+LEDs connected to is31fl319x LED controller chip
+
+Required properties:
+- compatible : Should be any of
+ "issi,is31fl3190"
+ "issi,is31fl3191"
+ "issi,is31fl3193"
+ "issi,is31fl3196"
+ "issi,is31fl3199"
+ "si-en,sn3199".
+- #address-cells: Must be 1.
+- #size-cells: Must be 0.
+- reg: 0x64, 0x65, 0x66, 0x67.
+
+Optional properties:
+- led-max-microamp : See Documentation/devicetree/bindings/leds/common.txt.
+ Valid values: 5000 - 40000, step by 5000 (rounded down)
+ Default: 20000 (20 mA)
+- audio-gain-db : audio gain selection for external analog modulation input.
+ Valid values: 0 - 21, step by 3 (rounded down)
+ Default: 0
+
+Each led is represented as a sub-node of the issi,is31fl319x device.
+There can be less leds subnodes than the chip can support but not more.
+
+LED sub-node properties:
+- label : (optional) see Documentation/devicetree/bindings/leds/common.txt.
+- reg : number of LED line
+ Valid values: 1 - number of leds supported by the chip variant.
+- linux,default-trigger : (optional)
+ see Documentation/devicetree/bindings/leds/common.txt.
+
+Examples:
+
+fancy_leds: leds@65 {
+ compatible = "issi,is31fl3196";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <0x65>;
+
+ red_aux: led@1 {
+ label = "red:aux";
+ reg = <1>;
+ };
+
+ green_power: led@5 {
+ label = "green:power";
+ reg = <5>;
+ linux,default-trigger = "default-on";
+ };
