spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD

2023-05-12T16:44:03+00:00

The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch
up to that fact and revert to their recommended match of BSD-2-Clause.

sys/dev: further adoption of SPDX licensing ID tags.

2017-11-27T14:52:40+00:00

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

[arswitch] add phy debugging to the internal PHY read/write functions.

2017-05-23T03:48:42+00:00

[arswitch] extend the debug support to be configurable at runtime.

2016-08-07T01:32:37+00:00

* remove the DEBUG ifdef; defining it is too far reaching throughout
  the whole system;
* add a bitmask in the softc for controlling debugging;
* .. enable said debugging as a sysctl;
* add bitmaps for register access, reset and vlans.

TODO:

* Now that the debug statements are configurable, we definitely could
  do with more debugging
* Move the debugging into the top-level etherswitch driver and have
  sub-drivers obey.

[mdio] migrate mdiobus out of etherswitch and into a top-level device of its own.

2015-12-26T02:31:39+00:00

The mdio driver interface is generally useful for devices that require
MDIO without the full MII bus interface. This lifts the driver/interface
out of etherswitch(4), and adds a mdio(4) man page.

Fix up support for the AR8327.

2015-03-08T03:53:36+00:00

* Even though I got the registers around "right", it seems
  I'm not tickling the MDIO access correctly for the internal PHY
  bus.  Some of the switches are fine poking at the external PHY
  registers; others aren't.  So, enable direct PHY bus access
  for the AR8327, and leave the existing code in place for the
  others.

* Go and shuffle the register access around.  Whilst here,
  restore the 2ms delay if changing page.

* Comment out some of the stub printf()s; there's some upcoming
  work to add port VLAN support.

Tested:

* AP135 development board
* Carambola2 - AR9331 SoC

Revert r268543.

We should probably fix sys/gpio.h instead.

Move iic.h to sys/ so that it's automatically installed in /usr/include/sys.

2014-07-12T01:04:10+00:00

This lets us call iic(4) ioctls without needing the kernel source code
and follows the same model of GPIO.

Teach the PHY register path about the different MDIO bus address
