-Analog devices AS3645A device tree bindings
-
-The AS3645A flash LED controller can drive two LEDs, one high current
-flash LED and one indicator LED. The high current flash LED can be
-used in torch mode as well.
-
-Ranges below noted as [a, b] are closed ranges between a and b, i.e. a
-and b are included in the range.
-
-Please also see common.txt in the same directory.

-Required properties
-===================
-
-compatible	: Must be "ams,as3645a".
-reg		: The I2C address of the device. Typically 0x30.
-#address-cells	: 1
-#size-cells	: 0
-
-
-Required properties of the flash child node (0)
-===============================================
-
-reg: 0
-flash-timeout-us: Flash timeout in microseconds. The value must be in
-		  the range [100000, 850000] and divisible by 50000.
-flash-max-microamp: Maximum flash current in microamperes. Has to be
-		    in the range between [200000, 500000] and
-		    divisible by 20000.
-led-max-microamp: Maximum torch (assist) current in microamperes. The
-		  value must be in the range between [20000, 160000] and
-		  divisible by 20000.
-ams,input-max-microamp: Maximum flash controller input current. The
-			value must be in the range [1250000, 2000000]
-			and divisible by 50000.

-color		:  See Documentation/devicetree/bindings/leds/common.txt.
-label		:  See Documentation/devicetree/bindings/leds/common.txt (deprecated).
-
-
-Required properties of the indicator child node (1)
-===================================================
-
-reg: 1
-led-max-microamp: Maximum indicator current. The allowed values are
-		  2500, 5000, 7500 and 10000.
