Dialog Semiconductor DA7218 Audio Codec bindings 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 (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-hz : DMic1 clock frequency (Hz). [<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-hz : DMic2 clock frequency (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-us : Time between jack detect measurements (us) [<5>, <10>, <20>, <40>, <80>, <160>, <320>, <640>] - dlg,jack-debounce : Number of debounce measurements taken for jack detect [<0>, <2>, <3>, <4>] - dlg,jack-threshold-pct : Threshold level for jack detection (% of VDD) [<84>, <88>, <92>, <96>] - dlg,comp-inv : Boolean flag, invert comparator output - dlg,hyst : Boolean flag, enable hysteresis - dlg,discharge : Boolean flag, auto discharge of Mic Bias on jack removal ====== Example: codec: da7218@1a { compatible = "dlg,da7218"; reg = <0x1a>; interrupt-parent = <&gpio6>; interrupts = <11 IRQ_TYPE_LEVEL_HIGH>; wakeup-source; VDD-supply = <®_audio>; VDDMIC-supply = <®_audio>; VDDIO-supply = <®_audio>; clocks = <&clks 201>; clock-names = "mclk"; dlg,micbias1-lvl-millivolt = <2600>; dlg,micbias2-lvl-millivolt = <2600>; dlg,mic1-amp-in-sel = "diff"; dlg,mic2-amp-in-sel = "diff"; dlg,dmic1-data-sel = "lrise_rfall"; dlg,dmic1-samplephase = "on_clkedge"; dlg,dmic1-clkrate-hz = <3000000>; dlg,dmic2-data-sel = "lrise_rfall"; dlg,dmic2-samplephase = "on_clkedge"; dlg,dmic2-clkrate-hz = <3000000>; da7218_hpldet { dlg,jack-rate-us = <40>; dlg,jack-debounce = <2>; dlg,jack-threshold-pct = <84>; dlg,hyst; }; };
