Subject: [PATCH v4 1/3] arm64: dts: ti: k3-am64-main: Add ICSSG IEP nodes

From: Suman Anna <[email protected]>

The ICSSG IP on AM64x SoCs have two Industrial Ethernet Peripherals (IEPs)
to manage/generate Industrial Ethernet functions such as time stamping.
Each IEP sub-module is sourced from an internal clock mux that can be
derived from either of the IP instance's ICSSG_IEP_GCLK or from another
internal ICSSG CORE_CLK mux. Add both the IEP nodes for both the ICSSG
instances. The IEP clock is currently configured to be derived
indirectly from the ICSSG_ICLK running at 250 MHz.
