+description: |
+ The NXP PCA963x are I2C-controlled LED drivers optimized for
+ Red/Green/Blue/Amber (RGBA) color mixing applications. Each LED is
+ individually controllable and has its own PWM controller.
+
+ Datasheets are available at

-LEDs connected to pca9632, pca9633 or pca9634

-Required properties:
-- compatible : should be : "nxp,pca9632", "nxp,pca9633", "nxp,pca9634" or "nxp,pca9635"
-
-Optional properties:
-- nxp,totem-pole : use totem pole (push-pull) instead of open-drain (pca9632 defaults
- to open-drain, newer chips to totem pole)
-- nxp,hw-blink : use hardware blinking instead of software blinking
-- nxp,period-scale : In some configurations, the chip blinks faster than expected.
- This parameter provides a scaling ratio (fixed point, decimal divided

-- nxp,inverted-out: invert the polarity of the generated PWM
-
-Each led is represented as a sub-node of the nxp,pca963x device.
-
-LED sub-node properties:
-- label : (optional) see Documentation/devicetree/bindings/leds/common.txt
-- reg : number of LED line (could be from 0 to 3 in pca9632 or pca9633,
- 0 to 7 in pca9634, or 0 to 15 in pca9635)

Convert the pca963x DT bindings to YAML schema. The existing properties are kept without modification, but the example is adapted to the latest common bindings for LEDs.
