spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD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

pbio: Remove unused devclass argument to DRIVER_MODULE.

pbio: Add locking and remove D_NEEDGIANT.

2022-05-05T23:40:04+00:00

Use a sx lock to permit uiomove directly into/out of the the per-port
buffers.  In addition, the sx lock provides a stronger guarantee that
I think this driver wants which is to single-thread read and write
calls even while paused.  Finally, replace tsleep with dummy wait
channels with calls to pause_sig to more clearly communicate the
intent.

pbio: Return BUS_PROBE_DEFAULT from probe instead of 0.

2022-05-05T23:39:19+00:00

0 should only be returned from probe in legacy drivers that need to
preserve softc state between probe and attach.

pbio: Axe bus_space tag/handle using bus_read/write_1 instead.

pbio: Store softc in si_drv1 for character devices.

2022-05-05T23:38:25+00:00

The port number is still stored in the unit (si_drv0) but is the
entire unit value now.

While here, removed checks for NULL softc since those can never happen
from cdevsw routines.  This also resulted in the close method becoming
a no-op, so it has been removed.

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.
