[PATCH 0/4] arm64: dts: renesas: Fix PHY C22 compatible strings

From: Marek Vasut

Date: Fri Mar 13 2026 - 12:42:08 EST


Realtek RTL8211E/RTL8211F and Microchip KSZ9131 PHY schemas
indicate that compatible string "ethernet-phy-id001c.c91[56]"
and "ethernet-phy-id0022.1640" must not be followed by any
other compatible string. Drop "ethernet-phy-ieee802.3-c22"
to match the schemas.

The KSZ9131 schema does not document "txdv-skew-psec" property.
Fix what is likely a copy-paste error from the "rxdv-skew-psec"
property, use "txen-skew-psec" property instead.

This is compile-tested and schema validated only. I have discussed
this with Biju and they could perform tests on real hardware to
assure no breakage. Please wait for their TB before applying.
