2019-11-18ASoC: tlv320aic31xx: configure output common-mode voltageLucas Stach
The tlv320aic31xx devices allow to adjust the output common-mode voltage for best analog performance. The datasheet states that the common mode voltage should be set to be <= AVDD/2. This changes allows to configure the output common-mode voltage via a DT property. If the property is absent the voltage is automatically chosen as the highest voltage below/equal to AVDD/2.

2019-11-15ASoC: wm8904: fix regcache handlingMichael Walle
The current code assumes that the power is turned off in SND_SOC_BIAS_OFF. If there are no actual regulator the codec isn't turned off and the registers are not reset to their default values but the regcache is still marked as dirty. Thus a value might not be written to the hardware if it is set to the default value. Do a software reset before turning off the power to make sure the registers are always reset to their default states.

2019-11-11ASoC: rt5645: Fixed buddy jack support.Jacob Rasmussen
The headphone jack on buddy was broken with the following commit: commit 6b5da66322c5 ("ASoC: rt5645: read jd1_1 status for jd detection"). This changes the jd_mode for buddy to 4 so buddy can read from the same register that was used in the working version of this driver without affecting any other devices that might use this, since no other device uses jd_mode = 4. To test this I plugged and uplugged the headphone jack, verifying audio works.

2019-11-11ASoC: rt5677: Disable irq at suspendBen Zhang
The irq is disabled at suspend to avoid running the threaded irq handler after the codec has been powered off. At resume, codec irq is re-enabled and the interrupt status register is checked to see if headphone has been pluggnd/unplugged while the device is suspended. There is still a chance that the headphone gets enabled or disabled after the codec is suspended. disable_irq syncs the threaded irq handler, but soc-jack's threaded irq handler schedules a delayed work to poll gpios (for debounce). This is still OK. The codec won't be powered back on again because all audio paths have been suspended, and there are no force enabled supply widgets (MICBIAS1 is disabled). The gpio status read after codec power off could be wrong, so the gpio values are checked again after resume.

2019-11-11ASoC: rt5677: Stop and restart DSP over suspend/resumeBen Zhang
MCLK1 gets disabled at suspend and re-enabled at resume. Before MCLK1 is re-enabled, if the DSP is already on (either the DSP was left on during suspend, or the DSP is turned on early at resume), i2c register read returns garbage and corrupts the regmap cache. This patch stops the DSP before suspend and restarts it after resume with a dalay to ensure MCLK is on while loading firmware.

2019-11-11ASoC: rt5677: Mark reg RT5677_PWR_ANLG2 as volatileBen Zhang
The codec dies when RT5677_PWR_ANLG2(MX-64h) is set to 0xACE1 while it's streaming audio over SPI. The DSP firmware turns on PLL2 (MX-64 bit 8) when SPI streaming starts. However regmap does not believe that register can change by itself. When BST1 (bit 15) is turned on with regmap_update_bits(), it doesn't read the register first before write, so PLL2 power bit is cleared by accident. Marking MX-64h as volatile in regmap solved the issue.

2019-11-11ASoC: rt5677: Enable jack detect while DSP is runningBen Zhang
Before a hotword is detected, GPIO1 pin is configured as IRQ output so that jack detect works. When a hotword is detected, the DSP firmware configures the GPIO1 pin as GPIO1 and drives a 1. rt5677_irq() is called after a rising edge on the GPIO1 pin, due to either jack detect event or hotword event, or both. All possible events are checked and handled in rt5677_irq() where GPIO1 pin is configured back to IRQ output if a hotword is detected.

2019-11-11ASoC: rt5677: Load firmware via SPI using delayed workBen Zhang
The firmware rt5677_elf_vad is an ELF binary obtained from request_firmware(). Sections of the ELF are loaded to the DSP via SPI. A model (e.g. en_us.mmap) can optionally be loaded to the DSP at RT5677_MODEL_ADDR to overwrite the baked-in model in rt5677_elf_vad. Then we switch to DSP mode, load firmware, and let DSP run. When a hotword is detected, an interrupt is fired and rt5677_irq() is called. When 'DSP VAD Switch' is turned off, the codec is set back to normal mode. The kcontrol 'DSP VAD Switch' is automatically enabled/disabled when the hotwording PCM stream is opened/closed.

2019-11-04ASoC: hdac_hda: fix race in device removalKai Vehmanen
When ASoC card instance is removed containing a HDA codec, hdac_hda_codec_remove() may run in parallel with codec resume. This will cause problems if the HDA link is freed with snd_hdac_ext_bus_link_put() while the codec is still in middle of its resume process. To fix this, change the order such that pm_runtime_disable() is called before the link is freed. This will ensure any pending runtime PM action is completed before proceeding to free the link. This issue can be easily hit with e.g. SOF driver by loading and unloading the drivers.

2019-10-22ASoC: rt5677: Add a PCM device for streaming hotword via SPIBen Zhang
This patch implements a PCM interface for streaming hotword phrases over SPI. Userspace can open the PCM device at anytime. The stream is blocked when no hotword is detected. The mic audio buffer on the DSP is a ~128KByte ring buffer that holds ~4sec of audio samples recorded from the DMIC (S16_LE, mono, 16KHz). After a hotword is detected, previous 2 seconds of audio (containing the detected hotword) is streamed first, then live capture continues until userspace closes the PCM stream. When transferring, copy one period at a time then call snd_pcm_period_elapsed(). This reduces the latency of transferring the initial ~2sec of audio after hotword detect since audio samples are available for userspace earlier.
