[PATCH v2 1/5] ASoC: dt-bindings: sun4i-a10-codec: add hp-det-gpios

[Ryan Walklin <ryan@xxxxxxxxxxxxx>]

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.
