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 source
file, am335x-icev2-prueth.dts, has been introduced to define the PRU-ICSS node
for the AM335x platform.
This is v2 of the patch series [v1]. It addresses comments made on [v1].
This series is based on the latest next-20251103 linux-next.
Changes from v1 to v2 :
*) Addressed Andrew Lunn's comment on patch 1 of the series.
*) Addressed MD Danish Anwar comment on patch 1 of the series.
*) Rebased the series on latest linux-next.
[v1] https://lore.kernel.org/all/20251013125401.1435486-1-parvathi@couthit.com/
Thanks and Regards,
Parvathi.

Davis, Murali Karicheri From: Roger Quadros <rogerq@ti.com> The TI Sitara AM57xx series of devices consists of 2 PRU-ICSS instances (PRU-ICSS1 and PRU-ICSS2). This patch adds the device tree nodes for the PRU-ICSS2 instance to support DUAL-MAC mode of operation. Each PRU-ICSS instance consists of two PRU cores along with various peripherals such as the Interrupt Controller (PRU_INTC), the Industrial Ethernet Peripheral(IEP), the Real Time Media Independent Interface controller (MII_RT), and the Enhanced Capture (eCAP) event module. am57-pruss.dtsi - Adds IEP and eCAP peripheral as child nodes of the PRUSS subsystem node. am57xx-idk-common.dtsi - Adds PRU-ICSS2 instance node along with PRU eth port information and corresponding port configuration. It includes interrupt mapping for packet reception, HW timestamp collection, and PRU Ethernet ports in MII mode. am571x-idk.dts, am572x-idk.dts and am574x-idk.dts - GPIO configuration along with delay configuration for individual PRU Ethernet port.

Maybe that is how we hacked around this in our evil vendor tree back in 2018 but do not take our old hacks and push them upstream as-is.
