PS4: 
I was comparing ALC 711 and ALC 722 (your CL) and felt that only change between those two drivers are .version, .part_id and .class.
Additionally, you can refactor the existing ALC 711 code to accommodate both codec (this will save the coding and review effort as well)

1.

```
static struct soundwire_address alc711_address = {
#if CONFIG(DRIVERS_SOUNDWIRE_ALC722)
    .version = SOUNDWIRE_VERSION_1_2,
    .class = MIPI_CLASS_SDCA
    .part_id = MIPI_DEV_ID_REALTEK_ALC722,
#elif CONFIG(DRIVERS_SOUNDWIRE_ALC711)
    .version = SOUNDWIRE_VERSION_1_1,
    .class = MIPI_CLASS_NONE
    .part_id = MIPI_DEV_ID_REALTEK_ALC711,
#else
#error "Select correct codec driver"
#endif
    .manufacturer_id = MIPI_MFG_ID_REALTEK,
};
```

2.

```
config DRIVERS_SOUNDWIRE_ALC_BASE_7XX
    bool
    help
      Base code for Realtek ALC7xxx Codec Soundwire Driver.

config DRIVERS_SOUNDWIRE_ALC711
    bool
    select DRIVERS_SOUNDWIRE_ALC_BASE_7XX
    Soundwire Driver for Realtek ALC711 device

config DRIVERS_SOUNDWIRE_ALC722
    bool
    select DRIVERS_SOUNDWIRE_ALC_BASE_7XX
    help
      Soundwire Driver for Realtek ALC722 device
      
```

```
ramstage-$(CONFIG_DRIVERS_SOUNDWIRE_ALC_BASE_7XX) += alc711.c
```
