From mboxrd@z Thu Jan 1 00:00:00 1970 From: mike@compulab.co.il (Mike Rapoport) Date: Mon, 27 Sep 2010 11:26:31 +0200 Subject: [PATCH v3 0/3] [ARM] tegra: PCI Express support Message-ID: To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org These patches enable PCI Express support on Tegra2. The implementation is based on original NVidia code from (1), but it is heavily reworked to avoid custom PCI enumeration and make the code more Linux friendly. This implementation assumes that the PCIe subsystem is fully powered and ungated by the bootloader. [1] git://nv-tegra.nvidia.com/linux-2.6.git v3 changes: * Fix spelling: s/_OFSET/_OFFSET/ * Make Harmony PCIe initialization multi-platform friendly v2 changes: * Update PCIe clocks implementation as per Colin and Gary suggestions * Update I/O space access as suggested by Arnd and Russell. * Remove debug leftovers and unify error reporting The following changes since commit b30a3f6257ed2105259b404d419b4964e363928c: Linus Torvalds (1): Linux 2.6.36-rc5 Mike Rapoport (3): [ARM] tegra: add PCI Express clocks [ARM] tegra: add PCI Express support [ARM] tegra: harmony: enable PCI Express arch/arm/mach-tegra/Kconfig | 4 + arch/arm/mach-tegra/Makefile | 2 + arch/arm/mach-tegra/board-harmony-pcie.c | 57 ++ arch/arm/mach-tegra/board.h | 1 + arch/arm/mach-tegra/include/mach/hardware.h | 4 + arch/arm/mach-tegra/include/mach/io.h | 12 +- arch/arm/mach-tegra/pcie.c | 915 +++++++++++++++++++++++++++ arch/arm/mach-tegra/tegra2_clocks.c | 46 ++ 8 files changed, 1040 insertions(+), 1 deletions(-) create mode 100644 arch/arm/mach-tegra/board-harmony-pcie.c create mode 100644 arch/arm/mach-tegra/pcie.c
