Subject[PATCH 4.16 024/110] x86/amd_nb: Add support for Raven Ridge CPUs
Date
4.16-stable review patch.  If anyone has any objections, please let me know.

From: Guenter Roeck <linux@roeck-us.net>

commit f9bc6b2dd9cf025f827f471769e1d88b527bfb91 upstream.

Add Raven Ridge root bridge and data fabric PCI IDs.
This is required for amd_pci_dev_to_node_id() and amd_smn_read().
