Subject: ucm2: MediaTek: mt8391-evk: Add DisplayPort output audio support
X-Git-Url: https://git.alsa-project.org/?a=commitdiff_plain;h=8048d93df19180972cb558b88cf1115ac091afc9;p=alsa-ucm-conf.git

ucm2: MediaTek: mt8391-evk: Add DisplayPort output audio support

Add an HDMI device for DisplayPort output on hw:CardId,5, guarded by a
ControlExists condition on the 'DP Jack' control so it only shows up
when the DPTX back end is enabled in the device tree.

Closes: https://github.com/alsa-project/alsa-ucm-conf/pull/797
