+Qualcomm PM8058 LED driver
+
+The Qualcomm PM8058 is a multi-functional device which contain
+a LED driver block for up to six LEDs: three normal LEDs, two
+"flash" LEDs and one "keypad backlight" LED. The names are
+quoted because sometimes these LED drivers are used for wildly
+different things than flash or keypad backlight: their names
+are more of a suggestion than a hard-wired usecase.
+
+Hardware-wise the different LEDs support slightly different
+output currents. The "flash" LEDs do not need to charge nor
+do they support external triggers. They are just powerful LED
+drivers.
+
+The LEDs appear as children to the PM8058 device, with the
+proper compatible string. For the PM8058 bindings see:
+mfd/qcom-pm8xxx.txt.
+
+Each LED is represented as a sub-node of the syscon device. Each
+node's name represents the name of the corresponding LED.
+
+LED sub-node properties:
+
+Required properties:
+- compatible: on of
+ "qcom,pm8058-led" (for the normal LEDs at 0x131, 0x132 and 0x133)
+ "qcom,pm8058-keypad-led" (for the "keypad" LED at 0x48)
+ "qcom,pm8058-flash-led" (for the "flash" LEDs at 0x49 and 0xFB)
+
+Optional properties:
+- label: descriptive name for the LED see common.txt
Please use just "see Documentation/devicetree/bindings/leds/common.txt"
as a description of this property.
+- default-state: The initial state of the LED see common.txt
Please use just "Documentation/devicetree/bindings/leds/leds-gpio.txt"
as a description of this property.
+- linux,default-trigger: Linux trigger, see common.txt
Please use just "see Documentation/devicetree/bindings/leds/common.txt"
as a description of this property.
+
+Example:
+
+qcom,ssbi@500000 {
+ pmicintc: pmic@0 {
+ compatible = "qcom,pm8058";
+ led@48 {
+ compatible = "qcom,pm8058-keypad-led";
+ reg = <0x48>;
+ label = "keypad";
+ default-state = "off";
+ };
+ led@131 {
+ compatible = "qcom,pm8058-led";
+ reg = <0x131>;
+ label = "pm8058:red";
+ default-state = "off";
+ };
+ led@132 {
+ compatible = "qcom,pm8058-led";
+ reg = <0x132>;
+ label = "pm8058:yellow";
+ default-state = "off";
+ linux,default-trigger = "mmc0";
+ };
+ led@133 {
+ compatible = "qcom,pm8058-led";
+ reg = <0x133>;
+ label = "pm8058:green";
+ default-state = "on";
+ linux,default-trigger = "heartbeat";
+ };
+ };
+};
