* NXP - pca955x LED driver
|
||||
|
||||
The PCA955x family of chips are I2C LED blinkers whose pins not used
|
||||
to control LEDs can be used as general purpose I/Os. The GPIO pins can
|
||||
be input or output, and output pins can also be pulse-width controlled.
|
||||
|
||||
Required properties:
|
||||
- compatible : should be one of :
|
||||
"nxp,pca9550"
|
||||
"nxp,pca9551"
|
||||
"nxp,pca9552"
|
||||
"ibm,pca9552"
|
||||
"nxp,pca9553"
|
||||
- #address-cells: must be 1
|
||||
- #size-cells: must be 0
|
||||
- reg: I2C slave address. depends on the model.
|
||||
|
||||
Optional properties:
|
||||
- gpio-controller: allows pins to be used as GPIOs.
|
||||
- #gpio-cells: must be 2.
|
||||
- gpio-line-names: define the names of the GPIO lines
|
||||
|
||||
LED sub-node properties:
|
||||
- reg : number of LED line.
|
||||
from 0 to 1 for the pca9550
|
||||
from 0 to 7 for the pca9551
|
||||
from 0 to 15 for the pca9552
|
||||
from 0 to 3 for the pca9553
|
||||
- type: (optional) either
|
||||
PCA955X_TYPE_NONE
|
||||
PCA955X_TYPE_LED
|
||||
PCA955X_TYPE_GPIO
|
||||
see dt-bindings/leds/leds-pca955x.h (default to LED)
|
||||
- label : (optional)
|
||||
see Documentation/devicetree/bindings/leds/common.txt
|
||||
- linux,default-trigger : (optional)
|
||||
see Documentation/devicetree/bindings/leds/common.txt
