This series introduces Industrial Ethernet Peripheral (IEP) driver to support timestamping of ethernet packets and thus support PTP and PPS for PRU ICSSG ethernet ports. This series also adds 10M full duplex support for ICSSG ethernet driver. There are two IEP instances. IEP0 is used for packet timestamping while IEP1 is used for 10M full duplex support. This is v2 of the series [v1]. It addresses comments made on [v1]. This series is based on linux-next(#next-20230807). Changes from v1 to v2: *) Addressed Simon's comment to fix reverse xmas tree declaration. Some APIs in patch 3 and 4 were not following reverse xmas tree variable declaration. Fixed it in this version. *) Addressed Conor's comments and removed unsupported SoCs from compatible comment in patch 1. *) Addded patch 2 which was not part of v1. Patch 2, adds IEP node to dt bindings for ICSSG.
