This patch exports an inline function tegra_set_cif() which can be used, for now, to program CIF on Tegra210 and later Tegra generations. Later it can be extended to include helpers for legacy chips as well.

The DMIC controller implements a converter to convert PDM signals to Pulse Code Modulation (PCM) signals. From signal flow perspective, the DMIC can be viewed as a PDM receiver. This patch registers DMIC component with ASoC framework. The component driver exposes DAPM widgets, routes and kcontrols for the device. The DAI driver exposes DMIC interfaces, which can be used to connect different components in the ASoC layer. Makefile and Kconfig support is added to allow to build the driver. The DMIC devices can be enabled in the DT via "nvidia,tegra210-dmic" compatible string. This driver can be used for Tegra186 and Tegra194 chips as well.

It can interface with I2S compatible devices. Tegra I2S controller can operate as both master and slave. This patch registers I2S controller with ASoC framework. The component driver exposes DAPM widgets, routes and kcontrols for the device. The DAI driver exposes I2S interfaces, which can be used to connect different components in the ASoC layer. Makefile and Kconfig support is added to allow to build the driver. The I2S devices can be enabled in the DT via "nvidia,tegra210-i2s" compatible binding.

AHUB supports multiple interfaces to I2S, DSPK, DMIC etc., XBAR is a switch used to configure or modify audio routing between HW accelerators present inside AHUB. This patch registers AHUB component with ASoC framework. The component driver exposes DAPM widgets, routes and kcontrols for the device. The DAI driver exposes AHUB interfaces, which can be used to connect different components in the ASoC layer. Currently the driver takes care of XBAR programming to allow audio data flow through various clients of the AHUB. Makefile and Kconfig support is added to allow to build the driver. The AHUB component can be enabled in the DT via below compatible bindings. - "nvidia,tegra210-ahub" for Tegra210 - "nvidia,tegra186-ahub" for Tegra186 and Tegra194 Signed-off-by: Sameer Pujar --- sound/soc/tegra/Kconfig | 10 + sound/soc/tegra/Makefile | 2 + sound/soc/tegra/tegra210_ahub.c | 578 ++++++++++++++++++++++++++++++++++++++++ sound/soc/tegra/tegra210_ahub.h | 100 +++++++ 4 files changed, 690 insertions(+) create mode 100644 sound/soc/tegra/tegra210_ahub.c create mode 100644 sound/soc/tegra/tegra210_ahub.h diff --git a/sound/soc/tegra/Kconfig b/sound/soc/tegra/Kconfig index 157fa7a..3166d03 100644 --- a/sound/soc/tegra/Kconfig +++ b/sound/soc/tegra/Kconfig @@ -62,6 +62,16 @@ config SND_SOC_TEGRA30_I2S Tegra30 I2S interface.

From the signal flow perpsective, the DSPK can be viewed as a PDM transmitter that up-samples the input to the desired sampling rate by interpolation then converts the oversampled PCM input to the desired 1-bit output via Delta Sigma Modulation (DSM). This patch registers DSPK component with ASoC framework. The component driver exposes DAPM widgets, routes and kcontrols for the device. The DAI driver exposes DSPK interfaces, which can be used to connect different components in the ASoC layer. Makefile and Kconfig support is added to allow to build the driver. The DSPK devices can be enabled in the DT via "nvidia,tegra186-dspk" compatible binding. This driver can be used on Tegra194 chip as well.

Each ADMA channel that sends/receives data to/from AHUB must intreface through an ADMAIF channel. ADMA channel sending data to AHUB pairs with an ADMAIF Tx channel and similarly ADMA channel receiving data from AHUB pairs with an ADMAIF Rx channel. Buffer size is configurable for each ADMAIF channel, but currently SW uses default values. This patch registers ADMAIF driver with ASoC framework. The component driver exposes DAPM widgets, routes and kcontrols for the device. The DAI driver exposes ADMAIF interfaces, which can be used to connect different components in the ASoC layer. Makefile and Kconfig support is added to allow to build the driver. The ADMAIF device can be enabled in the DT via "nvidia,tegra210-admaif" compatible binding. Tegra PCM driver is updated to expose required PCM interfaces and snd_pcm_ops callbacks.

Currently "sound-name-prefix" defined in a component is not taking effect. Actually the property is not getting parsed. It can be fixed by parsing "sound-name-prefix" property whenever "prefix" is missing in DAI link Codec node.

bitclock-master=<&cpu1>; frame-master=<&cpu1>; cpu1: cpu@0 { ... }; codec@0 { ... }; ... }; In above case CPU is expected to be configured as a master and Codec as a slave device. But both CPU/Codec are being configured as slave devices. This happens because asoc_simple_parse_daifmt() uses Codec reference and sets up the 'dai_link->dai_fmt' accordingly while parsing both CPU and Codec. Though populating 'non_legacy_dai_naming' flag as true for CPU component can address above issue in simple cases, but with multiple CPU/Codecs with DPCM DAI link it becomes tricky because right now the first Codec in the DAI link is used as reference. This is fixed by passing current DAI link child node reference to asoc_simple_parse_daifmt(). It parses a CPU/Codec node independently and sets daifmt as per 'bitcloclk/frame-master' property.

Though mostly CPU won't use/require 'mclk-fs' property, looping over 'np' (current child node in a DAI link) can help in cases where multiple Codecs are defined. This further helps to get rid of 'codec' argument from simple_dai_link_of_dpcm() function, which gets called for DPCM links.

In some cases it is required to have multiple CPU/Codecs. Currently parsing logic for DPCM link loops over all children of DAI link but assumes that there is a single Codec entry. When DAI link has multiple Codecs it considers only the first Codec entry and remaining Codecs are wrongly treated as CPU. This happens because first Codec is used as reference for parsing all other child nodes. This is fixed by using string comparisons of child node names instead of node pointer reference in simple_dai_link_of_dpcm(). So All CPU get parsed in first run and all Codecs in subsequent run. After this simple_dai_link_of_dpcm() does not required 'codec' argument and hence is removed.

For example it fails for Microphone which can support CAPTURE stream only. This happens because simple-card driver by default populates both stream directions. This can be fixed by populating directions based on DAI capability. For 'CPU<->Dummy' DAI links CPU is used to setup the direction and similarly Codec is used for 'Dummy<->Codec' DAI links.

DPCM dai links use CPU<->Dummy or Dummy<->Codec style of links in simple-card driver and hence do not have required DAI connections by default. Usually machine driver can do the necessary mapping. But if there is a crossbar switch HW which can connect multiple components, it is expected to provide required user space configurability via MUX controls. In such a case the crossbar can be represented as an independent component and can be added as an auxiliary device. The exposed routing interfaces can be used by other components in the system, thus probing it first can avoid probe failures.

Such DAI links have CPU component which implement pcm_construct() and pcm_destruct() callbacks. Based on this, current patch exposes a helper function to identify such components and populate 'no_pcm' flag for DPCM DAI link. This helps to have BE<->BE component links where PCM devices need not be created for CPU components involved in the links.

The sound cards requiring DPCM DAI link support use DPCM_SELECTABLE flag and DAI links are treated as DPCM links depending on the number of child nodes in a given DAI link. There is another requirement where multiple ASoC components need to be connected together in a chained fashion in a component model. This patch sets 'component_chaining' flag for such sound cards where FE<->BE and multiple BE<->BE component connections is required. Hence support for such sound cards is added under 'simple-cc-audio-card' compatible. All DAI links under this are treated as DPCM links and links can have empty Codec list since components are chainied via router controls.

Along with this specific instances of I/O modules are enabled as per the board design. * Jetson TX1 - I2S1, I2S2, I2S3, I2S4 and I2S5 - DMIC1, DMIC2 and DMIC3 * Jetson Nano - I2S3 and I2S4 - DMIC1 and DMIC2 * Jetson TX2 - I2S1, I2S2, I2S3, I2S4, I2S5 and I2S6 - DMIC1, DMIC2 and DMIC3 - DSPK2 * Jetson AGX Xavier - I2S1, I2S2, I2S4 and I2S6 - DMIC2 and DMIC3 - DSPK1 This helps to register above components with ASoC core.

Earlier in the series simple-card driver is enhanced to work with multiple ASoC components. Based on board design required I/O interfaces are exposed for I2S and DMIC. More complicated audio paths will be added going forward.
