Subject: [PATCH v5 6/6] ASoC: cs42l43: Add support for the cs42l43
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.

No change since v4.
