this patch series implements PCIe speed changes for Tesla and newer.

The Kepler and Fermi bits are tested on my cards at home.

Karol Herbst (9):
  pci: add gk104 variant
  pci: add gf106 variant
  pci: implement generic code for PCIe speed change
  pci: implement pcie speed change for tesla
  pci: implement pcie speed change on Fermi
  pci: implement PCIe speed change for kepler+
  bios/perf: parse the pci speed from the bios for tesla and newer cards
  perf: add fields for pci speed and width and use it for the pstates
  perf: change pcie speed on pstate change
