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 v3 of the patch series [v1]. It addresses comments made on [v2].
This series is based on the latest next-20251217 linux-next.
Changes from v2 to v3 :
*) Addressed Andrew Davis's comment by placing PRUETH nodes in a new overlay file
am335x-icev2-prueth-overlay.dtso.
*) Rebased the series on latest linux-next.
Changes from v1 to v2 :
*) Addressed Andrew Lunn's comment on patch 1 of the series.
