6
7Required properties:
8- compatible : Should be "dlg,da7219"
9- reg: Specifies the I2C slave address
10
11- interrupt-parent : Specifies the phandle of the interrupt controller to which
12  the IRQs from DA7219 are delivered to.
13- interrupts : IRQ line info for DA7219.
14  (See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt for
15   further information relating to interrupt properties)
16
17- VDD-supply: VDD power supply for the device
18- VDDMIC-supply: VDDMIC power supply for the device
19- VDDIO-supply: VDDIO power supply for the device
20  (See Documentation/devicetree/bindings/regulator/regulator.txt for further
21   information relating to regulators)
22
23Optional properties:
24- interrupt-names : Name associated with interrupt line. Should be "wakeup" if
25  interrupt is to be used to wake system, otherwise "irq" should be used.
26- wakeup-source: Flag to indicate this device can wake system (suspend/resume).
27
28- clocks : phandle and clock specifier for codec MCLK.
29- clock-names : Clock name string for 'clocks' attribute, should be "mclk".
30
31- dlg,ldo-lvl : Required internal LDO voltage (mV) level for digital engine
32	[<1050>, <1100>, <1200>, <1400>]
33- dlg,micbias-lvl : Voltage (mV) for Mic Bias
34	[<1800>, <2000>, <2200>, <2400>, <2600>]
35- dlg,mic-amp-in-sel : Mic input source type
36	["diff", "se_p", "se_n"]

44	[<2800>, <2900>]
45- dlg,micbias-pulse-time : Mic bias higher voltage pulse duration (ms)
46- dlg,btn-cfg : Periodic button press measurements for 4-pole jack (ms)
47	[<2>, <5>, <10>, <50>, <100>, <200>, <500>]
48- dlg,mic-det-thr : Impedance threshold for mic detection measurement (Ohms)
49	[<200>, <500>, <750>, <1000>]
50- dlg,jack-ins-deb : Debounce time for jack insertion (ms)
51	[<5>, <10>, <20>, <50>, <100>, <200>, <500>, <1000>]
52- dlg,jack-det-rate: Jack type detection latency (3/4 pole)
53	["32ms_64ms", "64ms_128ms", "128ms_256ms", "256ms_512ms"]
54- dlg,jack-rem-deb : Debounce time for jack removal (ms)
55	[<1>, <5>, <10>, <20>]
56- dlg,a-d-btn-thr : Impedance threshold between buttons A and D
57	[0x0 - 0xFF]
