Signed-off-by: Ryan Lee <ryans.lee@...log.com>
---
Changes from v1:
  Fixed a syntax error for the 'dt_binding_check' build.
  Removed unnecessary properties.
  Added description about SoundWire device ID of MAX98363
Changes from v2:
  Removed the legacy from i2c/i2s driver and added SoundWire device ID info.
  Added missing information about DAI.
Changes from v3:
  Modified the commit message. Removed "This patch"
  Converted uppercase hex to lowercase hex
  Dropped 'sound-name-prefix'.
  Added unevaluatedProperties instead of additionalProperties

+description:
+  The MAX98363 is a SoundWire input Class D mono amplifier that
+  supports MIPI SoundWire v1.2-compatible digital interface for
+  audio and control data.
+  SoundWire peripheral device ID of MAX98363 is 0x3*019f836300
+  where * is the peripheral device unique ID decoded from pin.
+  It supports up to 10 peripheral devices(0x0 to 0x9).
