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 v4 of the series [v1]. It addresses comments made on [v3].
This series is based on linux-next(#next-20230809).
Change from v3 to v4:
*) Changed compatible in iep dt bindings. Now each SoC has their own compatible
in the binding with "ti,am654-icss-iep" as a fallback as asked by Conor.
*) Addressed Andew's comments and removed helper APIs icss_iep_readl() /
writel(). Now the settime/gettime APIs directly use readl() / writel().
*) Moved selecting TI_ICSS_IEP in Kconfig from patch 3 to patch 4.
*) Removed forward declaration of icss_iep_of_match in patch 3.
*) Replaced use of of_device_get_match_data() to device_get_match_data() in
patch 3.
*) Removed of_match_ptr() from patch 3 as it is not needed.
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.
