From 688697889c9ceb9d2d8d413d1abcc5fa7edb402b Mon Sep 17 00:00:00 2001 From: Felix Baumann Date: Mon, 20 Feb 2023 03:40:20 +0100 Subject: [PATCH] ramips: correct the PCIe port number for some mt7621 devices MT7621 uses a new PCIe driver in the 5.15+ kernel. Allocating wrong PCIe port will cause the PCIe NIC to not work properly. This commit fixes the wrong port numbers on Netgear R6220, WAC104 and WNDR3700 v5. According to bootlog, MT7612E (5GHz) is connected to pcie0, and MT7603E (2GHz) is connected to pcie2: [2.758986] mt7621-pci 1e140000.pcie: pcie1 no card, disable it (RST & CLK) [2.772862] mt7621-pci 1e140000.pcie: PCIE0 enabled [2.782579] mt7621-pci 1e140000.pcie: PCIE2 enabled ...
