2017-12-12ASoC: sun4i-codec: enable 12Khz and 24Khz audio sample ratesAndrea Bondavalli
H3 ASoC supports 12Khz and 24Khz audio sample rates but the current drivers doesn't advertise these rates properly and they cannot be used. For example attempt to capture at 12Khz uses 11Khz (same applies to audio playback): Recording raw data '/tmp/testS16_LE.raw' : Signed 16 bit Little Endian, Rate 12000 Hz, Stereo Warning: rate is not accurate (requested = 12000Hz, got = 11025Hz) This patch fixes the audio sample rates declared and supported by the driver according to the H3 data sheet. Specifically for audio playback: 8000, 11050, 12000, 16000, 22050, 24000, 32000, 44100, 48000, 96000, 192000 and for audio capture: 8000, 11050, 12000, 16000, 22050, 24000, 32000, 44100, 48000 Signed-off-by: Andrea Bondavalli <andrea.bondavalli74@gmail.com> Acked-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Mark Brown <broonie@kernel.org>
2017-11-09ASoC: sun4i-codec: fixed 32bit audio capture support for H3/H2+Andrea Bondavalli
32bit and 24bit audio capture formats for H3/H2+ are broken because the RX_SAMPLE_BITS and the RX_FIFO_MODE bits of AC_ADC_FIFOC register of the audio codec are not set to operate in 24bit mode but in 16bit mode only. The following patch sets the H3 audio codec registers and the DMA bus width properly when a 24/32bit capture is requested.

2017-08-21ASoC: sun4i-codec: Remove unnecessary function callDonglin Peng
First of all,the address of pdev->dev is assigned to card->dev in create_card,then the function platform_set_drvdata copies the value the variable card to pdev->dev.driver_data, but when calling snd_soc_register_card,the function dev_set_drvdata(card->dev, card) will also do the same copy operation,so i think that the former copy operation can be removed.

2017-07-19ASoC: sun4i: explicitly request exclusive reset controlPhilipp Zabel
Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting reset lines") started to transition the reset control request API calls to explicitly state whether the driver needs exclusive or shared reset control behavior. Convert all drivers requesting exclusive resets to the explicit API call so the temporary transition helpers can be removed. No functional changes.

This is supported by the sun8i-codec-analog driver, and tied into this codec driver with the audio card's aux_dev. In addition, the V3s does not have LINEIN, LINEOUT, MBIAS and MIC2, MIC3, and the FIFO related registers are like H3.

The A31 SoC's codec has various inputs, outputs and microphone bias supplies. These can be routed on the board in different ways, such as: - HPCOM may be connected to have the headphone DC coupled. - Microphones all use the MBIAS main microphone supply or one mic may use the HBIAS supply, which supports headset detection and buttons. - Line Out may be routed to an audio jack, or an onboard speaker amp with power controls.

The A31 internal codec has 3 microphone outputs, of which MIC2 and MIC3 are muxed internally. The resulting two microphone inputs have separate gain controls and mixer inputs. The codec also has 2 microphone bias pins. HBIAS is specifically for the headphone jack, which also supports headphone detection and control buttons. These extra functions are not supported yet. The other, MBIAS, is for all other analog microphones. There is also mention of digital microphone support, but documentation is scarce, and no hardware with it is available.

2016-11-03ASoC: sun4i-codec: Increase DMA max burst to 8Chen-Yu Tsai
According to the DMA engine API documentation, maxburst denotes the largest possible size of a single transfer, so as not to overflow destination FIFOs as explained in this excerpt from dmaengine.h * @src_maxburst: the maximum number of words (note: words, as in * units of the src_addr_width member, not bytes) that can be sent * in one burst to the device. Typically something like half the * FIFO depth on I/O peripherals so you don't overflow it. This * may or may not be applicable on memory sources. * @dst_maxburst: same as src_maxburst but for destination target * mutatis mutandis. The TX FIFO is 64 samples deep for stereo, and the RX FIFO is 16 samples deep. So maxburst could be 32 and 8 for TX and RX respectively. Unfortunately the sunxi DMA controller driver takes maxburst as the requested burst size, rather than a limit, and returns an error for unsupported values. The original value was 4, but some later SoCs do not officially support this burst size. This patch increases maxburst on the TX side to 8, which is supported by all variants of the sunxi DMA controller.

2016-11-03ASoC: sun4i-codec: Expand quirks to handle register offsets and card creationChen-Yu Tsai
The A31 has a similar codec to the A10/A20. The PCM parts are very similar, with just different register offsets. The analog paths are very different. There are more inputs and outputs. The A31s, A23, and H3 have a similar PCM interface, again with register offsets slightly rearranged. The analog path controls, while very similar between them and the A31, have been moved a separate bus which is accessed through a message box like interface in the PRCM address range. This would be handled by a separate auxiliary device tied in through the device tree in its supporting create_card function. The quirks structure is expanded to include different register offsets and separate callbacks for creating the ASoC card. The regmap_config, quirks, and of_device_match tables have been moved to facilitate this.

The audio codec on later Allwinner SoCs have a different layout and audio path compared to the A10/A20. However the PCM parts are still the same. The different layout and audio paths mean we need a different create_card function for different families, so they can create DAPM endpoint widgets and routes. This patch moves the regmap configs, quirks and of_device_id structures to just before the probe function, so we can, among other things, include a pointer for the create_card function. None of the lines of code were changed. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Acked-by: Maxime Ripard <maxime.ripard@free-electrons.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2016-11-01ASoC: sun4i-codec: Enable bus clock after getting GPIOChen-Yu Tsai
In the current probe function the GPIO is acquired after the codec's bus clock is enabled. However if it fails to acquire the GPIO due to a deferred probe, it does not disable the bus clock before bailing out. This would result in the clock being enabled multiple times. Move the code that enables the bus clock after the part that gets the GPIO, maintaining a separation between resource acquisition and device enablement in the probe function.

2016-10-31ASoC: sun4i-codec: return error code instead of NULL when create_card failsChen-Yu Tsai
When sun4i_codec_create_card fails, we do not assign a proper error code to the return value. The return value would be 0 from the previous function call, or we would have bailed out sooner. This would confuse the driver core into thinking the device probe succeeded, when in fact it didn't, leaving various devres based resources lingering. Make the create_card function pass back a meaningful error code, and assign it to the return value.

When this driver implements audio input, it'll also need to expose controls for the line and mic input preamps, so just referring to "the Pre-Amplifier" will be ambiguous.
