Subject: [PATCH v6 14/24] ASoC: qdsp6: q6asm: Add q6asm driver
Date: Thu, 26 Apr 2018 10:45:56 +0100	[thread overview]
Message-ID: <20180426094606.4775-15-srinivas.kandagatla@linaro.org> (raw)
In-Reply-To: <20180426094606.4775-1-srinivas.kandagatla@linaro.org>

From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>

This patch adds basic support to Q6 ASM (Audio Stream Manager) module on
Q6DSP. ASM supports up to 8 concurrent streams. each stream can be setup
as playback/capture. ASM provides top control functions like
Pause/flush/resume for playback and record. ASM can Create/destroy encoder,
decoder and also provides POPP dynamic services.

This patch adds support to basic features to allow hdmi playback.

Subject: [PATCH v6 14/24] ASoC: qdsp6: q6asm: Add q6asm driver
Date: Thu, 26 Apr 2018 10:45:56 +0100	[thread overview]
Message-ID: <20180426094606.4775-15-srinivas.kandagatla@linaro.org> (raw)
In-Reply-To: <20180426094606.4775-1-srinivas.kandagatla@linaro.org>

From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>

This patch adds basic support to Q6 ASM (Audio Stream Manager) module on
Q6DSP. ASM supports up to 8 concurrent streams. each stream can be setup
as playback/capture. ASM provides top control functions like
Pause/flush/resume for playback and record. ASM can Create/destroy encoder,
decoder and also provides POPP dynamic services.

This patch adds support to basic features to allow hdmi playback.
