Subject: [PATCH v2 4/9] ASoC: soc-pcm: Get all BEs along DAPM path
Date: Wed, 5 Aug 2020 10:54:19 +0530 [thread overview]
Message-ID: <1596605064-27748-5-git-send-email-spujar@nvidia.com> (raw)
In-Reply-To: <1596605064-27748-1-git-send-email-spujar@nvidia.com>
dpcm_end_walk_at_be() stops the graph walk when first BE is found for
the given FE component. In a component model we may want to connect
multiple DAIs from different components. A new flag is introduced in
'snd_soc_card', which when set allows DAI/component chaining. Later
PCM operations can be called for all these listed components for a
valid DAPM path.
