[PATCH 0/3] arm64: dts: rockchip: add io-domain support for rk3368 and rk3399

[Heiko Stuebner]

This adds the core io-domain nodes for both the rk3368 and rk3399
as well as the actual supplies on the rk3368-r88 board.

This of course needs
    PM / AVS: rockchip-io: make io-domains a child of the GRF
that went into mainline during the 4.7 merge window.
