Dialog Semiconductor DA7219 Audio Codec bindings
|
|
|
|
DA7219 is an audio codec with advanced accessory detect features.
|
|
|
|
======
|
|
|
|
Required properties:
|
|
- compatible : Should be "dlg,da7219"
|
|
- reg: Specifies the I2C slave address
|
|
|
|
- interrupts : IRQ line info for DA7219.
|
|
(See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt for
|
|
further information relating to interrupt properties)
|
|
|
|
- VDD-supply: VDD power supply for the device
|
|
- VDDMIC-supply: VDDMIC power supply for the device
|
|
- VDDIO-supply: VDDIO power supply for the device
|
|
(See Documentation/devicetree/bindings/regulator/regulator.txt for further
|
|
information relating to regulators)
|
|
|
|
Optional properties:
|
|
- interrupt-names : Name associated with interrupt line. Should be "wakeup" if
|
|
interrupt is to be used to wake system, otherwise "irq" should be used.
|
|
- wakeup-source: Flag to indicate this device can wake system (suspend/resume).
|
|
|
|
- #clock-cells : Should be set to '<0>', only one clock source provided;
|
|
- clock-output-names : Name given for DAI clocks output;
|
|
|
|
- clocks : phandle and clock specifier for codec MCLK.
|
|
- clock-names : Clock name string for 'clocks' attribute, should be "mclk".
|
|
|
|
- dlg,micbias-lvl : Voltage (mV) for Mic Bias
|
|
[<1600>, <1800>, <2000>, <2200>, <2400>, <2600>]
|
|
- dlg,mic-amp-in-sel : Mic input source type
|
|
["diff", "se_p", "se_n"]
|
|
|
|
Deprecated properties:
|
|
- dlg,ldo-lvl : Required internal LDO voltage (mV) level for digital engine
|
|
(LDO unavailable in production HW so property no longer required).
