The communication between MT6359 and SoC is through Mediatek PMIC wrapper.
For more detail, please visit Mediatek PMIC wrapper documentation.
Must be a child node of PMIC wrapper.
properties:
mediatek,dmic-mode:
$ref: /schemas/types.yaml#/definitions/uint32
description: |
Indicates how many data pins are used to transmit two channels of PDM
signal. 0 means two wires, 1 means one wire. Default value is 0.
enum:
- 0 # one wire
- 1 # two wires
mediatek,mic-type-0:
$ref: /schemas/types.yaml#/definitions/uint32
description: |
Specifies the type of mic type connected to adc0
enum:
- 0 # IDLE - mic in turn-off status
- 1 # ACC - analog mic with alternating coupling
- 2 # DMIC - digital mic
- 3 # DCC - analog mic with direct couping
- 4 # DCC_ECM_DIFF - analog electret condenser mic with differential mode
- 5 # DCC_ECM_SINGLE - analog electret condenser mic with single mode
