-* Kinetic Technologies - KTD2692 Flash LED Driver
-
-KTD2692 is the ideal power solution for high-power flash LEDs.
-It uses ExpressWire single-wire programming for maximum flexibility.
-
-The ExpressWire interface through CTRL pin can control LED on/off and
-enable/disable the IC, Movie(max 1/3 of Flash current) / Flash mode current,
-Flash timeout, LVP(low voltage protection).
-
-Also, When the AUX pin is pulled high while CTRL pin is high,
-LED current will be ramped up to the flash-mode current level.
-
-Required properties:
-- compatible : Should be "kinetic,ktd2692".
-- ctrl-gpios : Specifier of the GPIO connected to CTRL pin.
-- aux-gpios : Specifier of the GPIO connected to AUX pin.
-
-Optional properties:
-- vin-supply : "vin" LED supply (2.7V to 5.5V).
- See Documentation/devicetree/bindings/regulator/regulator.txt
-
-A discrete LED element connected to the device must be represented by a child
-node - See Documentation/devicetree/bindings/leds/common.txt
-
-Required properties for flash LED child nodes:
- See Documentation/devicetree/bindings/leds/common.txt
-- led-max-microamp : Minimum Threshold for Timer protection
- is defined internally (Maximum 300mA).
-- flash-max-microamp : Flash LED maximum current
- Formula : I(mA) = 15000 / Rset.
-- flash-max-timeout-us : Flash LED maximum timeout.
-
-Optional properties for flash LED child nodes:
-- label : See Documentation/devicetree/bindings/leds/common.txt
-
-Example:
-
-ktd2692 {
- compatible = "kinetic,ktd2692";
- ctrl-gpios = <&gpc0 1 0>;
- aux-gpios = <&gpc0 2 0>;
- vin-supply = <&vbat>;
-
- flash-led {
- label = "ktd2692-flash";
- led-max-microamp = <300000>;
- flash-max-microamp = <1500000>;
- flash-max-timeout-us = <1835000>;
- };
