2024-09-09ASoC: Switch back to struct platform_driver::remove()Uwe Kleine-König
After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all drivers below sound/soc to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

2024-03-25ASoC: sun8i-codec: Implement jack and accessory detectionArnaud Ferraris
Add support for the jack detection functionality in the A64 variant, which uses a pair of IRQs; and microphone accessory (button) detection, which uses an ADC with an IRQ trigger. IRQs will only be triggered if the JACKDETEN, HMICBIASEN, and MICADCEN bits are set appropriately in the analog codec component (sun50i-codec-analog), but there is no direct software dependency between the two components. Setup ADC so that it samples with period of 16ms, disable smoothing and enable MDATA threshold (should be below idle voltage/HMIC_DATA value). Also enable HMIC_N, which makes sure we get HMIC_N samples after HMIC_DATA crosses the threshold. This allows us to perform steady state detection of HMIC_DATA, by comparing current and previous ADC samples, to detect end of the transient when the user de-presses the button. Otherwise ADC could sample anywhere within the transient, and the driver may mis-issue key-press events for other buttons attached to the resistor ladder.

2024-03-25ASoC: sun8i-codec: Enable bus clock at STANDBY and higher biasSamuel Holland
For codec variants that have a bus clock, that clock must be running to receive interrupts. Since jack and mic accessory detection should work even when no audio is playing, that means the bus clock should be enabled any time the system is on. Accomplish that by tying the bus clock to the runtime PM state, which is then tied to the bias level not being OFF. Since the codec sets idle_bias_on, bias will generally never be OFF. However, we can set suspend_bias_off to maintain the power savings of gating the bus clock during suspend, when we don't expect jack/accessory detection to work.

2023-10-09ASoC: Explicitly include correct DT includesRob Herring
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it was merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2023-03-20ASoC: sunxi: sun8i-codec: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2020-10-26ASoC: sun8i-codec: Add the AIF3 DAI, widgets, and routesSamuel Holland
AIF3 has some differences from AIF1 and AIF2: - It supports one channel only - It supports master mode only - It is not directly connected to any of the mixers; instead all audio goes through a mux with AIF2. - It does not have its own clock dividers; instead it reuses AIF2 BCLK and LRCK. This means that when both AIF2 and AIF3 are active, they must use the same sample rate and total frame width. Since AIF2 and AIF3 are only used for codec2codec DAI links, constraints are not applicable here; the only thing we can do when the rates don't match is report an error. Make the necessary adjustments to support this AIF.

2020-10-26ASoC: sun8i-codec: Automatically set the system sample rateSamuel Holland
The sun8i codec has three clock/sample rate domains: - The AIF1 domain, with a sample rate equal to AIF1 LRCK - The AIF2 domain, with a sample rate equal to AIF2 LRCK - The SYSCLK domain, containing the ADC, DAC, and effects (AGC/DRC), with a sample rate given by a divisor from SYSCLK. The divisor is controlled by the AIF1_FS or AIF2_FS field in SYS_SR_CTRL, depending on if SYSCLK's source is AIF1CLK or AIF2CLK, respectively. The exact sample rate depends on if SYSCLK is running at 22.6 MHz or 24.6 MHz. When an AIF (currently only AIF1) is active, the ADC and DAC should run at that sample rate to avoid artifacting. Sample rate conversion is only available when multiple AIFs are active and are routed to each other; this means the sample rate conversion hardware usually cannot be used. Only attach the event hook to the channel 0 AIF widgets, since we only need one event when a DAI stream starts or stops. Channel 0 is always brought up with a DAI stream, regardless of the number of channels in the stream. The ADC and DAC (along with their effects blocks) can be used even if no AIFs are in use. In that case, we should select an appropriate sample rate divisor, instead of keeping the last-used AIF sample rate. 44.1/48 kHz was chosen to balance audio quality and power consumption. Since the sample rate is tied to active AIF paths, disabling pmdown_time allows switching to the optimal sample rate immediately, instead of after a 5 second delay.

2020-10-26ASoC: sun8i-codec: Enforce symmetric DAI parametersSamuel Holland
The AIFs have a single register controlling DAI parameters in both directions, including BCLK/LRCK divisor and word size. The DAIs produce only noise or silence if any of these parameters is wrong.

Previously, the BCLK divisor calculation assumed zero padding and exactly two slots. In order to support the TDM slot binding and 20/24-bit word sizes, those assumptions must be removed. Due to hardware limitations, the BCLK/LRCK ratio is not as simple as "slot_width * slots". However, the correct value is already calculated elsewhere in this function, since it must also be programmed into the hardware. Reuse that value to calculate the correct SYSCLK/BCLK divisor.

The codec supports only power-of-two BCLK/LRCK divisors. If either the slot width or the number of slots is not a power of two, the LRCK divisor must be rounded up to provide enough space. To do that, use order_base_2 (instead of ilog2, which rounds down). Since the rounded divisor is also needed for setting the SYSCLK/BCLK divisor, return the order base 2 instead of fully calculating the hardware register encoding.

The sun8i codec is effectively an on-die variant of the X-Powers AC100 codec. The AC100 can derive its clocks from either of two I2S master clocks or an internal PLL. For the on-die variant, Allwinner replaced the codec's own PLL with a connection to SoC's existing PLL_AUDIO, and they connected both I2S MCLK inputs to the same source -- which happens to be an integer divider from the same PLL_AUDIO. So there's actually no clocking flexibility. To run SYSCLK at the required rate, it must be run straight from the PLL. The only choice is whether it goes through AIF1CLK or AIF2CLK. Since both run at the same rate, the only effect of that choice is which field in SYS_SR_CTRL (AIF1_FS or AIF2_FS) controls the system sample rate. Since AIFnCLK is required to bring up the corresponding DAI, and AIF1 (connected to the CPU) is used most often, let's use AIF1CLK as the SYSCLK parent. That means we no longer need to set AIF2_FS. Since this clock tree never changes, we can program it from the component probe function, instead of using DAPM widgets. The DAPM widgets unnecessarily change clock parents when the codec goes in/out of idle and the supply widgets are powered up/down.

2020-09-07ASoC: sun8i-codec: Manage module clock via DAPMSamuel Holland
By representing the module clock as a DAPM widget, we ensure that the clock is only enabled when the module is actually in use, without additional code in runtime PM hooks.

This driver is for the digital part of the codec only. The analog part, including the microphone inputs, is managed by a separate driver. These widgets look like they were copied from sun4i-codec.

Due to a mistake made while reordering patches, commit 90cac932976e ("ASoC: sun8i-codec: Fix DAPM to match the hardware topology") added the sun8i_codec_component_probe function without referencing it from the component definition. Add the reference so the probe function gets called as expected.

2020-08-17ASoC: sun8i-codec: Add a quirk for LRCK inversionSamuel Holland
On the A64, as tested using the PinePhone, the current code causes the left/right channels to be swapped during I2S playback from the CPU on AIF1, and breaks DSP_A communication with the modem on AIF2. Both of these are fixed when LRCK is no longer inverted. Trusting that the comment in the code is correct, the existing behavior is kept for the A33.

2020-08-17ASoC: sun8i-codec: Add missing mixer routesSamuel Holland
The sun8i-codec driver provides ALSA controls for enabling/disabling each of the inputs to the AIF1 Slot 0 and DAC mixers. For two of these inputs (ADC->DAC and AIF1 DA0->AIF1 AD0), the audio source is implemented, so the mixer inputs can be used. However, because the DAPM routes are missing, these mixer inputs only work when both the source and the mixer happen to be part of other active audio paths. Adding the appropriate routes makes these ALSA controls function all of the time.
