* ASoC: sun4i-i2s: Add support for the R329/D1 variantSamuel Holland2022-02-031-3/+37
| | | | | | | | | | | | | This adds a new set of quirks to set the right RX channel map. Since that is the only change to the register layout, reuse the H6 regmap config by extending its last register. R329 support is added by its compatible string. D1 uses R329 as its fallback compatible, so no additional code change is needed for it.

* ASoC: sun4i-i2s: Update registers for more channelsSamuel Holland2022-02-031-11/+17
| | | | | | | | | | | | | | | | H6 expands the number of channels in each direction to 16, so the slot number fields need to be expanded from 3 to 4 bits each. R329/D1 expand that further by allowing each of the 16 slots to map to any of 4 data pins. For TX, the configuration of each pin is independent, so there is a copy of the mapping registers for each pin. For RX, each of the 16 slots can map to only one pin, so the registers were changed to add the pin selection inline with the channel mapping.

* ASoC: sun8i-codec: Add AIF, ADC, and DAC volume controlsSamuel Holland2021-11-291-0/+56
| | | | | | | | | | | | | | This allows changing the volume of each digital input/output independently, and provides the only "master volume" for the DAC. (The ADC also has a gain control on the analog side.) While the hardware supports digital gain up to +72dB, the controls here are limited to +24dB maximum, as any gain above that level makes volume sliders difficult to use, and is extremely likely to cause clipping.

| | | | | | | | | | | | | | | | | | | | | | | On the newer SoCs such as the H3 and A64 this is set by default to transfer a 0 after each sample in each slot. However the A10 and A20 SoCs that this driver was developed on had a default setting where it padded the audio gain with zeros. This isn't a problem while we have only support for 16bit audio but with larger sample resolution rates in the pipeline then SEXT bits should be cleared so that they also pad at the LSB. Without this the audio gets distorted. Set sign extend sample for all the sunxi generations even if they are not affected. This will keep consistency and avoid relying on default.

| | | | | | | | | | | | | | | | | | | | | | | As slots and slot_width can be set manually using set_tdm(). These values are then kept in sun4i_i2s struct. So we need to check if these values are set or not. This is not done actually and will trigger a bug. For example, if we set to the simple soundcard in the device-tree dai-tdm-slot-width = <32> and then start a stream using S16_LE, currently we would calculate BCLK for 32-bit slots, but program lrck_period for 16-bit slots, making the sample rate double what we expected. To fix this, we need to check if these values are set or not but as this logic is already done by the caller. Avoid duplicating this logic and just pass the required values as params to set_chan_cfg().

| | | | | | | | | | | | | | | | | | | | 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.

* ASoC: sun8i-codec: Automatically set the system sample rateSamuel Holland2020-10-261-19/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | The system sample rate programmed into the hardware is really a clock divider from SYSCLK to the ADC and DAC.

* ASoC: sun8i-codec: Enforce symmetric DAI parametersSamuel Holland2020-10-261-0/+3
| | | | | | | | | | | | | 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. Therefore, we need to enforce symmetry for these parameters, so starting a new substream will not break an existing substream.

* ASoC: sun8i-codec: Correct the BCLK divisor calculationSamuel Holland2020-10-261-8/+9
| | | | | | | | | | | | | | | | 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.

* ASoC: sun8i-codec: Round up the LRCK divisorSamuel Holland2020-10-261-10/+12
| | | | | | | | | | | | | | | | 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 LRCK inversion bit has a different meaning in DSP mode: it selects between the DSP A and DSP B formats. To support this, we need to know if the selected format is a DSP format. One easy way to do this is to set the format field before the clock inversion fields.

| | | | | | | | | | | | | | | | | | In preparation for adding additional DAIs to this component, convert the DAI driver definition to an array. Since this changes all of the lines in the definition anyway, let's move it closer to the ops function definitions, instead of on the far side of the DAPM arrays. And while moving the DAI driver ops, rename the set_fmt hook to match the usual naming scheme. Give the existing DAI an explicit ID and more meaningful stream names, so it will remain unique as more DAIs are added. The AIF widget streams must be updated to match.

* ASoC: sun8i-codec: Set up clock tree at probe timeSamuel Holland2020-10-051-19/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
