+  The clock consumer should specify the desired clock by having the clock
+  ID in its "clocks" phandle cell. See include/dt-bindings/clock/imxrt*-clock.h
+  for the full list of i.MXRT clock IDs.

Don't need oneOf for a single entry.

You have to define the name.

Not relevant to the example.

Drop unused labels.

Probably should be: "fsl,imxrt1050-gpt", "fsl,imx31-gpt"

Unless there's same features/quirks as the MX53 version?
