+* Broadcom's IPROC Static ADC controller
+
+Required properties:
+
+- compatible: Must be "brcm,iproc-static-adc"
+
+- #address-cells: Specify the number of u32 entries needed in child nodes.
+ Should set to 1.
+
+- #size-cells: Specify number of u32 entries needed to specify child nodes size
+ in reg property. Should set to 1.
+
+- 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.
+
+- 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";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ 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";
+ };
