1*4882a593SmuzhiyunBindings for Linear Technologies LT3593 LED controller 2*4882a593Smuzhiyun 3*4882a593SmuzhiyunRequired properties: 4*4882a593Smuzhiyun- compatible: Should be "lltc,lt3593". 5*4882a593Smuzhiyun- lltc,ctrl-gpios: A handle to the GPIO that is connected to the 'CTRL' 6*4882a593Smuzhiyun pin of the chip. 7*4882a593Smuzhiyun 8*4882a593SmuzhiyunThe hardware supports only one LED. The properties of this LED are 9*4882a593Smuzhiyunconfigured in a sub-node in the device node. 10*4882a593Smuzhiyun 11*4882a593SmuzhiyunOptional sub-node properties: 12*4882a593Smuzhiyun- function: See Documentation/devicetree/bindings/leds/common.txt 13*4882a593Smuzhiyun- color: See Documentation/devicetree/bindings/leds/common.txt 14*4882a593Smuzhiyun- label: A label for the LED. If none is given, the LED will be 15*4882a593Smuzhiyun named "lt3595::" (deprecated) 16*4882a593Smuzhiyun- linux,default-trigger: The default trigger for the LED. 17*4882a593Smuzhiyun See Documentation/devicetree/bindings/leds/common.txt 18*4882a593Smuzhiyun- default-state: The initial state of the LED. 19*4882a593Smuzhiyun See Documentation/devicetree/bindings/leds/common.txt 20*4882a593Smuzhiyun 21*4882a593SmuzhiyunIf multiple chips of this type are found in a design, each one needs to 22*4882a593Smuzhiyunbe handled by its own device node. 23*4882a593Smuzhiyun 24*4882a593SmuzhiyunExample: 25*4882a593Smuzhiyun 26*4882a593Smuzhiyun#include <dt-bindings/leds/common.h> 27*4882a593Smuzhiyun 28*4882a593Smuzhiyunled-controller { 29*4882a593Smuzhiyun compatible = "lltc,lt3593"; 30*4882a593Smuzhiyun lltc,ctrl-gpios = <&gpio 0 GPIO_ACTIVE_HIGH>; 31*4882a593Smuzhiyun 32*4882a593Smuzhiyun led { 33*4882a593Smuzhiyun function = LED_FUNCTION_BACKLIGHT; 34*4882a593Smuzhiyun color = <LED_COLOR_ID_WHITE>; 35*4882a593Smuzhiyun default-state = "on"; 36*4882a593Smuzhiyun }; 37*4882a593Smuzhiyun}; 38
