+DA7218 is an audio codec with HP detect feature.
+======
+Required properties: +- compatible : Should be "dlg,da7217" or "dlg,da7218" +- reg: Specifies the I2C slave address
+- VDD-supply: VDD power supply for the device +- VDDMIC-supply: VDDMIC power supply for the device +- VDDIO-supply: VDDIO power supply for the device
These should be lower case (that is documented in ePAPR BTW :)).
- (See Documentation/devicetree/bindings/regulator/regulator.txt for further
- information relating to regulators)
+Optional properties: +- interrupt-parent: Specifies the phandle of the interrupt controller to which
- the IRQs from DA7218 are delivered to.
+- interrupts: IRQ line info for DA7218 chip.
- (See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt for
- further information relating to interrupt 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).
+- clocks : phandle and clock specifier for codec MCLK. +- clock-names : Clock name string for 'clocks' attribute, should be "mclk".
+- dlg,micbias1-lvl-millivolt : Voltage (mV) for Mic Bias 1
- [<1200>, <1600>, <1800>, <2000>, <2200>, <2400>, <2600>, <2800>, <3000>]
+- dlg,micbias2-lvl-millivolt : Voltage (mV) for Mic Bias 2
- [<1200>, <1600>, <1800>, <2000>, <2200>, <2400>, <2600>, <2800>, <3000>]
+- dlg,mic1-amp-in-sel : Mic1 input source type
- ["diff", "se_p", "se_n"]
+- dlg,mic2-amp-in-sel : Mic2 input source type
- ["diff", "se_p", "se_n"]
+- dlg,dmic1-data-sel : DMIC1 channel select based on clock edge.
- ["lrise_rfall", "lfall_rrise"]
+- dlg,dmic1-samplephase : When to sample audio from DMIC1.
- ["on_clkedge", "between_clkedge"]
+- dlg,dmic1-clkrate-hertz : DMic1 clock frequency (Hz).
-hz
Documenting the unit suffixes is on my todo list...
- [<1500000>, <3000000>]
+- dlg,dmic2-data-sel : DMic2 channel select based on clock edge.
- ["lrise_rfall", "lfall_rrise"]
+- dlg,dmic2-samplephase : When to sample audio from DMic2.
- ["on_clkedge", "between_clkedge"]
+- dlg,dmic2-clkrate-hertz : DMic2 clock frequency (Hz).
-hz
- [<1500000>, <3000000>]
+- dlg,hp-diff-single-supply : Boolean flag, use single supply for HP
(DA7217 only)+======
+Optional Child node - 'da7218_hpldet' (DA7218 only):
+Optional properties: +- dlg,jack-rate-microsecond : Time between jack detect measurements (us)
-us
Completely consistent, isn't it. Why we did -microvolt I don't know.
