Subject: sun4i-codec: add routing for headphones and internal speaker
X-Git-Tag: v1.2.14~63
X-Git-Url: https://git.alsa-project.org/?a=commitdiff_plain;h=24008a2f93b39a33863c7e64ab2f7214d9970a1c;p=alsa-ucm-conf.git

sun4i-codec: add routing for headphones and internal speaker

The sun4i-codec kernel driver covers a large number of Allwinner SoCs.
The H616 codec has a single line-out route, which is used in concert
with a Toshiba mux chip to send audio to either an internal speaker or
headphone jack on a number of Anbernic handheld gaming devices.

Add a UCM configuration to allow enabling/disabling the speaker amp
depending on whether headphones are in use or not.
