      1* NXP - pca955x LED driver
      2
      3The PCA955x family of chips are I2C LED blinkers whose pins not used
      4to control LEDs can be used as general purpose I/Os. The GPIO pins can
      5be input or output, and output pins can also be pulse-width controlled.
      6
      7Required properties:
      8- compatible : should be one of :
      9	"nxp,pca9550"
     10	"nxp,pca9551"
     11	"nxp,pca9552"
     12	"ibm,pca9552"
     13	"nxp,pca9553"
     14- #address-cells: must be 1
     15- #size-cells: must be 0
     16- reg: I2C slave address. depends on the model.
     17
     18Optional properties:
     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
     22
     23LED sub-node properties:
     24- reg : number of LED line.
     25		from 0 to  1 for the pca9550
     26		from 0 to  7 for the pca9551
     27		from 0 to 15 for the pca9552
     28		from 0 to  3 for the pca9553
     29- type: (optional) either
     30	PCA955X_TYPE_NONE
     31	PCA955X_TYPE_LED
     32	PCA955X_TYPE_GPIO
     33	see dt-bindings/leds/leds-pca955x.h (default to LED)
     34- label : (optional)
     35	see Documentation/devicetree/bindings/leds/common.txt
     36- linux,default-trigger : (optional)
     37	see Documentation/devicetree/bindings/leds/common.txt
