Editing: leds-ktd2692.txt
* 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>; }; };
