arm: dts: colibri-imx6: usb dual-role switching et. al.
This series is an assortment of USB dual-role specific commits as follows:
Introduce USBC_DET GPIO based USB dual-role aka device/host switching.
Move USB VBUS supply from single carrier board to module level device tree. This pin is as per Colibri module family standard.
Specify USBH_PEN GPIO being active-low rather than active-high (cosmetic only).
