ASoC: tegra: remove Kconfig dependency on TEGRA20_APB_DMA

2025-11-26T13:03:05Z

The ALSA SoC driver for Tegra runs also on SoCs without the Tegra20 APB DMA controller (e.g. Tegra234). Signed-off-by: Francesco Lavra Link: https://patch.msgid.link/20251126112926.4126757-1-flavra@baylibre.com Signed-off-by: Mark Brown

ASoC: tegra: Standardize ASoC menu

2025-06-24T00:01:28Z

Current Kconfig menu at [ALSA for SoC audio support] has no rules. So, some venders are using menu style, some venders are listed each drivers on top page, etc. It is difficult to find target vender and/or drivers because it is very random. Let's standardize ASoC menu Signed-off-by: Kuninori Morimoto Reviewed-by: Jon Hunter Link: https://patch.msgid.link/878qlxzqd0.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown

ASoC: tegra: select CONFIG_SND_SIMPLE_CARD_UTILS

2024-07-22T12:04:50Z

This I2S client driver now uses functions exported from a helper module but fails to link when the helper is disabled: ERROR: modpost: "simple_util_parse_convert" [sound/soc/tegra/snd-soc-tegra210-i2s.ko] undefined!

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.
