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.
