2011-10-12ASoC: WM8903: Implement DMIC supportStephen Warren
In addition to the currently supported analog capture path, the WM8903 also supports digital mics. The analog and digital capture paths are exclusive; a mux is present to select the capture source. Logically, the mux exists to select the decimator's input, from either the ADC or DMIC block outputs. However, the ADC power domain also includes the DMIC interface. Consequently, this change represents the mux as existing immediately before the ADC, and selecting between the Input PGA and DMIC block outputs. An alternative might be to represent the mux in its correct location, and associate the ADC power enable controls with both the real ADC, and a fake ADC for the DMIC?

2011-09-22ASoC: Tegra: wm8903 machine driver: Allow re-insertion of moduleStephen Warren
Two issues were preventing module snd-soc-tegra-wm8903.ko from being removed and re-inserted: a) The speaker-enable GPIO is hosted by the WM8903 chip. This GPIO must be freed before snd_soc_unregister_card() is called, because that triggers wm8903.c:wm8903_remove(), which calls gpiochip_remove(), which then fails if any of the GPIOs are in use. To solve this, free all GPIOs first, so the code doesn't care where they come from. b) We need to call snd_soc_jack_free_gpios() to match the call to snd_soc_jack_add_gpios() during initialization. Without this, the call to snd_soc_jack_add_gpios() fails during any subsequent modprobe and initialization, since the GPIO and IRQ are already registered. In turn, this causes the headphone state not to be monitored, so the headphone is assumed not to be plugged in, and the audio path to it is never enabled.

2011-08-04CHROMIUM: ASoC: Tegra: Double-buffer DMA in HWStephen Warren
Avoid audio FIFO underflow due to DMA ISR latency. MODE_ONESHOT works like this: * CPU tells DMA HW to make a transfer . * DMA HW performs the transfer, fires an interrupt, and goes idle. * Interrupt latency (including e.g. LP2 exit time) is seen here. * DMA driver ISR programs the next transfer, from a SW transfer queue. In that model, the interrupt latency must be hidden by the I2S FIFO, which is 16 samples IIRC, i.e. a very short time (~0.3mS @ 48KHz). MODE_CONTINUOUS_SINGLE works like this: * CPU tells DMA HW to make a transfer . * CPU tells DMA HW to make a second transfer. * DMA HW performs the transfer, fires an interrupt, and starts the second transfer immediately. * DMA driver ISR programs the next (third) transfer, while the second is in progress, from a SW transfer queue. Thus any DMA ISR latency is seen between transfer N completing and transfer N+2 starting (rather than N+1), since the HW itself already knows how to perform transfer N+1 before transfer N completes. Hence, the system is tolerant of much larger latencies.
