[PATCH 0/2] add support for gpio-usb-b-connector

[Tim Harvey]

Linux has a driver for gpio-usb-b-connector that uses a GPIO to
determine host vs peripheral role. This can be useful for USB Type-B
OTG connectors which have an ID pin that is grounded on OTG-to-host
cables and floating on OTG-to-device cables as well as USB power switch
controllers such as the TPS25821 which manages cc pins and has a SINK#
output.

Both scenarios are used for various imx8mp-venice boards.

This series addes support for usb controllers in otg mode
(dr_mode="otg") which have a remote endpoint connector with compatible
'gpio-usb-b-connector' with an id-gpios property.

The first patch adds this capability to the usb_get_dr_mode() function
and the second disables the workarounds used for various imx8mp-venice
boards to default the usb dual-role controllers to host mode.

  usb: common: allow dr_mode to come from gpio-id based usb-connector
  imx8mp-venice: enable USB device mode
