Subject: [PATCH v1 1/2] ASoC: dt-bindings: meson: introduce link-name optional property
Date: Mon, 8 Apr 2024 19:49:39 +0300 [thread overview]
Message-ID: <20240408164947.30717-2-ddrokosov@salutedevices.com> (raw)
In-Reply-To: <20240408164947.30717-1-ddrokosov@salutedevices.com>
The 'link-name' property is an optional DT property that allows for the
customization of the name associated with the DAI link and PCM stream.
This functionality mirrors the approach commonly utilized in Qualcomm
audio cards, providing flexibility in DAI naming conventions for
improved system integration and userspace experience.
It allows userspace program to easy determine PCM stream purpose, e.g.:
~ # cat /proc/asound/pcm
00-00: speaker (*) : : playback 1
00-01: mics (*) : : capture 1
00-02: loopback (*) : : capture 1
