-These devices support both I2C and SPI (configured with pin strapping

-
-Required properties:
-
- - compatible : "ti,pcm1862",
-                "ti,pcm1863",
-                "ti,pcm1864",

-
- - avdd-supply: Analog core power supply (3.3v)
- - dvdd-supply: Digital core power supply
- - iovdd-supply: Digital IO power supply
-        See regulator/regulator.txt for more information
-
-CODEC input pins:
- * VINL1
- * VINR1
- * VINL2
- * VINR2
- * VINL3
- * VINR3
- * VINL4
- * VINR4
-
-The pins can be used in referring sound node's audio-routing property.

+  amplifiers and support differential or single-ended analog inputs.
