-LEDs connected to tca6507
-
-Required properties:
-- compatible : should be : "ti,tca6507".
-- #address-cells: must be 1
-- #size-cells: must be 0
-- reg: typically 0x45.
-
-Optional properties:
-- gpio-controller: allows lines to be used as output-only GPIOs.
-- #gpio-cells: if present, must not be 0.
-
-Each led is represented as a sub-node of the ti,tca6507 device.
-
-LED sub-node properties:
-- label : (optional) see Documentation/devicetree/bindings/leds/common.txt
-- reg : number of LED line (could be from 0 to 6)
-- linux,default-trigger : (optional)
- see Documentation/devicetree/bindings/leds/common.txt
-- compatible: either "led" (the default) or "gpio".

-

+description:
+ The TCA6507 is a programmable LED controller connected via I2C that can drive
+ 7 separate lines either by holding them low, or by pulsing them with modulated
+ width.
