+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.
+
+
+Required properties of the "flash" child node
+=
+
+flash-timeout-us: Flash timeout in microseconds. The value must be in
+ the range [10, 85] and divisible by 5.
+flash-max-microamp: Maximum flash current in microamperes. Has to be
+ in the range between [20, 50] and
+ divisible by 2.
+led-max-microamp: Maximum torch (assist) current in microamperes. The
+ value must be in the range between [2, 16] and
+ divisible by 2.
+ams,input-max-microamp: Maximum flash controller input current. The
+ value must be in the range [125, 200]
+ and divisible by 5.
+
+
+Optional properties of the "flash" child node
+=
+
+label : The label of the flash LED.
+
+
+Required properties of the "indicator" child node
+=
+
+led-max-microamp: Maximum indicator current. The allowed values are
+ 2500, 5000, 7500 and 1.
+
+Optional properties of the "indicator" child node
+=
+
+label : The label of the indicator LED.
+
+
+Example
+===
+
+ as3645a@30 {
+ reg = <0x30>;
+ compatible = "ams,as3645a";
+ flash {
+ flash-timeout-us = <15>;
+ flash-max-microamp = <32>;
+ led-max-microamp = <6>;
+ ams,input-max-microamp = <175>;
+ label = "as3645a:flash";
+ };
+ indicator {
+ led-max-microamp = <1>;
+ label = "as3645a:indicator";
+ };
+ };
