This adds documentation of device tree bindings for the mxc rtc.
Perhaps don't further propagate the long dead MXC name and use "imx" everywhere. What the Linux driver is called doesn't matter here.

What about newer versions with the secure functionality. IIRC, that was in MX31 and later.

+- interrupts: IRQ line for the RTC.
+- clocks: should contain two entries:
