Subject: [PATCH 2/4] Documentation: dt-bindings: move exynos-adc.txt to more
iio/adc/
The DT bindings in exynos-adc.txt applies to the ADC
driver (exynos-adc.c) developed based on IIO framework.
The bindings are more appropriate to be under
Documentation/devicetree/bindings/iio/adc/

-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 exynos4412/5250 controllers.
- Must be "samsung,exynos-adc-v2" for
- future controllers.
- Must be "samsung,exynos3250-adc-v2" for
- for controllers compatible with ADC of
- Exynos3250.
-- reg: Contains ADC register address range (base address and
- length) and the address of the phy enable register.
-- 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" : ADC special clock (only for Exynos3250
- and compatible ADC block)
-- vdd-supply VDD input supply.
