commit 5a938ed9481b0c06cb97aec45e722a80568256fd upstream. commit23284ad677("PCI: keystone: Add support for PCIe EP in AM654x Platforms") introduced configuring "enum dw_pcie_device_mode" as part of device data ("struct ks_pcie_of_data"). However it failed to set the mode for "ti,keystone-pcie" compatible. Since the mode defaults to "DW_PCIE_UNKNOWN_TYPE", the following error message is displayed for the v3.65a controller: "INVALID device type 0" Despite the driver probing successfully, the controller may not be functional in the Root Complex mode of operation. So, set the mode as Root Complex for "ti,keystone-pcie" compatible to fix this.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
