From d1523b52bff35ea709141abac87dd701559ef290 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Fri, 9 Aug 2013 16:49:19 +0200 Subject: PCI: tegra: Move PCIe driver to drivers/pci/host Move the PCIe driver from arch/arm/mach-tegra into the drivers/pci/host directory. The motivation is to collect various host controller drivers in the same location in order to facilitate refactoring. The Tegra PCIe driver has been largely rewritten, both in order to turn it into a proper platform driver and to add MSI (based on code by Krishna Kishore ) as well as device tree support.
