From d9d49c9f9ceda24fed317c36ac321f3c4c8e7e06 Mon Sep 17 00:00:00 2001 From: Pratyush Anand Date: Tue, 11 Feb 2014 11:39:26 +0530 Subject: PCI: spear: Add PCIe driver for ST Microelectronics SPEAr13xx ARM based ST Microelectronics's SPEAr1310 and SPEAr1340 SOCs have onchip designware PCIe controller. To make that usable, this patch adds a wrapper driver based on existing designware driver. Adds bindings for this new driver and update MAINTAINERS as well.
