* Broadcom's IPROC Static ADC controller
2
3
Broadcom iProc ADC controller has 8 channels 10bit ADC.
4
Allows user to convert analog input voltage values to digital.
5
6
Required properties:
7
8
- compatible: Must be "brcm,iproc-static-adc"
9
10
- adc-syscon: Handler of syscon node defining physical base address of the
11
controller and length of memory mapped region.
12
13
- #io-channel-cells = <1>; As ADC has multiple outputs
14
refer to Documentation/devicetree/bindings/iio/iio-bindings.txt for details.
15
16
- io-channel-ranges:
17
refer to Documentation/devicetree/bindings/iio/iio-bindings.txt for details.
18
19
- clocks: Clock used for this block.
20
21
- clock-names: Clock name should be given as tsc_clk.
22
23
- interrupts: interrupt line number.
24
25
For example:
26
27
ts_adc_syscon: ts_adc_syscon@180a6000 {
28
compatible = "brcm,iproc-ts-adc-syscon","syscon";
29
reg = <0x180a6000 0xc30>;
30
};
31
32
adc: adc@180a6000 {
33
compatible = "brcm,iproc-static-adc";
34
adc-syscon = <&ts_adc_syscon>;
35
#io-channel-cells = <1>;
36
io-channel-ranges;
37
clocks = <&asiu_clks BCM_CYGNUS_ASIU_ADC_CLK>;
38
clock-names = "tsc_clk";
39
interrupts = <GIC_SPI 164 IRQ_TYPE_LEVEL_HIGH>;
40
};
