From: Lucas Tanure tanureal@opensource.cirrus.com

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.

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.

Add a YAML DT binding document for this device.

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 SPI component incorporates a SPI controller interface for communication with other peripheral components.

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.

Changes since v6: - Move the tip detect code into an work queue to avoid more locking issues.

Thanks, Charles
