From e8b8318de645c04f8600cb5af6f6773a1878ee9d Mon Sep 17 00:00:00 2001 From: Ray Jui Date: Fri, 4 Dec 2015 09:34:58 -0800 Subject: [PATCH 1/5] PCI: iproc: Update iProc PCIe device tree binding Add a new compatible string "brcm,iproc-pcie-paxc", for PAXC-based iProc PCIe root complex. A PAXC-based PCIe root complex is connected to emulated endpoint devices internal to the ASIC.
