+======
+Required properties: +- compatible : Should be "dlg,da7213" +- reg: Specifies the I2C slave address
+Optional properties: +- clocks : phandle and clock specifier for codec MCLK. +- clock-names : Clock name string for 'clocks' attribute, should be "mclk".
+- dlg,micbias1-lvl : Voltage (mV) for Mic Bias 1
[<1600>, <2200>, <2500>, <3000>]+- dlg,micbias2-lvl : Voltage (mV) for Mic Bias 2
[<1600>, <2200>, <2500>, <3000>]
Please append the units (-microvolt).
+- dlg,dmic-data-sel : DMIC channel select based on clock edge.
["lrise_rfall", "lfall_rrise"]+- dlg,dmic-samplephase : When to sample audio from DMIC.
["on_clkedge", "between_clkedge"]
How about boolean for these two.
+- dlg,dmic-clkrate : DMIC clock frequency (MHz).
[<1500000>, <3000000>]
So 1.5GHz or 3GHz?
Add units (-hz).
