From 2f663cab46dd20a3372d206d02876326012904bf Mon Sep 17 00:00:00 2001 From: Daniel Golle Date: Mon, 27 Mar 2023 16:02:44 +0100 Subject: [PATCH] generic: replace mtk_sgmii patches with versions accepted upstream Replace patches for MediaTek Ethernet driver SGMII/SerDes unit with their corresponding upstream patches. Not all of the patches in our tree went upstream as-is, some are slightly different implementations, and they require the phylink_pcs helpers now made available.
