1 Dialog Semiconductor DA7218 Audio Codec bindings
3 DA7218 is an audio codec with HP detect feature.
8 - compatible : Should be "dlg,da7217" or "dlg,da7218"
9 - reg: Specifies the I2C slave address
11 - VDD-supply: VDD power supply for the device
12 - VDDMIC-supply: VDDMIC power supply for the device
13 - VDDIO-supply: VDDIO power supply for the device
14 (See Documentation/devicetree/bindings/regulator/regulator.txt for further
15 information relating to regulators)
18 - interrupt-parent: Specifies the phandle of the interrupt controller to which
19 the IRQs from DA7218 are delivered to.
20 - interrupts: IRQ line info for DA7218 chip.
21 (See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt for
22 further information relating to interrupt properties)
23 - interrupt-names : Name associated with interrupt line. Should be "wakeup" if
24 interrupt is to be used to wake system, otherwise "irq" should be used.
25 - wakeup-source: Flag to indicate this device can wake system (suspend/resume).
27 - clocks : phandle and clock specifier for codec MCLK.
28 - clock-names : Clock name string for 'clocks' attribute, should be "mclk".
30 - dlg,micbias1-lvl-millivolt : Voltage (mV) for Mic Bias 1
31 [<1200>, <1600>, <1800>, <2000>, <2200>, <2400>, <2600>, <2800>, <3000>]
32 - dlg,micbias2-lvl-millivolt : Voltage (mV) for Mic Bias 2
33 [<1200>, <1600>, <1800>, <2000>, <2200>, <2400>, <2600>, <2800>, <3000>]
34 - dlg,mic1-amp-in-sel : Mic1 input source type
35 ["diff", "se_p", "se_n"]
36 - dlg,mic2-amp-in-sel : Mic2 input source type
37 ["diff", "se_p", "se_n"]
38 - dlg,dmic1-data-sel : DMIC1 channel select based on clock edge.
39 ["lrise_rfall", "lfall_rrise"]
40 - dlg,dmic1-samplephase : When to sample audio from DMIC1.
41 ["on_clkedge", "between_clkedge"]
42 - dlg,dmic1-clkrate-hz : DMic1 clock frequency (Hz).
43 [<1500000>, <3000000>]
44 - dlg,dmic2-data-sel : DMic2 channel select based on clock edge.
45 ["lrise_rfall", "lfall_rrise"]
46 - dlg,dmic2-samplephase : When to sample audio from DMic2.
47 ["on_clkedge", "between_clkedge"]
48 - dlg,dmic2-clkrate-hz : DMic2 clock frequency (Hz).
49 [<1500000>, <3000000>]
50 - dlg,hp-diff-single-supply : Boolean flag, use single supply for HP
55 Optional Child node - 'da7218_hpldet' (DA7218 only):
58 - dlg,jack-rate-us : Time between jack detect measurements (us)
59 [<5>, <10>, <20>, <40>, <80>, <160>, <320>, <640>]
60 - dlg,jack-debounce : Number of debounce measurements taken for jack detect
62 - dlg,jack-threshold-pct : Threshold level for jack detection (% of VDD)
63 [<84>, <88>, <92>, <96>]
64 - dlg,comp-inv : Boolean flag, invert comparator output
65 - dlg,hyst : Boolean flag, enable hysteresis
66 - dlg,discharge : Boolean flag, auto discharge of Mic Bias on jack removal
