+Subject: [PATCH] ARM: dts: stm32: lxa-mc1: Fix kernel warning about PHY delays
+
+The KSZ9031 PHY skew timings for rxc/txc, originally set to achieve
+the desired phase shift between clock- and data-signal, now trigger a
+kernel warning when used in rgmii-id mode:
+
+ *-skew-ps values should be used only with phy-mode = "rgmii"
+
+This is because commit bcf3440c6dd7 ("net: phy: micrel: add phy-mode
+support for the KSZ9031 PHY") now configures own timings when
+phy-mode = "rgmii-id". Device trees wanting to set their own delays
+should use phy-mode "rgmii" instead as the warning prescribes.
+
+The "standard" timings now used with "rgmii-id" work fine on this
+board, so drop the explicit timings in the device tree and thereby
+silence the warning.
+
+Fixes: 666b5ca85cd3 ("ARM: dts: stm32: add STM32MP1-based Linux Automation MC-1 board")
