Kernel-4.18.0-80.el8_spear-adc

  • 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 */
};
