#1700737 — [PATCH 0/3] add some quirks for Rockchip usb2-phy and add rv1108 SoCs' support

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

Frank Wang (3):
  phy: rockchip-inno-usb2: add companion grf quirk
  phy: rockchip-inno-usb2: add otg mux irq quirk
  phy: rockchip-inno-usb2: add support of usb2-phy for rv1108 SoCs

#1700739 — [PATCH 2/3] phy: rockchip-inno-usb2: add otg mux irq quirk

The otg-id/otg-bvalid/linestate irqs are multiplexed to one irq in
otg-port on some Rockchip SoC (e.g RV1108), this patch add a quirk
to support this mux irq feature.
