1* ST SPEAr ADC device driver 2 3Required properties: 4- compatible: Should be "st,spear600-adc" 5- reg: Address and length of the register set for the device 6- interrupt-parent: Should be the phandle for the interrupt controller 7 that services interrupts for this device 8- interrupts: Should contain the ADC interrupt 9- sampling-frequency: Default sampling frequency 10 11Optional properties: 12- vref-external: External voltage reference in milli-volts. If omitted 13 the internal voltage reference will be used. 14- average-samples: Number of samples to generate an average value. If 15 omitted, single data conversion will be used. 16 17Examples: 18 19 adc: adc@d8200000 { 20 compatible = "st,spear600-adc"; 21 reg = <0xd8200000 0x1000>; 22 interrupt-parent = <&vic1>; 23 interrupts = <6>; 24 sampling-frequency = <5000000>; 25 vref-external = <2500>; /* 2.5V VRef */ 26 }; 27
