From 4f0f36b67564311a4ce4441510ef94848febbab2 Mon Sep 17 00:00:00 2001 From: Sergio Paracuellos Date: Sun, 22 Mar 2020 08:21:28 +0100 Subject: [PATCH] staging: mt7621-pci: avoid to set 'iomem_resource' addresses Setting up kernel resource 'iomem_resource' for PCI with addresses parsed from device tree gots into a conflict within the usb xhci driver: xhci-mtk 1e1c0000.xhci: can't request region for resource [mem 0x1e1c0000-0x1e1c0fff] xhci-mtk: probe of 1e1c0000.xhci failed with error -16 Don't assign it and maintain the default addresses for this resource seems to fix the problem. Checking legacy driver it is being only setting the 'ioport_resource'.
