Subject: [PATCH 06/10] ASoC: soc-pcm: Get all BEs along DAPM path
Date: Sun, 19 Jul 2020 10:40:13 +0530 [thread overview]
Message-ID: <1595135417-16589-7-git-send-email-spujar@nvidia.com> (raw)
In-Reply-To: <1595135417-16589-1-git-send-email-spujar-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>
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.
