1 Freescale i.MX25 ADC GCQ device
3 This is a generic conversion queue device that can convert any of the
4 analog inputs using the ADC unit of the i.MX25.
7 - compatible: Should be "fsl,imx25-gcq".
8 - reg: Should be the register range of the module.
9 - interrupts: Should be the interrupt number of the module.
10 Typically this is <1>.
11 - interrupt-parent: phandle to the tsadc module of the i.MX25.
12 - #address-cells: Should be <1> (setting for the subnodes)
13 - #size-cells: Should be <0> (setting for the subnodes)
16 - vref-ext-supply: The regulator supplying the ADC reference voltage.
17 Required when at least one subnode uses the this reference.
18 - vref-xp-supply: The regulator supplying the ADC reference voltage on pin XP.
19 Required when at least one subnode uses this reference.
20 - vref-yp-supply: The regulator supplying the ADC reference voltage on pin YP.
21 Required when at least one subnode uses this reference.
24 Optionally you can define subnodes which define the reference voltage
25 for the analog inputs.
27 Required properties for subnodes:
28 - reg: Should be the number of the analog input.
37 Optional properties for subnodes:
38 - fsl,adc-refp: specifies the positive reference input as defined in
39 <dt-bindings/iio/adc/fsl-imx25-gcq.h>
40 - fsl,adc-refn: specifies the negative reference input as defined in
41 <dt-bindings/iio/adc/fsl-imx25-gcq.h>
46 compatible = "fsl,imx25-gcq";
47 reg = <0x50030800 0x60>;
48 interrupt-parent = <&tscadc>;
55 fsl,adc-refp = <MX25_ADC_REFP_INT>;
56 fsl,adc-refn = <MX25_ADC_REFN_NGND>;
