ptp: tilegx: convert to the 64 bit get/set time methods.

2015-03-31T16:01:18+00:00

This driver is 64 bit only, and so this driver and device are ready
for 2038.  This patch changes the driver to the new PHC and also
carries the timespec64 parameter on out to the gxio_mpipe_get-
set_timestamp functions, making explicit the fact that the tv_sec
field is 64 bits wide.

Not even compile tested.

Pull Tile arch updates from Chris Metcalf:
 "These changes bring in a bunch of new functionality that has been
  maintained internally at Tilera over the last year, plus other stray
  bits of work that I've taken into the tile tree from other folks.

  The changes include some PCI root complex work, interrupt-driven
  console support, support for performing fast-path unaligned data
  fixups by kernel-based JIT code generation, CONFIG_PREEMPT support,
  vDSO support for gettimeofday(), a serial driver for the tilegx
  on-chip UART, KGDB support, more optimized string routines, support
  for ftrace and kprobes, improved ASLR, and many bug fixes.

  We also remove support for the old TILE64 chip, which is no longer
  buildable"

tilegx: provide kernel support for the tilegx UART shim

2013-09-03T18:50:36+00:00

The TILE-Gx chip includes an on-chip UART.  This change adds support
for using the UART from within the kernel.  The UART shim has more
functionality than is exposed here, but to keep the kernel code and
binary simpler, this is a subset of the full API designed to enable
a standard Linux tty serial driver only.

tile PCI RC: support more MSI-X interrupt vectors

2013-08-06T16:55:24+00:00

To support PCIe devices with higher number of MSI-X interrupt vectors,
e.g. 16 for the LSI RAID card, enhance the Gx RC stack to provide more
MSI-X vectors by using the TRIO Scatter Queues, which provide 8 more
vectors in addition to ~10 from the Map Mem regions.

tile: support multiple mPIPE shims in tilegx network driver

2013-08-01T21:35:50+00:00

The initial driver support was for a single mPIPE shim on the chip
(as is the case for the Gx36 hardware).  The Gx72 chip has two mPIPE
shims, so we extend the driver to handle that case.

tile: gxio iorpc numbering change for TRIO interface

2012-09-24T19:11:53+00:00

An ABI numbering change was made in the hypervisor for Tilera's 4.1
MDE release (just shipped).  It's incompatible with the previous 4.0
release ABI numbering, so we track the new numbering going forward.
We plan to avoid modifying ABI numbering for these interfaces again.
