From 2c3f16d70e32d7b5eb62096097c4343c5409afe3 Mon Sep 17 00:00:00 2001 From: Christian Lamparter Date: Wed, 12 Aug 2020 01:21:13 +0200 Subject: apm821xx: WNDR4700: enumerate PCIe in device-tree This patch adds the pcie-switch and bridge configuration of the WNDR4700. This allows to get rid of the legacy firmware monikers and drop the usbport LED declaration.
