Not sure if I missed something, CHECK_DTBS report below warning.

arch/arm64/boot/dts/freescale/imx8qxp-colibri-iris.dtb: usbc-det: 'id-gpio' does not match any of the regexes: 'pinctrl-[0-9]+'
	from schema $id: http://devicetree.org/schemas/extcon/linux,extcon-usb-gpio.yaml

Needn't regulator-always-on, because reg_usbh_vbus referece by other node.

This should be `id-gpios`. The binding for "linux,extcon-usb-gpio" was recently
added, and this was not tested on the latest next (my fault), but on shawn imx branch and
the old txt doc documented just `id-gpio`.

We'll fix it. And thanks for catching it.

Is this an issue? we expect this regulator to be always on, therefore this is
described this way in the DT.

No a issue. If some device refer this regulator, suppose it only need power
on when this device probe. No sure why need always on.
