Hi Santosh,
The following series adds the base support for the ICSSG IP on AM64x SoCs.
Patches are on top of v5.13-rc1 + minor fix that Jan had posted [1].
The ICSSG IP on AM64x is a minor revised version that looks almost same as
the version used on J721E. There is no SGMII support on AM64x SoCs, but
otherwise they have the same 2 PRUs, 2 RTUS and 2 Tx_PRUs just like J721E
and AM65x SR2.0 SoCs.
The CFG sub-module is the only sub-module that has a different revision
version w.r.t J721E. J721E and AM65x differed in CFG, ECC Aggregator,
RAT Slices. ECAP, INTC, MDIO and UART0 are all identical. There are no
revision registers on IEP0/IEP1, MII_RT, MII_G_RT, PROTECT or TASK Manager
modules, and these look to be identical from a quick register comparision
from TRM. There are no SGMII registers at all. IEP, MII_RT and MII_G_RT
are also syscon nodes, so any differences would have to be dealt
within the client drivers.
regards,
Suman

The K3 AM64x SoCs also have the Gigabit Ethernet capable PRU-ICSS IP
that is present on existing K3 AM65x and J721E SoCs (ICSSG). The IP
is similar to the ones used on K3 J721E or AM65x SR2.0 SoCs.
Update the PRUSS bindings for these ICSSG instances.

The K3 AM64x family of SoCs have a similar version of the PRU-ICSS (ICSSG)
processor subsystem present on K3 J721E and K3 AM65x SR2.0 SoCs. These SoCs
contain typically two ICSSG instances named ICSSG0 and ICSSG1. The two
ICSSGs are identical to each other for the most part with minor SoC
integration differences and capabilities. SGMII mode is not supported at
all on these SoCs (unlike specific instances on AM65x, J721E). The ICSSG1
also has limited pins connected on some sub-modules compared to ICSSG0.
There is no change in the Interrupt Controller w.r.t either of AM65x or
J721E SoCs. All other integration aspects are also very similar to the
existing SoCs.
The existing pruss platform driver has been updated to support these
similar ICSSG instances through a new AM64x specific compatible.
