Subject: [PATCH net-next v4 3/3] ARM: dts: stm32: add missing PTP reference clocks on stm32mp13x SoCs
Date: Mon, 1 Sep 2025 11:16:29 +0200 [thread overview]
Message-ID: <20250901-relative_flex_pps-v4-3-b874971dfe85@foss.st.com> (raw)
In-Reply-To: <20250901-relative_flex_pps-v4-0-b874971dfe85@foss.st.com>
ETH1/2 miss their PTP reference clock in the SoC device tree. Add them
as the fallback is not correctly handled for PPS generation and it seems
there's no reason to not add them.
