+Required properties inside child node. Chile node contains settings for each individual LED.
+Each LED hardware needs a node for itself and a switch node to control brightness.
+For the purpose of turning on/off LED and better regulator control, "led:switch" node
+is introduced. "led:switch" acquires several existing properties from other nodes for
+operational simplification. For backward compatibility purpose, switch node can be optional:
+- label : type of led that will be used, either "flash" or "torch".
+- qcom,led-name : name of the LED. Accepted values are "led:flash_0",
+ "led:flash_1", "led:torch_0", "led:torch_1"
+- qcom,default-led-trigger : trigger for the camera flash and torch. Accepted values are
+ "flash0_trigger", "flash1_trigger", "torch0_trigger", torch1_trigger"
+- qcom,id : enumerated ID for each physical LED. Accepted values are "0",
+ "1", etc..
+- qcom,max-current : maximum current allowed on this LED. Valid values should be
+ integer from 0 to 1000 inclusive, indicating 0 to 1000 mA.
+- qcom,pmic-revid : PMIC revision id source. This property is needed for PMI8996
+ revision check.
+
+Optional properties inside child node:
+- qcom,current : default current intensity for LED. Accepted values should be
+ integer from 0 t 1000 inclusive, indicating 0 to 1000 mA.
+- qcom,duration : Duration for flash LED. When duration time expires, hardware will turn off
+ flash LED. Values should be from 10 ms to 1280 ms with 10 ms incremental
+ step. Not applicable to torch. It is required for LED:SWITCH node to handle
+ LED used as flash.
+- reg<n> : reg<n> (<n> represents number. eg 0,1,2,..) property is to add support for
+ multiple power sources. It includes two properties regulator-name and max-voltage.
+ Required property inside regulator node:
+ - regulator-name : This denotes this node is a regulator node and which
+ regulator to use.
+ Optional property inside regulator node:
+ - max-voltage : This specifies max voltage of regulator. Some switch
+ or boost regulator does not need this property.
