-LEDs connected to is31fl319x LED controller chip

-- compatible : Should be any of

- "issi,is31fl3191"
- "issi,is31fl3193"
- "issi,is31fl3196"

-- #address-cells: Must be 1.
-- #size-cells: Must be 0.
-- reg: 0x64, 0x65, 0x66, or 0x67.
-
-Optional properties:
-- audio-gain-db : audio gain selection for external analog modulation input.
- Valid values: 0 - 21, step by 3 (rounded down)
- Default: 0
-- shutdown-gpios : Specifier of the GPIO connected to SDB pin of the chip.
-
-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.
-
-Required led sub-node properties:
-- reg : number of LED line
- Valid values: 1 - number of leds supported by the chip variant.
-
-Optional led sub-node properties:
-- label : see Documentation/devicetree/bindings/leds/common.txt.
-- linux,default-trigger :
- see Documentation/devicetree/bindings/leds/common.txt.
-- led-max-microamp : (optional)
- Valid values: 5000 - 40000, step by 5000 (rounded down)
- Default: 20000 (20 mA)
- Note: a driver will take the lowest of all led limits since the
- chip has a single global setting. The lowest value will be chosen
- due to the PWM specificity, where lower brightness is achieved
- by reducing the dury-cycle of pulses and not the current, which
- will always have its peak value equal to led-max-microamp.
