* ST SPEAr ADC device driver
|
|
|
|
Required properties:
|
|
- compatible: Should be "st,spear600-adc"
|
|
- reg: Address and length of the register set for the device
|
|
- interrupt-parent: Should be the phandle for the interrupt controller
|
|
that services interrupts for this device
|
|
- interrupts: Should contain the ADC interrupt
|
|
- sampling-frequency: Default sampling frequency
|
|
|
|
Optional properties:
|
|
- vref-external: External voltage reference in milli-volts. If omitted
|
|
the internal voltage reference will be used.
|
|
- average-samples: Number of samples to generate an average value. If
|
|
omitted, single data conversion will be used.
|
|
|
|
Examples:
|
|
|
|
adc: adc@d8200000 {
|
|
compatible = "st,spear600-adc";
|
|
reg = <0xd8200000 0x1000>;
|
|
interrupt-parent = <&vic1>;
|
|
interrupts = <6>;
|
|
sampling-frequency = <5000000>;
|
|
vref-external = <2500>; /* 2.5V VRef */
|
|
};
