[PATCH v5] PCI: PTM Driver

["Yong, Jonathan" <jonathan.yong@intel.com>]

Hello LKML,

This is a preliminary implementation of the PTM support driver. This driver
has only been tested against a virtual PCI bus since there are no known
endpoints utilizing it yet.

Please CC me as I am not subscribed to the list.
Thanks.


Changes since v1:
* Moved register constants to pci_regs.h
* Use pci_dev to hold PTM status
* PTM initialization now done top-down hierarchy wise.

Changes since v2:
* Added missing void return in the pci_ptm_init inline stub.

Changes since v3:
* Clearing CONFIG_PCIE_PTM now completely prevents the driver from being built.
* Renamed pci_*_ptm_sysfs to pcie_ptm_*_sysfs_dev_files for consistency.
* Removed useless prototypes.
* Driver no longer checks PTM capability version
* PCI_EXT_CAP_ID_MAX updated to include PTM (0x1F)

Changes since v4:
* Using pci=noptm kernel parameter now disables ptm activation like other pci features.
* Module param to disable ptm driver at runtime removed.
* Sysfs file entries removed.
