From: Chris Morgan <macromorgan@xxxxxxxxxxx>
Devices integrating Allwinner SoCs may use line-out or headphone jacks
with jack detection circuits attached to a GPIO. For example, a number
of Anbernic devices featuring the H700 SoC use this mechanism to switch
between a headphone jack and an internal speaker.
Add extra routing endpoints to support this.
