Mark Brown authored
Merge series from Richard Fitzgerald <rf@opensource.cirrus.com>: This adds support for I2S/TDM links where the slot width varies depending on the sample width, in a way that cannot be guessed by component hw_params(). A typical example is: - 16-bit samples use 16-bit slots - 24-bit samples use 32-bit slots There is no way for a component hw_params() to deduce from the information it is passed that 24-bit samples will be in 32-bit slots. Some audio hardware cannot support a fixed slot width or a slot width equal to the sample width in all cases. This is usually due either to limitations of the audio serial port or system clocking restrictions.

Merge series from Stephan Gerhold <stephan@gerhold.net>: This series adds a simple driver and DT schema for the Awinic AW8738 audio amplifier. It's fairly simple - the main difference to simple-amplifier is that there is a "one-wire pulse control" that allows configuring the amplifier to one of a few pre-defined modes. This can be used to configure the speaker-guard function (primarily the power limit for the amplifier).

DETECT_MODE and PLL_START must be zero while HP_PDN and ADC_PDN are both 1. If this condition is broken it can discharge FILT+ and it can then take up to 1 second for FILT+ to recharge. There is no workaround required for this, simply avoiding settings and sequences that would break the requirement. The driver already meets the requirement. But it is not obvious from reading the code that this requirement exists, or what is ensuring it is met. So it would not currently be obvious to someone changing the code that there is certain special behaviour that must be maintained. To avoid accidental breakage in the future: - Add comments into the register definitions to warn about this so that anyone changing the code around DETECT_MODE and PLL_START is aware of this requirement. - Add a comment where PLL_START is written to 1 to highlight the requirement and why it is satisfied. - Add a comment in cs42l42_setup_hs_type_detect() when DETECT_MODE is initialized.

The parts supported by this driver can have product-specific firmware and tunings files. Typically these have been used on embedded systems where the manufacturer is responsible for installing the correct product-specific firmware files into /lib/firmware. However, the linux-firmware repository places all available firmwares into /lib/firmware and it is up to the driver to select the correct product-specific firmware from that directory. For example a product containing four smart amplifiers may provide firmware specific for that product and each of the amplifiers may have coefficient files containing tunings for their placement in the mechanical design. This change extends firmware (wmfw) and coefficient (bin) filenames to be of the general form: <cirrus/>part-dspN-fwtype<-system_name<-asoc_component_prefix>>.type Where the cirrus subdirectory, system_name and asoc_component_prefix are optional. New files will be placed in the cirrus subdirectory to avoid polluting the main /lib/firmware/ location. The generic name must be searched in /lib/firmware before /lib/firmware/cirrus so that a generic file in the new location does not override existing product-specific files in the legacy location. The search order for firmware files is: - cirrus/part-dspN-fwtype-system_name-asoc_component_prefix.wmfw - cirrus/part-dspN-fwtype-system_name.wmfw - part-dspN-fwtype.wmfw - cirrus/part-dspN-fwtype.wmfw - Qualifications are added to the filename so that rightwards is more specific. - The system_name is provided by the codec driver. - The asoc_component_prefix is used to identify tunings for individual parts because it would already exist to disambiguate the controls and it makes it obvious which firmware file applies to which device. The optional coefficient file must have the same filename construction as the discovered wmfw except: - where the wmfw has only system_name then the bin file can optionally include the asoc_component_prefix. This is to allow a common wmfw for all amps but separate tunings per amp.

We have eleven machine drivers who make explicit references to gpios. Let's add the dependency. The use of 'depends on' instead of 'select' is intentional. On one side it could be argued that the GPIOs are required, but on the other it might create more issues with randconfig builds.

Some audio hardware cannot support the same slot width for all sample widths, or a slot width equal to the sample width for all sample widths. This is usually due either to limitations of the audio serial port or system clocking restrictions. A typical example would be: - 16-bit samples in 16-bit slots - 24-bit samples in 32-bit slots The new dai-tdm-slot-width-map property allows setting a mapping of sample widths and the corresponding tdm slot widths and slot counts. Although the slot count is usually the same for all cases this does allow for adding padding slots to maintain the same bitclk frequency. The property is added to each endpoint node that needs the component DAI to be told the TDM slot width and count.
