-Samsung Exynos Analog to Digital Converter bindings
-
-The devicetree bindings are for the new ADC driver written for
-Exynos4 and upward SoCs from Samsung.
-
-New driver handles the following
-1. Supports ADC IF found on EXYNOS4412/EXYNOS5250
- and future SoCs from Samsung
-2. Add ADC driver under iio/adc framework
-3. Also adds the Documentation for device tree bindings
-
-Required properties:
-- compatible: Must be "samsung,exynos-adc-v1"
- for Exynos5250 controllers.
- Must be "samsung,exynos-adc-v2" for
- future controllers.
- Must be "samsung,exynos3250-adc" for
- controllers compatible with ADC of Exynos3250.
- Must be "samsung,exynos4212-adc" for
- controllers compatible with ADC of Exynos4212 and Exynos4412.
- Must be "samsung,exynos7-adc" for
- the ADC in Exynos7 and compatibles
- Must be "samsung,s3c2410-adc" for
- the ADC in s3c2410 and compatibles
- Must be "samsung,s3c2416-adc" for
- the ADC in s3c2416 and compatibles
- Must be "samsung,s3c2440-adc" for
- the ADC in s3c2440 and compatibles
- Must be "samsung,s3c2443-adc" for
- the ADC in s3c2443 and compatibles
- Must be "samsung,s3c6410-adc" for
- the ADC in s3c6410 and compatibles
- Must be "samsung,s5pv210-adc" for
- the ADC in s5pv210 and compatibles
-- reg: List of ADC register address range
- - The base address and range of ADC register
- - The base address and range of ADC_PHY register (every
- SoC except for s3c24xx/s3c64xx ADC)
-- interrupts: Contains the interrupt information for the timer. The
- format is being dependent on which interrupt controller
- the Samsung device uses.
-- #io-channel-cells = <1>; As ADC has multiple outputs
-- clocks From common clock bindings: handles to clocks specified
- in "clock-names" property, in the same order.
-- clock-names From common clock bindings: list of clock input names
- used by ADC block:
- - "adc" : ADC bus clock
- - "sclk" : ADC special clock (only for Exynos3250 and
- compatible ADC block)
-- vdd-supply VDD input supply.
-
-- samsung,syscon-phandle Contains the PMU system controller node
- (To access the ADC_PHY register on Exynos5250/5420/5800/3250)
-Optional properties:
-- has-touchscreen: If present, indicates that a touchscreen is
- connected an usable.
-
-Note: child nodes can be added for auto probing from device tree.
-
-Example: adding device info in dtsi file
-
-adc: adc@12d10000 {
- compatible = "samsung,exynos-adc-v1";
- reg = <0x12D10000 0x100>;
- interrupts = <0 106 0>;
- #io-channel-cells = <1>;
- io-channel-ranges;
-
- clocks = <&clock 303>;
- clock-names = "adc";
-
- vdd-supply = <&buck5_reg>;
- samsung,syscon-phandle = <&pmu_system_controller>;
-};
-
-Example: adding device info in dtsi file for Exynos3250 with additional sclk
-
-adc: adc@126c0000 {
- compatible = "samsung,exynos3250-adc", "samsung,exynos-adc-v2;
- reg = <0x126C0000 0x100>;
- interrupts = <0 137 0>;
- #io-channel-cells = <1>;
- io-channel-ranges;
-
- clocks = <&cmu CLK_TSADC>, <&cmu CLK_SCLK_TSADC>;
- clock-names = "adc", "sclk";
-
- vdd-supply = <&buck5_reg>;
- samsung,syscon-phandle = <&pmu_system_controller>;
-};
-
-Example: Adding child nodes in dts file
-
-adc@12d10000 {
-
- /* NTC thermistor is a hwmon device */
- ncp15wb473@0 {
- compatible = "murata,ncp15wb473";
- pullup-uv = <1800000>;
- pullup-ohm = <47000>;
- pulldown-ohm = <0>;
- io-channels = <&adc 4>;
- };
-};
-
-Note: Does not apply to ADC driver under arch/arm/plat-samsung/
-Note: The child node can be added under the adc node or separately.
