This adds support for using CS42L42 as a SoundWire device. SoundWire-specifics are kept separate from the I2S implementation as much as possible, aiming to limit the risk of breaking the I2C+I2S support. There are some important differences in the silicon behaviour between I2S and SoundWire mode that are reflected in the implementation: - ASP (I2S) most not be used in SoundWire mode because the two interfaces share pins. - The SoundWire capture (record) port only supports 1 channel. It does not have left-to-right duplication like the ASP. - DP2 can only be prepared if the HP has powered-up. DP1 can only be prepared if the ADC has powered-up. (This ordering restriction does not exist for ASPs.) The SoundWire core port-prepare step is triggered by the DAI-link prepare(). This happens before the codec DAI prepare() or the DAPM sequence so these cannot be used to enable HP/ADC. Instead the HP/ADC enable/disable are done during the port_prep callback. - The SRCs are an integral part of the audio chain but in silicon their power control is linked to the ASP. There is no equivalent power link to SoundWire DPs so the driver must take "manual" control of SRC power. - The SoundWire control registers occupy the lower part of the SoundWire address space so cs42l42 registers are offset by 0x8000 (non-paged) in SoundWire mode. - Register addresses are 8-bit paged in I2C mode but 16-bit unpaged in SoundWire. - Special procedures are needed on register read/writes to (a) ensure that the previous internal bus transaction has completed, and (b) handle delayed read results, when the read value could not be returned within the SoundWire read command. There are also some differences in driver implementation between I2S and SoundWire operation: - CS42L42 I2S does not runtime_suspend, but runtime_suspend/resume support has been added into the driver in SoundWire mode as the most convenient way to power-up the bus manager and to handle the unattach_request condition, though the CS42L42 chip does not itself suspend or resume. - Intel SoundWire host controllers have a low-power clock-stop mode that requires resetting all peripherals when resuming. This means that the interrupt registers will be reset in between the interrupt being generated and the interrupt being handled, and since the interrupt status is debounced, these values may not be accurate immediately, and may cause spurious unplug events before settling. - As in I2S mode, the PLL is only used while audio is active because of clocking quirks in the silicon. For SoundWire the cs42l42_pll_config() is deferred until the DAI prepare(), to allow the cs42l42_bus_config() callback to set the SCLK. Signed-off-by:

Setup of the ASP (audio serial port) was being done as a side-effect of cs42l42_pll_config() and forces a restriction on the ratio of sample_rate to bit_clock that is invalid for Soundwire. Move the ASP setup into a dedicated function. Signed-off-by:

The chosen clocking configuration must give an internal MCLK (MCLKint) that is an integer multiple of the sample rate. On I2S each of the supported bit clock frequencies can only be generated from one sample rate group (either the 44100 or the 48000) so the code could use only the bitclock to look up a PLL config. The relationship between sample rate and bitclock frequency is more complex on Soundwire and so it is possible to set a frame shape to generate a bitclock from the "wrong" group. For example 2*147 with a 48000 sample rate would give a bitclock of 14112000 which on I2S could only be derived from a 44100 sample rate. Signed-off-by:

Set the reserved bit 7 in the ANALOG_CTRL_REG for the TAS5720A-Q1 device, when probing. The datasheet mentions that the bit should be 1 during reset/powerup. The device did not initialize before setting this value to 1. So, this could be a quirk of this device. Or it could be a quirk with the board on which it was tested. That is why this patch is separate from the patch that adds support for the TAS5720A-Q1 device. Signed-off-by:

This change adds support the TAS5720A-Q1 audio codec, in the same driver as tas5720. Functionally, this driver is pretty similar to it's TAS5720x variant. The first 3 registers are the same, so the main control and device identification can happen with these registers. The next registers differ. This variant offers control (in the registers) for 2 speakers, which is implemented here (in a basic manner). Signed-off-by:

This is to be re-used in tas5720_mute() (which is part of the dai_ops) and also in the tas5720_fault_check_work() hook. The benefit here isn't too great (now). It's only when we add support for a new device with a slightly different regmap that this becomes more useful. Signed-off-by:

The shutdown GPIO is active low (SD_N), but this depends on actual board layout. Linux drivers should only care about logical state, where high (1) means shutdown and low (0) means do not shutdown. Invert the GPIO to match logical value while preserving backwards DTB compatibility. It is not possible to detect whether ACTIVE_HIGH flag in DTB is because it is an old DTB (using incorrect flag) or it is a new DTB with a correct hardware pin polarity description. Therefore the solution prioritizes backwards compatibility while relying on relevant DTS being upstreamed. Signed-off-by:

RT9120 uses PM runtime autosuspend to decrease the frequently on/off spent time. This exists one case, when pcm is closed and dev PM is waiting for autosuspend time expired to enter runtime suspend state. At the mean time, system is going to enter suspend, dev PM runtime suspend won't be called. It makes the rt9120 suspend consumption current not as expected. This patch can fix the rt9120 dev PM issue during runtime autosuspend and system suspend by binding dev PM runtime and ASoC component PM.

This patch enables support for internal wm8940's PLL and proper divider to set proper value for 256x fs clock. This approach is more flexible and replaces hardcoded clock values and makes the codec work with the simple-card driver. Card drivers calling set_pll() and set_clkdiv() directly are unaffected.
