[PATCH 4/7] dt-bindings: clock: xilinx: add description of user monitor interrupt

2024-07-20T12:01:54Z

This Xilinx clocking wizard IP core outputs this interrupt signal to
indicate when one of the four optional user clock inputs is either
stopped, overruns, underruns or glitches.

This functionality was only added from version 6.0 onwards, so restrict
it to particular compatible strings.
