Subject[PATCH v6 0/3] PCI: Precision Time Measurement support
This is a slightly different proposal for the PTM support Jonathan
proposed here:

I split this into three pieces mostly for ease in reviewing. They
could all be squashed:

- Enable PTM in root ports and switches automatically at boot
- Enable PTM in endpoints when requested by driver
- Add clock granularity information

I have some open questions about how PTM works on Root Complex
Integrated Endpoints and whether we should enable it automatically
even without a driver request. And I probably left out some details
of the clock granularity computation, so treat this as more of an RFC
than anything.



Bjorn Helgaas (2):
PCI: Add pci_enable_ptm() for drivers to enable PTM on endpoints
PCI: Add PTM clock granularity information

Jonathan Yong (1):
PCI: Add Precision Time Measurement (PTM) support
