max98926 audio CODEC
This device supports I2C.
Required properties:
- compatible : "maxim,max98926"
- vmon-slot-no : slot number used to send voltage information
or in inteleave mode this will be used as
interleave slot.
- imon-slot-no : slot number used to send current information
- interleave-mode : When using two MAX98926 in a system it is
possible to create ADC data that that will
overflow the frame size. Digital Audio Interleave
mode provides a means to output VMON and IMON data
from two devices on a single DOUT line when running
smaller frames sizes such as 32 BCLKS per LRCLK or
48 BCLKS per LRCLK.
- reg : the I2C address of the device for I2C
Example:
codec: max98926@1a {
compatible = "maxim,max98926";
vmon-slot-no = <0>;
imon-slot-no = <2>;
reg = <0x1a>;
};
