1 * NXP - pca955x LED driver
4 to control LEDs can be used as general purpose I/Os. The GPIO pins can
5 be input or output, and output pins can also be pulse-width controlled.
8 - compatible : should be one of :
14 - #address-cells: must be 1
15 - #size-cells: must be 0
16 - reg: I2C slave address. depends on the model.
19 - gpio-controller: allows pins to be used as GPIOs.
20 - #gpio-cells: must be 2.
21 - gpio-line-names: define the names of the GPIO lines
23 LED sub-node properties:
24 - reg : number of LED line.
29 - type: (optional) either
33 see dt-bindings/leds/leds-pca955x.h (default to LED)
