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.

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