From a58dfba20168dae18650ad70f47af99be55b1c45 Mon Sep 17 00:00:00 2001 From: "Dr. David Alan Gilbert" Date: Tue, 30 Jul 2019 10:37:18 +0100 Subject: pcie_root_port: Allow ACS to be disabled ACS was added in 4.0 unconditionally, this breaks migration compatibility. Allow ACS to be disabled by adding a property that's checked by pcie_root_port. Unfortunately pcie-root-port doesn't have any instance data, so there's no where for that flag to live, so stuff it into PCIESlot.
