cfea4862aa Comment out some pointless device open/close around reading device IDs.
FreeBSD ZFS port unlike OpenSolaris does not use device IDs, and does not
implement respective devid_*() fuctions.  It is pointless to open devices
just to close them back immediately.

d36599654d Do not configure all pins as outputs as this can lead to short circuits when
the GPIO pin is connected to a push button (or other devices).

Instead keep the boot loader settings.

Calling ar71xx_gpio_pin_configure() with DEFAULT_CAPS was probably a
mistake and was causing all the pins to be set as outputs.

20e87023bd Remove an old mistake of mine. This has sneak in the code i sent to gonzo
at that time, but AFAIK it is only used on routerboards.

Enabling GPIO_FUNC_SPI_CS[1|2]_EN will claim the use of gpio pins 0 and 1
respectivelly for use as SPI CS pins.

When really needed, this can still be enabled on kernel hints using the
function_set and function_clear knobs.

1e481e96a4 Add the lm75 i2c digital temperature sensor driver.
This driver supports the low and high precision models (9 and 11 bits) and
it will auto-detect the both variants.

The driver expose the temperature registers (actual temperature, shutdown
and hysteresys temperature) and also the configuration register.

It was tested on FDT systems: RPi, BBB and on non-FDT systems: AR71xx, with
both, hardware i2c controllers (when available) and gpioiic(4).

This provides a simple and cheap way for verifying the i2c bus on embedded
systems.

1a29a56861 Optimise host channel disabling:
- For non-periodic traffic we only need to wait two SOFs before
disabling the channel.
- Make sure we release the TX FIFO tracking level after the host
channel is disabled.
- Make sure the host channel state gets reset/disabled initially.
- Two minor code style changes.

65fc060c58 Add in support to optionally pin the swi threads.
Under enough load, the swi's can actually be preempted and migrated
to other currently free cores.  When doing RSS experiments, this lead
to the per-CPU TCP timers not lining up any more with the RX CPU said
flows were ending up on, leading to increased lock contention.

Since there was a little pushback on flipping them on by default,
I've left the default at "don't pin."

The other less obvious problem here is that the default swi
is also the same as the destination swi for CPU #0.  So if one
pins the swi on CPU #0, there's no default floating swi.

A nice future project would be to create a separate swi for
the "default" floating swi, as well as per-CPU swis that are
(optionally) pinned.

Tested:

* parallel TCP tests (2 x 1g unfortunately for now);
  CPU: Intel(R) Xeon(R) CPU E5-2650

Note:

This is based on some initial investigation into RSS/TCP stack lock
contention on FreeBSD-HEAD whilst at Netflix in January 2014.

d80cbf945b Multiple DWC OTG host mode related fixes and improvements:
- Rework how we allocate and free USB host channels, so that we only
allocate a channel if there is a real packet going out on the USB
cable.

- Use BULK type for control data and status, due to instabilities in
the HW it appears.

- Split FIFO TX levels into one for the periodic FIFO and one for the
non-periodic FIFO.

- Use correct HFNUM mask when scheduling host transactions. The HFNUM
register does not count the full 16-bit range.

- Correct START/COMPLETION slot for TT transactions. For INTERRUPT and
ISOCHRONOUS type transactions the hardware always respects the ODDFRM
bit, which means we need to allocate multiple host channels when
processing such endpoints, to not miss any so-called complete split
opportunities.

- When doing ISOCHRONOUS OUT transfers through a TT send all data
payload in a single ALL-burst. This deacreases the likelyhood for
isochronous data underruns.

- Fixed unbalanced unlock in case of "dwc_otg_init_fifo()" failure.

- Increase interrupt priority.

c75ba560d7 Fix TLR (Transport Layer Retry) support in the mps(4) and mpr(4) drivers.
TLR is necessary for reliable communication with SAS tape drives.

This was broken by change 246713 in the mps(4) driver.  It changed the
cm_data field for SCSI I/O requests to point to the CCB instead of the data
buffer.  So, instead, look at the CCB's data pointer to determine whether
or not we're talking to a tape drive.

Also, take the residual into account to make sure that we don't go off the
end of the request.

* Don't use CLOCK_MONOTONIC_PRECISE.  It's an unportable synonym for
