Subject: [PATCH 0/6] Add MediaTek USB3 DRD Driver

These patches introduce the MediaTek USB3 dual-role controller
driver.

The driver can be configured as Dual-Role Device (DRD),
Peripheral Only and Host Only (xHCI) modes. It works well
with Mass Storage, RNDIS and g_zero on FS/HS and SS. And it is
tested on MT8173 platform which only contains USB2.0 device IP,
and on MT6290 platform which contains USB3.0 device IP.


Chunfeng Yun (6):
  dt-bindings: mt8173-xhci: support host side of dual-role mode
  usb: xhci-mtk: make IPPC register optional
  dt-bindings: mtu3: add devicetree bindings
  usb: Add MediaTek USB3 DRD Driver
  arm64: dts: mediatek: add USB3 DRD driver
  pinctrl: mt8173: set GPIO16 to usb iddig mode
