* ptp: pch: convert to the 64 bit get/set time methods.Richard Cochran2015-03-311-4/+4
| | | | | | | | | | | 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. Signed-off-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* PCI: Remove DEFINE_PCI_DEVICE_TABLE macro useBenoit Taine2014-08-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | 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> [bhelgaas: add semantic patch] Signed-off-by: Benoit Taine <benoit.taine@lip6.fr> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
* ptp: drivers: set the number of programmable pins.Richard Cochran2014-03-211-0/+1
| | | | | | | | | | | 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.

* ptp: link the phc device to its parent deviceRichard Cochran2012-09-221-1/+1
| | | | | | | | | | | 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.
