[PATCH v3 0/5] add some quirks for Rockchip usb2-phy and add rv1108 SoCs' support

[Frank Wang]

These series of patches add companion_grf_quirk and otg_mux interrupt for
rockchip usb2-phy. In addition, this change also add rv1108 usb2-phy support.

Changes from v2:
 - Amend otg-mux interrupt to be auto-detectable and update related dt-bindings.

Changes from v1:
 - Send the dt-bindings as a separate patch and cc devicetree list.

[PATCH v3 1/5] phy: rockchip-inno-usb2: add companion grf quirk

[Frank Wang]

The registers of usb-phy are distributed in grf and usbgrf on some
Rockchip SoCs (e.g RV1108), this patch add a quirk to support this
companion grf design.

[PATCH v3 2/5] dt-bindings: phy-rockchip-inno-usb2: add companion grf quirk

[Frank Wang]

Add rockchip,usbgrf and rockchip,companion_grf_quirk to support
the registers of usb-phy that are distributed in grf and usbgrf
on some special Rockchip SoCs (e.g RV1108).

specific compatible string enough? 

In any case, use '-' rather than '_'.
