From 7dc54d3b8d9100c65b0860f76342fc9f3b4694d9 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Cl=C3=A9ment=20L=C3=A9ger?= Date: Fri, 24 Jun 2022 16:39:50 +0200 Subject: net: pcs: add Renesas MII converter driver MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add a PCS driver for the MII converter that is present on the Renesas RZ/N1 SoC. This MII converter is reponsible for converting MII to RMII/RGMII or act as a MII pass-trough. Exposing it as a PCS allows to reuse it in both the switch driver and the stmmac driver. Currently, this driver only allows the PCS to be used by the dual Cortex-A7 subsystem since the register locking system is not used.
