+description:
+ The NXP PCA9952/PCA9955B are programmable LED controllers connected via I2C
+ that can drive 16 separate lines. Each of them can be individually switched
+ on and off, and brightness can be controlled via individual PWM.
+
+ Datasheets are available at
+ https://www.nxp.com/docs/en/data-sheet/PCA9952_PCA9955.pdf

The PCA995x chips are I2C controlled LED drivers. Each chip has up to 16 outputs, each one with an individual 8-bit resolution PWM for brightness control. Add binding document.
