LEDs connected to tlc59116 or tlc59108
Required properties
- compatible: should be "ti,tlc59116" or "ti,tlc59108"
- #address-cells: must be 1
- #size-cells: must be 0
- reg: typically 0x68
Each led is represented as a sub-node of the ti,tlc59116.
See Documentation/devicetree/bindings/leds/common.txt
LED sub-node properties:
- reg: number of LED line, 0 to 15 or 0 to 7
- label: (optional) name of LED
- linux,default-trigger : (optional)
Optional properties:
- gpio-controller: Marks the device node as a GPIO controller.
- If present, all the led outputs are registered as gpio outputs, but
the gpio outputs configured as leds are reserved by the driver itself
- #gpio-cells: Should be two.
- first cell is the pin number
- second cell is used for standard gpio bitfield specifiers [1]
- ngpios: Number of gpio outputs added
- Should be <= number of leds lines on the chip, if present.
The most other gpio related devicetree bindings - like gpio-hog - apply
to the tlc591xx node if the gpio output functionality is enabled [1].

#address-cells = <1>;
#size-cells = <0>;
