[v3,0/5] Introduce IEP driver and packet timestamping support

Message

MD Danish Anwar Aug. 9, 2023, 11:49 a.m. UTC

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 v3 of the series [v1]. It addresses comments made on [v2].
This series is based on linux-next(#next-20230807).

Changes from v2 to v3:
*) Addressed Roger's comment and moved IEP1 related changes in patch 5.
*) Addressed Roger's comment and moved icss_iep.c / .h changes from patch 4
   to patch 3.
*) Added support for multiple timestamping in patch 4 as asked by Roger.
*) Addressed Andrew's comment and added comment in case SPEED_10 in
   icssg_config_ipg() API.
*) Kept compatible as "ti,am654-icss-iep" for all TI K3 SoCs

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.
