Detailed Description

INPUTMUX connection cookies for the NXP BASIC FREQME (fmeas) inputs.

These mirror the kINPUTMUX_<source>ToFreqmeas enumerators in each SoC's fsl_inputmux_connections.h.

A cookie encodes the FMEASURE destination mux id (0x700) shifted by the INPUTMUX PMUX_SHIFT (20) OR'ed with the per-source selector value.

In the devicetree, cookies are used as the "connection" specifier in "mux-states = <&inputmux channel connection>" inside "reference-sources" and "target-sources" child nodes. The channel cell selects the FMEASURE_CH_SEL slot (0 = reference, 1 = target); the same connection cookie is valid for either channel.

The connection cookie is also the runtime clock_monitor_set_source() selector for both reference and target sources.
