Previously ACP SOF firmware used to enable the ACP external global interrupt register. This will restrict to report ACP host interrupts only after firmware loading is successful. This register needs to be set from host driver to handle other ACP interrupts(SoundWire Interrupts) before loading the ACP firmware. Add field for external interrupt enable register in acp descriptor structure and enable the external interrupt enable register.

During initial development time for RN platform, when SHA dma gets completed, SHA DMA engine used to raise the ACP interrupt. In ACP interrupt handler, SHA DMA interrupt got handled. Currently SHA DMA compleition is verified by checking transfer count using read poll time out logic. Remove unused SHA dma interrupt handling code.

Peter Ujfalusi authored
Add a new module parameter ipc4_ignore_cpc which can be used to force the kernel to ignore the queried CPC value for all firmware modules and use 0 instead. The CPC lookup is still done to report missing configurations and the debug print is going to be different to be explicit that the CPC is ignored and what was the value we would have used. The CPC value is sent to the firmware with the MOD_INIT_INSTANCE message and it is used by the firmware as a parameter for clock scaling. The flag is intended to be used only when there is a need to validate the firmware behavior regarding to clock scaling since the 0 CPC value will force the DSP to run in full speed, disabling the scaling and provides additional counter point to rule out clock management related issues.

The CS42L43 is an audio CODEC with integrated MIPI SoundWire interface (Version 1.2.1 compliant), I2C, SPI, and I2S/TDM interfaces designed for portable applications. It provides a high dynamic range, stereo DAC for headphone output, two integrated Class D amplifiers for loudspeakers, and two ADCs for wired headset microphone input or stereo line input. PDM inputs are provided for digital microphones. The ASoC component provides the majority of the functionality of the device, all the audio functions.

Commit 7ac3404c ("ASoC: amd: acp: Map missing jack kcontrols") adds card kcontrols and DAPM widgets corresponding to jacks for Headphone and Headset Mic. But these were already being added in acp-legacy-mach.c and acp-sof-mach.c, so this causes a probe error: sof_mach rt5682s-hs-rt1019: control 2:0:0:Headphone Jack Switch:0 is already present sof_mach rt5682s-hs-rt1019: ASoC: Failed to add Headphone Jack Switch: -16 sof_mach rt5682s-hs-rt1019: devm_snd_soc_register_card(sof-rt5682s-hs-rt1019) failed: -16 sof_mach: probe of rt5682s-hs-rt1019 failed with error -16 Removing the new duplicates from the common code might be enough to fix the issue. But some of the codecs use different kcontrols and widgets. NAU8821 alone has an "Int Mic". MAX98360A has a single "Spk", while RT1019 has "Left Spk" and "Right Spk" (and two codec instances with name prefixes). Since there are per-codec differences, add the kcontrols and widgets in the common code as each dai-link is being initialized, instead of in the two machine drivers' probe(). Also, MAX98388 has Left and Right instances, but uses a single "SPK" widget. That seems weird, so normalize it to use two widgets (one per each instance like RT1019) while we're adding controls.

The RT5640 driver is already using GPIO descriptors for some stuff, all that is needed is to convert the remaining LDO1 control line to also use descriptors. Simplify the code using gpiod_get_optional() and drop the special "of" parsing function: these descriptors need not come from device tree and it's optional so hey. Keep some NULL checks around the GPIO operations even though gpiolib is essentially NULL-tolerant, because by checking for whether we have a valid GPIO descriptor or not we can avoid a 400 ms delay which is great.

Use a device property "cirrus,firmware-uid" to get the unique firmware identifier instead of using ACPI _SUB. There aren't any products that use _SUB. There will not usually be a _SUB in Soundwire nodes. The ACPI can use a _DSD section for custom properties. There is also a need to support instantiating this driver using software nodes. This is for systems where the CS35L56 is a back-end device and the ACPI refers only to the front-end audio device - there will not be any ACPI references to CS35L56.

Lucas Tanure authored
Currently the in-band alerts for SoundWire peripherals can only be communicated to the driver through the interrupt_callback function. This however is slightly inconvenient for devices that wish to share IRQ handling code between SoundWire and I2C/SPI, the later would normally register an IRQ handler with the IRQ subsystem. However there is no reason the SoundWire in-band IRQs can not also be communicated as an actual IRQ to the driver. Add support for SoundWire peripherals to register a normal IRQ handler to receive SoundWire in-band alerts, allowing code to be shared across control buses. Note that we allow users to use both the interrupt_callback and the IRQ handler, this is useful for devices which must clear additional chip specific SoundWire registers that are not a part of the normal IRQ flow, or the SoundWire specification.
