* Broadcom's IPROC Static ADC controller
|
|
|
|
Broadcom iProc ADC controller has 8 channels 10bit ADC.
|
|
Allows user to convert analog input voltage values to digital.
|
|
|
|
Required properties:
|
|
|
|
- compatible: Must be "brcm,iproc-static-adc"
|
|
|
|
- adc-syscon: Handler of syscon node defining physical base address of the
|
|
controller and length of memory mapped region.
|
|
|
|
- #io-channel-cells = <1>; As ADC has multiple outputs
|
|
refer to Documentation/devicetree/bindings/iio/iio-bindings.txt for details.
|
|
|
|
- io-channel-ranges:
|
|
refer to Documentation/devicetree/bindings/iio/iio-bindings.txt for details.
|
|
|
|
- clocks: Clock used for this block.
|
|
|
|
- clock-names: Clock name should be given as tsc_clk.
|
|
|
|
- interrupts: interrupt line number.
|
|
|
|
For example:
|
|
|
|
ts_adc_syscon: ts_adc_syscon@180a6000 {
|
|
compatible = "brcm,iproc-ts-adc-syscon","syscon";
|
|
reg = <0x180a6000 0xc30>;
|
|
};
|
|
|
|
adc: adc@180a6000 {
|
|
compatible = "brcm,iproc-static-adc";
|
|
adc-syscon = <&ts_adc_syscon>;
|
|
#io-channel-cells = <1>;
|
|
io-channel-ranges;
|
|
clocks = <&asiu_clks BCM_CYGNUS_ASIU_ADC_CLK>;
|
|
clock-names = "tsc_clk";
|
|
interrupts = <GIC_SPI 164 IRQ_TYPE_LEVEL_HIGH>;
|
|
};
