Subject: [PATCH v3 1/7] ASoC: soc-component: Add snd_soc_pcm_component_ack
Date: Thu, 25 Feb 2021 10:52:37 +0800 [thread overview]
Message-ID: <1614221563-26822-2-git-send-email-shengjiu.wang@nxp.com> (raw)
In-Reply-To: <1614221563-26822-1-git-send-email-shengjiu.wang@nxp.com>
Add snd_soc_pcm_component_ack back, which can be used to get updated
buffer pointer in platform driver.
On Asymmetric multiprocessor, this pointer can be sent to Cortex-M
core for audio processing.
