2020-09-07ASoC: sun8i-codec: Attach the bus clock to the regmapSamuel Holland1-19/+2
When attached to the regmap, the bus clock is automatically enabled as needed to access device registers. This avoids needing code to manage it separately in the driver.

<samuel@sholland.org>: This series fixes a couple of issues with the digital audio codec in the Allwinner A64 SoC: 1) Left/right channels were swapped when playing/recording audio 2) DAPM topology was wrong, breaking some kcontrols This is the minimum set of changes necessary to fix these issues in a backward-compatible way. For that reason, some DAPM widgets still have incorrect or confusing names; those and other issues will be fixed in later patch sets.

2020-08-17ASoC: sun50i-codec-analog: Enable DAPM for earpiece switchSamuel Holland1-6/+11
By including the earpiece mute switch in the DAPM graph, both the earpiece amplifier and the Mixer/DAC inputs can be powered off when the earpiece is muted. While the widget is really just a simple switch, it is represented as a "mixer with named controls" to avoid including the widget name in the kcontrol name. Otherwise, it is not possible to give the widget an accurate, descriptive name without changing the kcontrol name seen by userspace (which should be stable). The mute switch is between the source selection and the amplifier, as per the diagram in the SoC manual.

By including the line out mute switch in the DAPM graph, the Mixer/DAC inputs can be powered off when the line output is muted. The line outputs have an unusual routing scheme. The left side mute switch is between the source selection and the amplifier, as usual. The right side source selection comes *after* its amplifier (and after the left side amplifier), and its mute switch controls whichever source is currently selected.

The same enable bits are currently used for both the "Left/Right ADC" and the "Left/Right ADC Mixer" widgets. This happens to work in practice because the widgets are always enabled/disabled at the same time, but each register bit should only be associated with a single widget. To keep symmetry with the DAC widgets, keep the bits on the ADC widgets, and remove them from the ADC Mixer widgets.

2020-08-17ASoC: sun8i-codec: Add missing mixer routesSamuel Holland1-0/+6
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.

2020-08-17ASoC: sun8i-codec: Fix DAPM to match the hardware topologySamuel Holland1-25/+95
The A33/A64 digital codec has 4 physical inputs and 4 physical outputs: 3 AIFs/DAIs and one ADC/DAC pair. Internal routing is accomplished by a 4-channel mixer connected to each output. The analog and digital sides of the ADC/DAC are in separate ASoC components, so card-level DAPM routes (provided in the device tree) are necessary to connect them together. Currently, these routes are wrong. For AIF1 Playback, the correct topology is: ||<<============ sun8i-codec ===========>>|| || || CPU DAI -> AIF1 DA0 -> DAC Mixer -> DAC (digital) -> DAC (analog) || || but the driver and device trees currently describe: || || CPU DAI -> AIF1 DA0 -------------------------------> DAC (analog) || \--> DAC Mixer -> ??? [dead end] || For AIF1 Capture, there is an additional problem, because the Mixer route is backward. The topology should be: || || ADC (analog) -> ADC (digital) -> AIF1 AD0 Mixer -> AIF1 AD0 -> CPU DAI || || but the driver and device trees currently describe: || || ADC (analog) -> AIF1 AD0 ------------------------------------> CPU DAI || \--> ADC Mixer -> ??? [dead end] || The ADC/DAC are only powered because AIF1 AD0 (capture) has supply routes from the ADC, and AIF1 DA0 (playback) has supply routes from the DAC. However, neither set of supply routes matches the hardware topology. Audio can be routed among AIF1/2/3 without using the ADC or DAC at all; and audio can be routed from the ADC to the DAC without using any AIFs (via the "ADC Digital DAC Playback Switch"). Because the DAPM routes are wrong, both of these use cases are currently broken. This commit adds the necessary widgets and routes to represent the real hardware topology, with functionality equivalent to the current driver. For the existing "allwinner,sun8i-a33-codec" compatible, widgets with the old names are kept as wrappers around the new widgets, so existing device trees will continue to work. For "allwinner,sun50i-a64-codec", the old widgets can be omitted, because no device trees yet use that compatible.

2019-08-27ASoC: sunxi: Revert initial A83t supportMaxime Ripard1-1/+24
This reverts commit 3e9acd7ac6933c (ASoC: sun4i-i2s: Remove duplicated quirks structure"). It turns out that while one I2S controller is described in the A83t datasheet, the driver supports another, undocumented, one that has been inherited from the older SoCs, while the documented one uses the new design.

2019-08-21ASoC: sun4i-i2s: Add support for DSP formatsMaxime Ripard1-9/+35
In addition to the I2S format, the controller also supports the DSP_* formats. This requires some extra care on the LRCK period calculation, since the controller, with the PCM formats, require that the value set is no longer the periods of LRCK for a single channel, but for all of them. Let's add the code to deal with this, and support the DSP_A and DSP_B formats.

2019-08-21ASoC: sun4i-i2s: Use the actual format width instead of an hardcoded oneMaxime Ripard1-1/+1
The LRCK period field in the FMT0 register holds the number of LRCK period for one channel in I2S mode. This has been hardcoded to 32, while it really should be the physical width of the format, which creates an improper clock when using a 16bit format, with the i2s controller as LRCK master.

2019-08-21ASoC: sun4i-i2s: Use the physical / slot width for the clocksMaxime Ripard1-5/+7
The clock dividers function has been using the word size to compute the clock rate at which it's supposed to be running, but the proper formula would be to use the physical width and / or slot width in TDM. It doesn't make any difference at the moment since all the formats supported have the same sample width and physical width, but it's not going to last forever.

The LRCK and BCLK polarity offsets on newer SoCs has been changed, yet the driver didn't take it into account for all of them. This was taken into account for the H3, but not the A83t. This was handled using a reg_field for the H3. However, the value in that field will not be the same, so reg_field is not adapted in that case. Let's change for proper calls with the regular values.

From: Marcus Cooper <codekipper@gmail.com> The clock division dividers have changed between the older (A10/A31) and newer (H3, A64, etc) SoCs. While this was addressed through an offset on some SoCs, it was missing some dividers as well, so the support wasn't perfect. Let's introduce a pointer in the quirk structure for the divider calculation functions to use so we can have the proper range now.

On the first generation of Allwinner SoCs (A10-A31), the i2s controller was using the MCLK as BCLK parent.
