+Required properties:
+
+ - compatible : "cirrus,cs42l52"
+
+ - reg : the I2C address of the device for I2C
+
+Optional properties:
+
+ - reset-gpio : GPIO controller's phandle and the number
+ of the GPIO used to reset the codec.
+ - chgfreq : Charge Pump Frequency values. Allowable values of
+ 0x00 through 0x0F.
+ Frequency = (64xFs)/(N+2)
+ - mica-cfg : MIC A single-ended or differential select.
+ 0x00 = Single-Ended
+ 0x01 = Differential
+ - micb-cfg : MIC B single-ended or differential select.
+ 0x00 = Single-Ended
+ 0x01 = Differential
+ - mica-sel : MIC A single ended input select. For Single-Ended
+ configuration, select which MIC to use.
+ 0x00 = MIC1
+ 0x01 = MIC2
+ - micb-sel : MIC B single ended input select. For Single-Ended
+ configuration, select which MIC to use.
+ 0x00 = MIC1
+ 0x01 = MIC2
+ - micbias-lvl: Set the output voltage level on the MICBIAS Pin
+ 0x00 = 0.5 x VA
+ 0x01 = 0.6 x VA
+ 0x02 = 0.7 x VA
+ 0x03 = 0.8 x VA
+ 0x04 = 0.83 x VA
+ 0x05 = 0.91 x VA
these properties should be cirrus, prefixed.
This is for a Cirrus CODEC, not related to the Cirrus ARM9. I didn't think
we would prefix for a binding on a codec. I thought that was only for
SOC/Platforms
