9*c66ec88fSEmmanuel Vadot- compatible : Should be "ibm,opal-sensor-group"
10*c66ec88fSEmmanuel Vadot
11*c66ec88fSEmmanuel VadotEach child node contains below properties:
12*c66ec88fSEmmanuel Vadot
13*c66ec88fSEmmanuel Vadot- type : String to indicate the type of sensor-group
14*c66ec88fSEmmanuel Vadot
15*c66ec88fSEmmanuel Vadot- sensor-group-id: Abstract unique identifier provided by firmware of
16*c66ec88fSEmmanuel Vadot		   type <u32> which is used for sensor-group
17*c66ec88fSEmmanuel Vadot		   operations like clearing the min/max history of all
18*c66ec88fSEmmanuel Vadot		   sensors belonging to the group.
19*c66ec88fSEmmanuel Vadot
