ASoC: soc-card: Create jack kcontrol without pins

2022-04-14T16:37:21Z

snd_soc_card_jack_new() allowed to create jack kcontrol without pins, but did not create kcontrols. The jack would not have kcontrols if pins were not going to be added. This renames the old snd_soc_card_jack_new() to snd_soc_card_jack_new_pins() for use when pins are provided or will be added later. The new snd_soc_card_jack_new() appropriately creates a jack for use without pins and adds a kcontrol.

ASoC: tegra: AHUB routes for ASRC module

2022-04-04T07:39:15Z

Add AHUB routes for ASRC module. The ASRC module can be plugged into audio path as per the need. The routing controls can be used to setup the audio path with ASRC similar to the already existing routes. The routes are added to Tegra186 and later Tegra SoCs where ASRC module is present.

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: tegra20: spdif: make const array rates static

2022-02-15T12:52:44Z

Don't populate the read-only const array rates on the stack but instead it static. Also makes the object code a little smaller. Signed-off-by: Colin Ian King Link: https://lore.kernel.org/r/20220214213223.65780-1-colin.i.king@gmail.com Signed-off-by: Mark Brown

ASoC: tegra20: i2s: Filter out unsupported rates

2021-12-17T11:14:01Z

Support new nvidia,fixed-parent-rate device-tree property which instructs I2S that board wants parent clock rate to stay at a fixed rate. This allows to play audio over S/PDIF and I2S simultaneously. The root of the problem is that audio components on Tegra share the same audio PLL, and thus, only a subset of rates can be supported if we want to play audio simultaneously. Filter out audio rates that don't match parent clock rate if device-tree has the nvidia,fixed-parent-rate property.

ASoC: tegra20: spdif: Filter out unsupported rates

2021-12-17T11:13:59Z

SPDIF and other SoC components share audio PLL on Tegra, thus only one component may set the desired base clock rate. This creates problem for HDMI audio because it uses SPDIF and audio may not work if SPDIF's clock doesn't exactly match standard audio rate since some receivers may reject audio in that case. Filter out audio rates which SPDIF output can't support, assuming that other components won't change rate at runtime.

Support system suspend by enforcing runtime PM suspend/resume. Now there is no doubt that h/w is indeed stopped during suspend and that h/w state will be properly restored after resume.
