ASoC: tegra: Add Tegra210 based OPE driver

2022-06-06T11:33:07Z

The Output Processing Engine (OPE) is one of the AHUB client. It has PEQ (Parametric Equalizer) and MBDRC (Multi Band Dynamic Range Compressor) sub blocks for data processing. The PEQ block gets samples from the MBDRC block. This patch registers OPE driver with ASoC framework. The component driver exposes DAPM widgets, routes and kcontrols for the device. The DAI driver exposes OPE interfaces, which can be used to connect different components in the ASoC layer. Makefile and Kconfig support is added to allow build the driver.

ASoC: tegra: Add Tegra186 based ASRC driver

2022-04-04T07:39:14Z

Asynchronous Sample Rate Converter (ASRC) converts the sampling frequency of the input signal from one frequency to another. It can handle over a wide range of sample rate ratios (freq_in/freq_out) from 1:24 to 24:1. ASRC has two modes of operation. One where ratio can be programmed in SW and the other where it gets the information from ratio estimator module. The latter mode above can help address the cases where the sample rate is not known at the stream set up time or is potentially time varying. In addition, the ratio between input and output sample rate can be any arbitrary number and the input and output clocks could be derived from asynchronous clocks. This patch registers ASRC driver with ASoC framework. The component driver exposes DAPM widgets, routes and kcontrols for the device. The DAI driver exposes ASRC interfaces, which can be used to connect different components in the ASoC layer. Makefile and Kconfig support is added to allow build the driver.

ASoC: tegra: Add Tegra210 based Mixer driver

2021-09-20T12:31:36Z

The Mixer supports mixing of up to ten 7.1 audio input streams and generate five outputs (each of which can be any combination of the ten input streams) This patch registers Mixer driver with ASoC framework. The component driver exposes DAPM widgets, routes and kcontrols for the device. The DAI driver exposes Mixer interfaces, which can be used to connect different components in the ASoC layer. Makefile and Kconfig support is added to allow build the driver. It can be enabled in the DT via "nvidia,tegra210-amixer" compatible binding.

ASoC: tegra: Add Tegra210 based ADX driver

2021-09-20T12:31:35Z

The Audio Demultiplexer (ADX) block takes an input stream with up to 16 channels and demultiplexes it into four output streams of up to 16 channels each. A byte RAM helps to form output frames by any combination of bytes from the input frame. Its design is identical to that of byte RAM in the AMX except that the data flow direction is reversed. This patch registers ADX driver with ASoC framework. The component driver exposes DAPM widgets, routes and kcontrols for the device. The DAI driver exposes ADX interfaces, which can be used to connect different components in the ASoC layer. Makefile and Kconfig support is added to allow build the driver. It can be enabled in the DT via "nvidia,tegra210-adx" compatible binding.

ASoC: tegra: Add Tegra210 based AMX driver

2021-09-20T12:31:34Z

The Audio Multiplexer (AMX) block can multiplex up to four input streams each of which can have maximum 16 channels and generate an output stream with maximum 16 channels. A byte RAM helps to form an output frame by any combination of bytes from the input frames. This patch registers AMX driver with ASoC framework. The component driver exposes DAPM widgets, routes and kcontrols for the device. The DAI driver exposes AMX interfaces, which can be used to connect different components in the ASoC layer. Makefile and Kconfig support is added to allow build the driver. It can be enabled in the DT via "nvidia,tegra210-amx" for Tegra210 and Tegra186. For Tegra194 and later, "nvidia,tegra194-amx" can be used. Signed-off-by: Sameer Pujar Link: https://lore.kernel.org/r/1631551342-25469-9-git-send-email-spujar@nvidia.com Signed-off-by: Mark Brown

ASoC: tegra: Add Tegra210 based SFC driver

2021-09-20T12:31:33Z

The Sampling Frequency Converter (SFC) converts the sampling frequency of the input signal from one frequency to another. It supports sampling frequency conversions of streams of up to two channels (stereo). This patch registers SFC driver with ASoC framework.

ASoC: tegra: Add Tegra210 based MVC driver

2021-09-20T12:31:32Z

The Master Volume Control (MVC) provides gain or attenuation to a digital signal path. It can be used in input or output signal path for per-stream volume control or it can be used as master volume control. The MVC block has one input and one output. The input digital stream can be mono or multi-channel (up to 7.1 channels) stream. An independent mute control is also included in the MVC block. This patch registers MVC driver with ASoC framework. The component driver exposes DAPM widgets, routes and kcontrols for the device. The DAI driver exposes MVC interfaces, which can be used to connect different components in the ASoC layer. Makefile and Kconfig support is added to allow build the driver. It can be enabled in the DT via "nvidia,tegra210-mvc" compatible binding.

ASoC: tegra: Add audio graph based card driver

2021-01-19T14:09:21Z

Add Tegra audio machine driver which is based on generic audio graph card driver. It re-uses most of the common stuff from audio graph driver and uses the same DT binding. Required Tegra specific customizations are done in the driver and additional DT bindings are required for clock handling. Details on the customizations done: - Update PLL rates at runtime: Tegra HW supports multiple sample rates (multiples of 8x and 11.025x) and both of these groups require different PLL rates. Hence there is a requirement to update this at runtime. This is achieved by providing a custom 'snd_soc_ops' and in hw_param() callback PLL rate is updated as per the sample rate. - Internal structure 'tegra_audio_graph_data' is used to maintain clock handles of PLL. - The 'force_dpcm' flag is set to use DPCM for all DAI links. - The 'component_chaining' flag is set to use DPCM with component model.
