-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

-			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
-

-	clock-names = "adc";
-
-	vdd-supply = <&buck5_reg>;
-	samsung,syscon-phandle = <&pmu_system_controller>;

-

-STMicroelectronics STM32 Low-Power Timer Trigger
-
-STM32 Low-Power Timer provides trigger source (LPTIM output) that can be used
-by STM32 internal ADC and/or DAC.
-
-Must be a sub-node of an STM32 Low-Power Timer device tree node.
-See ../mfd/stm32-lptimer.txt for details about the parent node.
-
-Required properties:
-- compatible:		Must be "st,stm32-lptimer-trigger".
-- reg:			Identify trigger hardware block. Must be 0, 1 or 2
-			respectively for lptimer1, lptimer2 or lptimer3
-			trigger output.
-
-Example:
-	timer@40002400 {
-		compatible = "st,stm32-lptimer";
-		...
-		trigger@0 {
-			compatible = "st,stm32-lptimer-trigger";
-			reg = <0>;
-		};
-	};
