ASoC: zl38060 add gpiolib dependency

2023-02-28T13:59:56+00:00

Without gpiolib, this driver fails to link: arm-linux-gnueabi-ld: sound/soc/codecs/zl38060.o: in function `chip_gpio_get': zl38060.c:(.text+0x30): undefined reference to `gpiochip_get_data' arm-linux-gnueabi-ld: sound/soc/codecs/zl38060.o: in function `zl38_spi_probe': zl38060.c:(.text+0xa18): undefined reference to `devm_gpiochip_add_data_with_key' This appears to have been in the driver since the start, but is hard to hit in randconfig testing since gpiolib is almost always selected by something else.

ASoC: cs35l45: Remove separate tables module

2023-02-15T13:10:44+00:00

There is no reason to have a separate module for the tables file it just holds regmap callbacks and register patches used by the main part of the driver. Remove the separate module and merge it into the main driver module.

ASoC: cs42l42: Add SoundWire support

2023-01-31T17:07:56+00:00

Merge series from Stefan Binding : The CS42L42 has a SoundWire interface for control and audio. This chain of patches adds support for this. Patches #1 .. #5 split out various changes to the existing code that are needed for adding Soundwire. These are mostly around clocking and supporting the separate probe and enumeration stages in SoundWire. Patches #6 .. #8 actually adds the SoundWire handling.

Merge series from wangweidong.a@awinic.com: The Awinic AW88395 is an I2S/TDM input, high efficiency digital Smart K audio amplifier with an integrated 10.25V smart boost converter. Add a DT schema for describing Awinic AW88395 audio amplifiers. They are controlled using I2C

ASoC: cs42l42: Add SoundWire support

2023-01-31T12:10:50+00:00

This adds support for using CS42L42 as a SoundWire device. SoundWire-specifics are kept separate from the I2S implementation as much as possible, aiming to limit the risk of breaking the I2C+I2S support. There are some important differences in the silicon behaviour between I2S and SoundWire mode that are reflected in the implementation: - ASP (I2S) most not be used in SoundWire mode because the two interfaces share pins. - The SoundWire capture (record) port only supports 1 channel. It does not have left-to-right duplication like the ASP. - DP2 can only be prepared if the HP has powered-up. DP1 can only be prepared if the ADC has powered-up. (This ordering restriction does not exist for ASPs.) The SoundWire core port-prepare step is triggered by the DAI-link prepare(). This happens before the codec DAI prepare() or the DAPM sequence so these cannot be used to enable HP/ADC. Instead the HP/ADC enable/disable are done during the port_prep callback. - The SRCs are an integral part of the audio chain but in silicon their power control is linked to the ASP. There is no equivalent power link to SoundWire DPs so the driver must take "manual" control of SRC power. - The SoundWire control registers occupy the lower part of the SoundWire address space so cs42l42 registers are offset by 0x8000 (non-paged) in SoundWire mode. - Register addresses are 8-bit paged in I2C mode but 16-bit unpaged in SoundWire. - Special procedures are needed on register read/writes to (a) ensure that the previous internal bus transaction has completed, and (b) handle delayed read results, when the read value could not be returned within the SoundWire read command. There are also some differences in driver implementation between I2S and SoundWire operation: - CS42L42 I2S does not runtime_suspend, but runtime_suspend/resume support has been added into the driver in SoundWire mode as the most convenient way to power-up the bus manager and to handle the unattach_request condition, though the CS42L42 chip does not itself suspend or resume. - Intel SoundWire host controllers have a low-power clock-stop mode that requires resetting all peripherals when resuming. This means that the interrupt registers will be reset in between the interrupt being generated and the interrupt being handled, and since the interrupt status is debounced, these values may not be accurate immediately, and may cause spurious unplug events before settling. - As in I2S mode, the PLL is only used while audio is active because of clocking quirks in the silicon. For SoundWire the cs42l42_pll_config() is deferred until the DAI prepare(), to allow the cs42l42_bus_config() callback to set the SCLK.
