* dm: tegra: pci: Convert tegra boards to driver model for PCISimon Glass2015-12-01-322/+155
| | | | | | | | | Adjust the Tegra PCI driver to support driver model and move all boards over at the same time. This can make use of some generic driver model code, such as the range-decoding logic. Signed-off-by: Simon Glass <sjg@chromium.org> Tested-by: Stephen Warren <swarren@nvidia.com>
* pci: tegra: add/enable support for Tegra210Stephen Warren2015-11-12-0/+22
| | | | | | | | | This needs a separate compatible value from Tegra124 since the new HW version has bugs that would prevent a driver for previous HW versions from operating at all. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
* pci: tegra: call tegra_pcie_board_init() earlierStephen Warren2015-11-12-2/+2
| | | | | | | | | | The board PCI setup code may control regulators that are required simply to bring up the PCI controller itself (or PLLs, IOs, ... it uses). Move the call to this function earlier so that all board-provided resources are ready early enough for everything to work.

* pci: tegra: implement PCA enable workaroundStephen Warren2015-11-12-0/+14
| | | | | | | | | | Tegra210's PCIe controller has a bug that requires the PCA (performance counter) feature to be enabled. If this isn't done, accesses to device configuration space will hang the chip for tens of seconds. Implement the workaround.

* pci: tegra: use #address-/size-cells from DTStephen Warren2015-11-12-3/+30
| | | | | | | | | The number of cells used by each entry in the DT ranges property is determined by the #address-cells/#size-cells properties. Fix the code to respect this. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
* pci: tegra: clip RAM size to 32-bitsStephen Warren2015-11-12-1/+9
| | | | | | | | | Tegra peripherals can generally access a 32-bit physical address space, and I believe this applies to PCIe. Clip the PCI region that refers to DRAM so it fits into 32-bits to avoid issues. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
* lib/fdtdec: Fix compiling warning caused by changing fdt_addr_t typeYork Sun2015-08-06-5/+5
| | | | | | | | fdt_addr_t is changed to phys_addr_t. The format in debug should be updated to %pa to match the type. Signed-off-by: York Sun <yorksun@freescale.com> CC: Simon Glass <sjg@chromium.org>
* 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.
