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:

Currently, port_prep callback only has commands for PRE_PREP, PREP, and POST_PREP, which doesn't directly say whether this is for a prepare or deprepare call. Extend the command list enum to say whether the call is for prepare or deprepare aswell. Also remove SDW_OPS_PORT_PREP from sdw_port_prep_ops as this is unused, and update this enum to be simpler and more consistent with enum sdw_clk_stop_type. Note: Currently, the only users of SDW_OPS_PORT_POST_PREP are codec drivers sound/soc/codecs/wsa881x.c and sound/soc/codecs/wsa883x.c, both of which seem to assume that POST_PREP only occurs after a prepare, even though it would also have occurred after a deprepare. Since it doesn't make sense to mark the port prepared after a deprepare, changing the enum to separate PORT_DEPREP from PORT_PREP should make the check for PORT_PREP in those drivers be more logical.

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:
