From cfb56b481131f601d5a587a8d89a752b1fd54d0b Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Sun, 10 May 2015 11:47:09 +0000 Subject: ipq806x: add pcie support to ipq806x based platforms This change adds PCIe support to IPQ806x based platforms. The driver is actually cherry-picked from the following LKML thread: *https://lwn.net/Articles/643086/ (patches 110-111) We also add here an additional fix to support multiple PCI controllers on the same platform (patch 112), and to patch the ap148 & dbs149 DTS files (patch 113).
