[PATCH v4 2/4] ASoC: dt-bindings: Add Airoha AN7581 AFE with WM8960 Codec schema

[Christian Marangi]

Add DT schema for Airoha AN7581 Sound Card with the specific WM8960 i2c Codec
and AFE as platform driver.

This gives example on how to define and connect the AFE driver with the
WM8960 for full functionality.
