From 6e5aee08bd2517397c9572243a816664f2ead547 Mon Sep 17 00:00:00 2001 From: Thomas Bogendoerfer Date: Thu, 13 Jun 2024 10:17:09 +0200 Subject: Revert "MIPS: pci: lantiq: restore reset gpio polarity" This reverts commit 277a0363120276645ae598d8d5fea7265e076ae9. While fixing old boards with broken DTs, this change will break newer ones with correct gpio polarity annotation.
