[PATCH v6 2/3] dt-bindings: pci-imx6: Add one more external reference clock

[Bjorn Helgaas]

Update subject line similar to patch 1/3?

Also, I notice most binding commits include "PCI:", e.g.,

  dt-bindings: PCI: brcm,stb-pcie: ...
  dt-bindings: PCI: qcom: ...
  dt-bindings: PCI: altera ...

Not sure what "onhalf" means.  Maybe it means something like this?

  The "extref" clock refers to a reference clock from an external
  crystal oscillator.

Same issue in patch 3/3.
