ASoC: dt-bindings: Convert maxim,max98925 to DT schema
Convert the Maxim Integrated MAX98925/MAX98926/MAX98927 speaker amplifier bindings to DT schema format. Changes during conversion: 1. Add "sound-dai-cells", already used by DTS. 2. Use "maxim,interleave-mode" instead previous "interleave-mode" and undocumented but used interleave_mode.

Maxim Integrated MAX98925/MAX98926/MAX98927 Speaker Amplifier
|
||||
|
||||
This device supports I2C.
|
||||
|
||||
Required properties:
|
||||
|
||||
- compatible : should be one of the following
|
||||
- "maxim,max98925"
|
||||
- "maxim,max98926"
|
||||
- "maxim,max98927"
|
||||
|
||||
- vmon-slot-no : slot number used to send voltage information
|
||||
or in inteleave mode this will be used as
|
||||
interleave slot.
|
||||
MAX98925/MAX98926 slot range : 0 ~ 30, Default : 0
|
||||
MAX98927 slot range : 0 ~ 15, Default : 0
|
||||
|
||||
- imon-slot-no : slot number used to send current information
|
||||
MAX98925/MAX98926 slot range : 0 ~ 30, Default : 0
|
||||
MAX98927 slot range : 0 ~ 15, Default : 0
|
||||
|
||||
- interleave-mode : When using two MAX9892X 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.
|
||||
Range : 0 (off), 1 (on), Default : 0
|
||||
|
||||
- reg : the I2C address of the device for I2C
|
||||
|
||||
Optional properties:
|
||||
- reset-gpios : GPIO to reset the device
|
||||
|
||||
Example:
|
||||
|
||||
codec: max98927@3a {
|
||||
compatible = "maxim,max98927";
|
||||
vmon-slot-no = <0>;
|
||||
imon-slot-no = <1>;
|
||||
interleave-mode = <0>;
|
||||
reg = <0x3a>;
|
||||
};
