2019-11-11ASoC: rt5677: Set ADC clock to use PLL and enable ASRCCurtis Malainey1-0/+2
Use the PLL to kept the correct 24M clock rate so frequency shift does not occur when using the DSP VAD. Signed-off-by: Curtis Malainey <cujomalainey@chromium.org> Link: https://lore.kernel.org/r/20191106011335.223061-11-cujomalainey@chromium.org Signed-off-by: Mark Brown <broonie@kernel.org>
2019-11-11ASoC: rt5677: Disable irq at suspendBen Zhang1-0/+2
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 Zhang1-1/+2
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: Load firmware via SPI using delayed workBen Zhang1-1/+5
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.

2019-06-19ASoC: rt5677: clear interrupts by polarity flipBen Zhang1-1/+7
The rt5677 jack detection function has a requirement that the polarity of an interrupt be flipped after it fires in order to clear the interrupt. This patch implements an irq_chip with irq_domain directly instead of using regmap-irq, so that interrupt source line polarities can be flipped in the irq handler. The reason that this patch does not add this feature within regmap-irq is that future patches will add hotword detection support to this irq handler. Those patches will require adding additional logic that would not make sense to have in regmap-irq.

This patch moves the code to select the gpios for jack detection from rt5677_probe to rt5677_init_irq (called from rt5677_i2c_probe). It also sets some registers to fix bugs related to jack detection, and adds some constants and comments to make it easier to understand what certain register settings are controlling.
