[PATCH v5 0/3] Add support for ICSSM Ethernet on AM57x, AM437x, and AM335x

[Parvathi Pudi <parvathi@couthit.com>]

Hi,

This series adds support for ICSSM Ethernet on Texas Instruments AM57x,
AM437x and AM335x platforms.

The AM57x and AM437x IDKs support two PRU-ICSS instances, each consisting
of two PRU cores, with each PRU-ICSS instance capable of handling two
Ethernet ports. For the AM57x platforms, the PRU-ICSS2 node has been added
to the am57xx-idk-common.dtsi, while for the AM437x platform, the PRU-ICSS1
node has been added to the am437x-idk-evm.dts.

The AM335x ICE features a single PRU-ICSS instance. A new device tree overlay
source file, am335x-icev2-prueth-overlay.dtso, has been introduced to define the
PRU-ICSS node for the AM335x platform.

This is v5 of the patch series [v1].  It addresses comments made on [v4].
This series is based on the latest next-20260306 linux-next.

Changes from v4 to v5 :
