Kernel-4.18.0-80.el8_fsl-imx25-tsadc

Freescale MX25 ADC/TSC MultiFunction Device (MFD)

This device combines two general purpose conversion queues one used for general
ADC and the other used for touchscreens.

Required properties:

  • compatible: Should be “fsl,imx25-tsadc”.
  • reg: Start address and size of the memory area of
                  the device
    
  • interrupts: Interrupt for this device
                 (See: ../interrupt-controller/interrupts.txt)
    
  • clocks: An ‘ipg’ clock (See: ../clock/clock-bindings.txt)
  • interrupt-controller: This device is an interrupt controller. It
                    controls the interrupts of both
                 conversion queues.
    
  • #interrupt-cells: Should be ‘<1>’.
  • #address-cells: Should be ‘<1>’.
  • #size-cells: Should be ‘<1>’.

This device includes two conversion queues which can be added as subnodes.
The first queue is for the touchscreen, the second for general purpose ADC.

Example:
tscadc: tscadc@50030000 {
compatible = “fsl,imx25-tsadc”;
reg = <0x50030000 0xc>;
interrupts = <46>;
clocks = <&clks 119>;
clock-names = “ipg”;
interrupt-controller;
#interrupt-cells = <1>;
#address-cells = <1>;
#size-cells = <1>;
ranges;

    tsc: tcq@50030400 {
        compatible = "fsl,imx25-tcq";
        reg = <0x50030400 0x60>;
        ...
    };

    adc: gcq@50030800 {
        compatible = "fsl,imx25-gcq";
        reg = <0x50030800 0x60>;
        ...
    };
};
