Subject: [PATCH v3 08/13] ASoC: audio-graph: Expose helpers from audio graph
Date: Thu, 1 Oct 2020 23:03:02 +0530 [thread overview]
Message-ID: <1601573587-15288-9-git-send-email-spujar@nvidia.com> (raw)
In-Reply-To: <1601573587-15288-1-git-send-email-spujar@nvidia.com>
This commit exposes following functions which can be used by a sound
card driver based on audio graph driver. Idea is vendors can have a
thin driver and re-use common stuff from audio graph driver.
- graph_card_probe()
- graph_get_dais_count()
- graph_parse_of()
In doing so a new header file is added for audio graph which can be
included by vendor drivers.
