From 7bda89a2489fb012c4c63f3338827ad1f35c8880 Mon Sep 17 00:00:00 2001 From: Chris Morgan Date: Sat, 15 Feb 2025 11:02:23 +1300 Subject: [PATCH] ASoC: dt-bindings: sun4i-a10-codec: add hp-det-gpios Devices integrating Allwinner SoCs may use line-out or headphone jacks with jack detection circuits attached to a GPIO. Support defining these in DTs. A number of Anbernic devices featuring the H700 SoC use this mechanism to switch between a headphone jack and an internal speaker, so add these to the allowed routing items.
