2025-08-13gpio: remove gpiobus_attach_busAhmad Khalifa
Since gpiobus_attach_bus can attach the gpiobus child along with its children in the same bus pass, the parent controller's reference to gpiobus might not be set by the time the children need it. Instead, drivers should use gpiobus_add_bus and explicitly call bus_attach_children.

2020-08-20Remove the long obsolete ufm driver.Warner Losh
It was a driver for a USB FM tuner that was available in the market in 2002. I wrote the driver in 2003. I've not used it since 2005 or so, so it's time to retire this driver. No userland code ever interfaced to the special device it created. There's no user base: the last bug I received on this driver was in 2004. Relnotes: Yes Notes: svn path=/head/; revision=364432
2020-08-12cp2112: a number of cleanups and improvementsAndriy Gapon

The parent driver claims the USB device and creates two child devices. One acts as a GPIO controller and the other is an I2C controller. Tested with CP2112 revision F02. Both features seem to work.

This driver hasn't been relevant in almost 15 years. It was for a product on the shelves for about 6 months in 2003/2004. I've not updated the driver since then, and have had nobody talk to me about it since maybe 2006 or 2007. It doesn't implement a standard interface, and can be better done with libusb. All the action has moved to webcamd for newer, more fully featured hardware. It makes no appearances in the nycbug dmesg archive.

2017-11-27sys/dev: further adoption of SPDX licensing ID tags.Pedro F. Giffuni
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. Notes: svn path=/head/; revision=326255

2015-01-06In order to reduce use of M_EXT outside of the mbuf allocator andRobert Watson
socket-buffer implementations, introduce a return value for MCLGET() (and m_cljget() that underlies it) to allow the caller to avoid testing M_EXT itself. Update all callers to use the return value. With this change, very few network device drivers remain aware of M_EXT; the primary exceptions lie in mbuf-chain pretty printers for debugging, and in a few cases, custom mbuf and cluster allocation implementations. NB: This is a difficult-to-test change as it touches many drivers for which I don't have physical devices. Instead we've gone for intensive review, but further post-commit review would definitely be appreciated to spot errors where changes could not easily be made mechanically, but were largely mechanical in nature.
