mfd: cs42l43: Tidy up header includes

2024-02-23T14:58:01+00:00

Use more forward declarations, move header guards to cover other
includes, and rely less on including headers through other headers.

mfd: cs42l43: Correct SoundWire port list

2023-12-07T13:50:30+00:00

Two ports are missing from the port list, and the wrong port is set
to 4 channels. Also the attempt to list them by function is rather
misguided, there is nothing in the hardware that fixes a particular
port to one function. Factor out the port properties to an actual
struct, fixing the missing ports and correcting the port set to 4
channels.

mfd: cs42l43: Add support for cs42l43 core driver

2023-08-17T11:06:11+00:00

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 MFD component registers and initialises the device and provides
PM/system power management.
