Subject: [PATCH net-next 0/8] net: enetc: Add i.MX94 ENETC support

i.MX94 NETC has two kinds of ENETCs, one is the same as i.MX95, which
can be used as a standalone network port. The other one is an internal
ENETC, it connects to the CPU port of NETC switch through the pseudo
MAC. Also, i.MX94 have multiple PTP Timers, which is different from
i.MX95. Any PTP Timer can be bound to a specified standalone ENETC by
the IERB ETBCR registers. Currently, this patch only add ENETC support
and Timer support for i.MX94. The switch will be added by a separate
patch set.

---
Note that the DTS patch (patch 8/8) is just for referenece, it will be
removed from this patch set when the dt-bindings patches have been
reviewed. It will be sent for review by another thread in the future.
