13*833e5d42SEmmanuel Vadot  The DPLL pin is either a physical input or output pin that is provided
14*833e5d42SEmmanuel Vadot  by a DPLL( Digital Phase-Locked Loop) device. The pin is identified by
15*833e5d42SEmmanuel Vadot  its physical order number that is stored in reg property and can have
16*833e5d42SEmmanuel Vadot  an additional set of properties like supported (allowed) frequencies,
17*833e5d42SEmmanuel Vadot  label, type and may support embedded sync.
18*833e5d42SEmmanuel Vadot
19*833e5d42SEmmanuel Vadot  Note that the pin in this context has nothing to do with pinctrl.
