| * 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>; |
| }; |
