Hi All,
This series adds support for ICSSG ethernet on AM65x SR2.0.
This series also enables TI_ICSSG_PRUETH as loadable kernel module.
This series is based on the latest next-20230925 linux-next.
This is the v4 of the series [v1]. This addresses comments made on v3.
Changes from v3 to v4:
*) Added RB tag of Andrew Davis.
*) Added LAKML to the --cc of this series as it was dropped in v3.
Changes from v2 to v3:
*) Changed comment of icssg nodes in device trees from "Dual Ethernet
application node" to "Ethernet node" as asked by Andrew L.
*) Applied k3-am654-idk.dtbo at build time to the k3-am654-base-board.dtb
in order to not have orphan DTBO as asked by Andrew D.
*) Modified k3-am654-gp-evm.dtb to have k3-am654-icssg2.dtbo as well.
Changes from v1 to v2:
*) Moved ICSSG2 nodes from k3-am654-base-board.dts to new overlay file
k3-am654-icssg2.dtso as asked by Andrew.
*) Renamed k3-am654-base-board.dts to k3-am654-common-board.dts
*) Added "Enable TI_ICSSG_PRUETH" patch to this series.

Each IEP sub-module is sourced from an internal clock mux that can be sourced from either of the IP instance's ICSSG_IEP_GCLK or ICSSG_ICLK. Add the IEP nodes for all the ICSSG instances.

This subsystem is provided for the use cases like implementation of custom peripheral interfaces, offloading of tasks from the other processor cores of the SoC, etc. Currently AM654x-EVM uses ICSSG driver.
