* pci: tegra: Fix port information parsingSjoerd Simons2015-01-23-3/+2
| | | | | | | | | | | | | commit a62e84d7b1824a202dd incorrectly changed the tegra pci code to the new fdtdec pci helpers. To get the device index of the root port, the "reg" property should be parsed from the dtb (as was previously the case). With this patch i can successfully network boot my jetson tk1 Signed-off-by: Sjoerd Simons <sjoerd.simons@collabora.co.uk> Tested-by: Thierry Reding <treding@nvidia.com> Acked-by: Thierry Reding <treding@nvidia.com>
* fdt: Add several apis to decode pci device nodeBin Meng2015-01-13-1/+2
| | | | | | | | | | | | | | This commit adds several APIs to decode PCI device node according to the Open Firmware PCI bus bindings, including: - fdtdec_get_pci_addr() for encoded pci address - fdtdec_get_pci_vendev() for vendor id and device id - fdtdec_get_pci_bdf() for pci device bdf triplet - fdtdec_get_pci_bar32() for pci device register bar Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org> (Include <pci.h> in fdtdec.h and adjust tegra to fix build error)
* pci: tegra: Add Tegra PCIe driverThierry Reding2014-12-18-0/+1143
Add support for the PCIe controller found on some generations of Tegra. Tegra20 has 2 root ports with a total of 4 lanes, Tegra30 has 3 root ports with a total of 6 lanes and Tegra124 has 2 root ports with a total of 5 lanes. This is based on the Linux kernel driver, originally submitted upstream by Mike Rapoport.
