+Juniper I2CS LED driver.
+
+This is present in Juniper platforms that use a I2CS Slave FPGA.
+
+Required properties:
+ - compatible: must be "jnx,leds-i2cs"
s/compatible:/compatible :/
Also treat the description as a regular sentence, i.e. begin it
with a capital letter and put a dot at the end.
+ - #address-cells : must be 1.
+ - #size-cells : must be 0.
s/must/Must/
+Each led is represented as a sub-node of the jnx,leds-i2cs device.
+
+LED sub-node properties:
+- label : (optional) see Documentation/devicetree/bindings/leds/common.txt
+- reg : number of LED
+- linux,default-trigger : (optional)
+ see Documentation/devicetree/bindings/leds/common.txt
Driver uses also "hw-blink" property. Please document it here, but
add also a prefix:
jnx,hw-blink
Also "jnx" entry should be added to
Documentation/devicetree/bindings/vendor-prefixes.txt.
+Example:
+
+leds_fpc0: leds-jnx-i2cs {
+ compatible = "jnx,leds-i2cs";
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ fpc0-fail {
+ reg = <1>;
It would be good to provide also an example of "label"
property to suggest LED class device name according to
the LED class device naming convention.
See Documentation/leds/leds-class.txt for details.
+ linux,default-trigger = "fpc0-fail";
+ };
+
+ fpc0-ok {
+ reg = <2>;
+ linux,default-trigger = "fpc0-ok";
+ };
+};
