From 3d0b2a3a87ce5ae85de46c4241afd52ab8b566fe Mon Sep 17 00:00:00 2001 From: Kishon Vijay Abraham I Date: Wed, 17 Mar 2021 18:45:18 +0530 Subject: PCI: keystone: Let AM65 use the pci_ops defined in pcie-designware-host.c MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Both TI's AM65x (K3) and TI's K2 PCIe driver are implemented in pci-keystone. However Only K2 PCIe driver should use it's own pci_ops for configuration space accesses. But commit 10a797c6e54a ("PCI: dwc: keystone: Use pci_ops for config space accessors") used custom pci_ops for both AM65x and K2. This breaks configuration space access for AM65x platform. Fix it here.
