Dvf610-adc.txt7 - compatible: Should contain "fsl,vf610-adc"
8 - reg: Offset and length of the register set for the device
9 - interrupts: Should contain the interrupt for the device
10 - clocks: The clock is needed by the ADC controller, ADC clock source is ipg clock.
11 - clock-names: Must contain "adc", matching entry in the clocks property.
12 - vref-supply: The regulator supply ADC reference voltage.
15 - fsl,adck-max-frequency: Maximum frequencies according to datasheets operating
17 - Frequency in normal mode (ADLPC=0, ADHSC=0)
18 - Frequency in high-speed mode (ADLPC=0, ADHSC=1)
19 - Frequency in low-power mode (ADLPC=1, ADHSC=0)
