Subject: [PATCHv5 1/4] dt-bindings: wiegand: add Wiegand controller common properties
Wiegand bus is defined by a Wiegand controller node. This node
can contain one or more device nodes for devices attached to
the controller(it is advised to only connect one device as Wiegand
is a point-to-point bus).
Wiegand controller needs to specify several attributes such as
the pulse length in order to function properly. These attributes
are documented here.
