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 v5 of the series [v1]. This addresses comments made on v4.
Changes from v4 to v5:
*) Modified commit message of patch 2/4 as asked by Vignesh.
*) Dropped patch 4/4 ("Enable TI_ICSSG_PRUETH") as it was having build
warning.
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.

2.34.1
The ICSSG IP on AM65x SoCs have two Industrial Ethernet Peripherals (IEPs)
to manage/generate Industrial Ethernet functions such as time stamping.
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.

2.34.1
ICSSG2 provides dual Gigabit Ethernet support.
Add ICSSG2 ethernet node to an overlay k3-am654-icssg2.dtso
Rename the existing k3-am654-base-board.dts to k3-am654-common-board.dts
This represents basic board where ICSSG/PRUs can be used for general
purpose. k3-am654-base-board.dtb is now made of common-board and ICSSG2
specific overlay which enables ICSSG2 dual Ethernet ports available on
base board.

2.34.1
The IDK application board has 4 Gigabit Ethernet ports.
This patch adds support for the 4 Gigabit Ethernet ports
which are provided by ICSSG0 and ICSSG1.
The IEP0 SYNC_OUT0 pins are used for PPS out on the IDK card.
