[PATCH v4 0/5] Update Lpass digital codec macro drivers
by Srinivasa Rao Mandadapu 26 Oct '21

26 Oct '21

This patch set is to add support for lpass sc7280 based targets. Upadate compatible name and change of bulk clock voting to optional clock voting in digital codecs va, rx, tx macro drivers. Changes Since V3: -- Removed fixes tag. -- Change signedoff by sequence. Changes Since V2: -- Add Tx macro deafults for lpass sc7280 Changes Since V1: -- Removed individual clock voting and used bulk clock optional. -- Removed volatile changes and fixed default values. -- Typo errors.

[RESEND PATCH v10 00/17] ASoC: qcom: Add AudioReach support

Hi Mark, Am resending this series as I ended up sending incorrect patches for v10. Sorry for the resend noise. This version is a respin of v9 fixing a build error in 12/17 patch. QCOM SoC relevant non-audio patches in this series has been merged into the Qualcomm drivers-for-5.16 tree, as this series depends those patches an immutable tag is available at: https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux.git tags/20210927135559.738-6-srinivas.kandagatla(a)linaro.org This patchset adds ASoC driver support to configure signal processing framework ("AudioReach") which is integral part of Qualcomm next generation audio SDK and will be deployed on upcoming Qualcomm chipsets. It makes use of ASoC Topology to load graphs on to the DSP which is then managed by APM (Audio Processing Manager) service to prepare/start/stop. Here is simplified high-level block diagram of AudioReach: ___________________________________________________________ | CPU (Application Processor) | | +---------+ +---------+ +----------+ | | | q6apm | | q6apm | | q6apm | | | | dais | <------> | | <-----> |lpass-dais| | | +---------+ +---------+ +----------+ | | ^ ^ | | | | +---------+ | | +---------+ v +---------->|topology | | | | q6prm | +---------+ | | | | | |<-------->| GPR | +---------+ | | +---------+ +---------+ | | ^ ^ | | | | | | +----------+ | | | | q6prm | | | | |lpass-clks| | | | +----------+ | | |____________________________|______________________________| | | RPMSG (IPC over GLINK) ____________________________|______________________________ | | | | +-----------------------+ | | | | | | v v q6 (Audio DSP) | |+-----+ +----------------------------------+ | || PRM | | APM (Audio Processing Manager) | | |+-----+ | .

There are also control/event paths between modules that can be wired up while building graph to achieve various control mechanism between modules. These concepts of Sub-Graph, Containers and Modules are represented in ASoC topology.
