+ * "ti,adc12130"
+ * "ti,adc12132"
+ * "ti,adc12138"
+ - reg: SPI chip select number for the device
+ - interrupts: Should contain interrupt for EOC (end of conversion)
+ - clocks: phandle to conversion clock input
+ - spi-max-frequency: Definision as per
+ - vref-p-supply: The regulator supply for positive analog voltage reference
+ - vref-n-supply: The regulator supply for negative analog voltage reference
+ (Note that this must not go below GND or exceed vref-p)
+ If not specified, this is assumed to be analog ground.
+ - ti,acquisition-time: The number of conversion clock periods for the S/H's
+ acquisition time. Should be one of 6, 10, 18, 34. If not specified,
+ default value of 10 is used.
+ For high source impedances, this value can be increased to 18 or 34.
+ For less ADC accuracy and/or slower CCLK frequencies this value may be
+ decreased to 6. See section 6.0 INPUT SOURCE RESISTANCE in the
+ datasheet for details.
