1* Broadcom's IPROC Static ADC controller 2 3Broadcom iProc ADC controller has 8 channels 10bit ADC. 4Allows user to convert analog input voltage values to digital. 5 6Required 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 25For 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 }; 41
