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" Heiko -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
