Commit-Message
In contrast to fixed clocks that are described as ungateable, boards sometimes use additional oscillators for things like PCIe reference clocks, that need actual supplies to get enabled and enable-gpios to be toggled for them to work. This adds a binding for such oscillators that are not configurable themself, but need to handle supplies for them to work. In schematics they often can be seen as ---------------- Enable - | 100MHz,3.3V, | - VDD | 3225 | GND - | | - OUT ---------------- or similar. The enable pin might be separate but can also just be tied to the vdd supply, hence it is optional in the binding.
