1LEDs connected to is31fl319x LED controller chip
2
3Required properties:
4- compatible : Should be any of
5	"issi,is31fl3190"
6	"issi,is31fl3191"
7	"issi,is31fl3193"
8	"issi,is31fl3196"
9	"issi,is31fl3199"
10	"si-en,sn3199".
11- #address-cells: Must be 1.
12- #size-cells: Must be 0.
13- reg: 0x64, 0x65, 0x66, or 0x67.
14
15Optional properties:
16- audio-gain-db : audio gain selection for external analog modulation input.
17	Valid values: 0 - 21, step by 3 (rounded down)
18	Default: 0
19- shutdown-gpios : Specifier of the GPIO connected to SDB pin of the chip.

21Each led is represented as a sub-node of the issi,is31fl319x device.
22There can be less leds subnodes than the chip can support but not more.
23
24Required led sub-node properties:
25- reg : number of LED line
26	Valid values: 1 - number of leds supported by the chip variant.
27
28Optional led sub-node properties:
29- label : see Documentation/devicetree/bindings/leds/common.txt.
30- linux,default-trigger :
31	see Documentation/devicetree/bindings/leds/common.txt.
32- led-max-microamp : (optional)
33	Valid values: 5000 - 40000, step by 5000 (rounded down)
34	Default: 20000 (20 mA)
35	Note: a driver will take the lowest of all led limits since the
36	chip has a single global setting. The lowest value will be chosen
37	due to the PWM specificity, where lower brightness is achieved
38	by reducing the dury-cycle of pulses and not the current, which
39	will always have its peak value equal to led-max-microamp.
