  ARM: dts: rockchip: Enable usb PHY on rk3288-evb board
  ARM: dts: rockchip: add rk3288 usb PHY
