1LEDs connected to pca9632, pca9633 or pca9634 2 3Required properties: 4- compatible : should be : "nxp,pca9632", "nxp,pca9633", "nxp,pca9634" or "nxp,pca9635" 5 6Optional properties: 7- nxp,totem-pole : use totem pole (push-pull) instead of open-drain (pca9632 defaults 8 to open-drain, newer chips to totem pole) 9- nxp,hw-blink : use hardware blinking instead of software blinking 10- nxp,period-scale : In some configurations, the chip blinks faster than expected. 11 This parameter provides a scaling ratio (fixed point, decimal divided 12 by 1000) to compensate, e.g. 1300=1.3x and 750=0.75x. 13- nxp,inverted-out: invert the polarity of the generated PWM 14 15Each led is represented as a sub-node of the nxp,pca963x device. 16 17LED sub-node properties: 18- label : (optional) see Documentation/devicetree/bindings/leds/common.txt 19- reg : number of LED line (could be from 0 to 3 in pca9632 or pca9633, 20 0 to 7 in pca9634, or 0 to 15 in pca9635) 21- linux,default-trigger : (optional) 22 see Documentation/devicetree/bindings/leds/common.txt 23 24Examples: 25 26pca9632: pca9632 { 27 compatible = "nxp,pca9632"; 28 #address-cells = <1>; 29 #size-cells = <0>; 30 reg = <0x62>; 31 32 red@0 { 33 label = "red"; 34 reg = <0>; 35 linux,default-trigger = "none"; 36 }; 37 green@1 { 38 label = "green"; 39 reg = <1>; 40 linux,default-trigger = "none"; 41 }; 42 blue@2 { 43 label = "blue"; 44 reg = <2>; 45 linux,default-trigger = "none"; 46 }; 47 unused@3 { 48 label = "unused"; 49 reg = <3>; 50 linux,default-trigger = "none"; 51 }; 52};
