From d4e8c8ad5d14ad51ed8813442d81c43019fd669d Mon Sep 17 00:00:00 2001 From: Suman Anna Date: Thu, 15 Feb 2024 16:00:34 +0530 Subject: [PATCH] arm64: dts: ti: k3-am64-main: Add ICSSG IEP nodes 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.
