From bd0c7718ae1877e2e4eeb903096e905754d5df78 Mon Sep 17 00:00:00 2001 From: Gatien Chevallier Date: Mon, 1 Sep 2025 11:16:29 +0200 Subject: [PATCH] ARM: dts: stm32: add missing PTP reference clocks on stm32mp13x SoCs 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.
