ASoC: max98396: add amplifier driver

2022-04-26T14:13:40Z

This series of patches adds support for Analog Devices MAX98396 mono amplifier with IV sense. The device provides a PCM interface for audio data and a standard I2C interface for control data communication. This driver also supports MAX98397 which is a variant of MAX98396 with wide input supply range.

ASoC: rt1016: enable building

2022-04-06T22:37:58Z

The rt1016 driver wasn't listed in Kconfig and Makefile, which AFAICT means it isn't ever built. This patch adds the appropriate entries to Kconfig and Makefile. Signed-off-by: Stephen Kitt Link: https://lore.kernel.org/r/20220405171158.2168762-1-steve@sk2.org Signed-off-by: Mark Brown

ASoC: cs35l45: Add driver for Cirrus Logic CS35L45 Smart Amp

2022-04-05T17:27:59Z

The CS35L45 is a 15 V Boosted Mono Class D Amplifier with DSP Speaker Protection and Adaptive Battery Management. This initial driver provides standard non-boosted audio operation without the DSP.

ASoC: wm8731: Factor out the I2C and SPI bus code into separate modules

2022-04-04T07:39:32Z

Placing both the I2C and SPI code in the same module causes problems with mixes of modular and non-modular builds of the buses so it's generally bad practice. As with other drivers split the bus code out of the WM8731 driver into separate modules.

ASoC: codecs: Add Awinic AW8738 audio amplifier driver

2022-03-07T13:13:01Z

The Awinic AW8738 is a simple audio amplifier using a single GPIO. The main difference to simple-amplifier is that there is a "one-wire pulse control" that allows configuring the amplifier to one of a few pre-defined modes. This can be used to configure the speaker-guard function (primarily the power limit for the amplifier). Add a simple driver that allows setting it up in the device tree with a specified mode number.

ASoC: codecs: Add power domains support in digital macro codecs

2022-02-28T13:30:37Z

Add support for enabling required power domains in digital macro codecs. macro and dcodec power domains are being requested as clocks by HLOS in ADSP based architectures and ADSP internally handling as powerdomains. In ADSP bypass case need to handle them as power domains explicitly.

ASoC: add support for TAS5805M digital amplifier

2022-01-24T13:31:24Z

The Texas Instruments TAS5805M is a class D audio amplifier with an integrated DSP. DSP configuration is supplied in a firmware image specified through a device-tree attribute. These register writes set up application-specific DSP settings and are expected to be generated using TI's PPC3 tool.

ASoC: cs35l41: Convert tables to shared source code

2021-12-31T13:21:00Z

To support CS35L41 in HDA systems the HDA driver for CS35L41 would have to duplicate some functions that already exist on ASoC driver So instead of duplicate the code, use the new lib source as a shared resource for both ASoC and HDA Also, change the way CONFIG_SND_SOC_CS35L41 is selected, as reported by Intel Kernel test robot, it is possible to build SND_SOC_CS35L41_SPI/I2C without the main driver, which would lead to build failures.

ASoC: Add AK4375 support

2021-12-21T18:05:45Z

AK4375 is a 32-bit stereo DAC with headphones amplifier. There's no documentation for it on akm.com, and only a brief datasheet can be found floating on the internets [1]. Thanks to Oriane BAYERD for finally answering my inquiries through akm.com, if only to tell me that this chip is EOL following AKM factory burning in october 2020 and thus no detailed documentation is available anymore... AK4331 is advertised [2] as pin and register compatible with AK4375 so some scraps of its datasheet were used and this driver might be used as a base for it, but this is totally untested. So this driver is mainly based on downstream code [3] and [4] by Hu Jin from AKM (no known email). Tested on msm8916-alcatel-idol347 and msm8939-alcatel-idol3, which both use PLL driven clock with bypass of SRC (sample rate converter), so only this setup is supported for now.
