| * 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 */ |
| }; |
