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
