The general register files are present on all Rockchip SoCs I've seen so far 
and really are just an aggregation of registers for settings and status 
indications, ranging from memory stuff, dma-controller settings, usb-phy and 
settings for a lot of other phys, etc.

The most prevalent description in dt-bindings is currently:

- rockchip,grf: phandle to the syscon managing the "general register files"
