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 v6 of the patch series [v1]. It addresses comments made on [v5]. This series is based on the latest next-20260401 linux-next. Changes from v5 to v6 : *) Addressed Kevin Hilman, Krzysztof and Andrew lunn comments on patch 3 of the series. *) Fixed an issue with overlaying "output-low" property in "mux-mii-hog" sub-node under "gpio3" node. *) Rebased the series on latest linux-next. Changes from v4 to v5 : *) Addressed Andrew Davis's comments on patch 2 of the series. *) Addressed Andrew Lunn and Nikolaus Schaller comments on patch 2 of the series. *) Rebased the series on latest linux-next. Changes from v3 to v4 : *) No code changes were made, only the version was updated. *) Rebased the series on latest 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. *) Addressed MD Danish Anwar comment on patch 1 of the series. *) Rebased the series on latest linux-next.
