Richard Cochran a043a72909 ptp: pch: convert to the 64 bit get/set time methods.
The device has a 64 bit clock register, where each clock tick is 32
nanoseconds, and so with this patch the driver is ready for the year
2038.

Compile tested only.

Benoit Taine 9baa3c34ac PCI: Remove DEFINE_PCI_DEVICE_TABLE macro use
We should prefer `struct pci_device_id` over `DEFINE_PCI_DEVICE_TABLE` to
meet kernel coding style guidelines.  This issue was reported by checkpatch.

A simplified version of the semantic patch that makes this change is as
follows (http://coccinelle.lip6.fr/):

// <smpl>

@@
identifier i;
declarer name DEFINE_PCI_DEVICE_TABLE;
initializer z;
@@

- DEFINE_PCI_DEVICE_TABLE(i)
+ const struct pci_device_id i[]
= z;

// </smpl>

Richard Cochran 4986b4f008 ptp: drivers: set the number of programmable pins.
This patch updates the many PTP Hardware Clock drivers with the
newly introduced field that advertises the number of programmable
pins. Some of these devices do have programmable pins, but the
implementation will have to wait for follow on patches.

Sahara 7d3ac5c779 ptp_pch: eliminate a number of sparse warnings
This fixes a number of sparse warnings like:
  warning: incorrect type in argument 2 (different address spaces)
    expected void volatile [noderef] <asn:2>*addr
    got unsigned int *<noident>

  warning: Using plain integer as NULL pointer

Additionally this fixes a warning from checkpatch.pl like:
  WARNING: sizeof pch_param.station should be sizeof(pch_param.station)

Richard Cochran 1ef761582c ptp: link the phc device to its parent device
PTP Hardware Clock devices appear as class devices in sysfs. This patch
changes the registration API to use the parent device, clarifying the
clock's relationship to the underlying device.
