From f953a1a4bfba2fa70c12bb80938aa66481a673b6 Mon Sep 17 00:00:00 2001 From: Alban Bedel Date: Sat, 30 Apr 2022 10:42:33 +0200 Subject: [PATCH] ramips: zbt-wg2626: Add the reset gpio for PCIe port 1 The 2.4GHz interface doesn't come up properly with the log showing: mt7621-pci 1e140000.pcie: pcie1 no card, disable it (RST & CLK) As seen on other MT7621 boards this is caused by a missing reset GPIO. The MT7621 dtsi set GPIO 19 as PCIe reset GPIO, which on this board reset the 5GHz interface on port 0. Add GPIO 8 to the PCIe reset GPIO list to also reset the 2.4GHz interface on port 1.
