Subject: [PATCH v4 3/5] arm64: dts: ti: k3-am64-main: Add ICSSG IEP nodes
Date: Fri, 02 Feb 2024 17:10:50 +0100	[thread overview]
Message-ID: <20240202-add-am64-som-v4-3-5f8b12af5e71@solid-run.com> (raw)
In-Reply-To: <20240202-add-am64-som-v4-0-5f8b12af5e71@solid-run.com>

From: Suman Anna <s-anna@ti.com>

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.
