* 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>;

		status = "disabled";

	};
