* clk: Move clock code in dev/clkEmmanuel Vadot2024-01-101-1/+1
| | | | | | | | | | | We've removed kernel option EXT_RESOURCES almost two years ago. While it was ok to have some code under a common 'extres' subdirectory at first, we now have a lot of consumer of it and we made it mandatory so no need to have it under a cryptic name.

* sys/dev: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-271-0/+2
| | | | | | | | | | | | | | | 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
* Add support for the uart classes to set their default register shift value.Andrew Turner2015-04-111-1/+2
| | | | | | | | | | | | | | This is needed with the pl011 driver. Before this change it would default to a shift of 0, however the hardware places the registers at 4-byte addresses meaning the value should be 2. This patch fixes this for the pl011 when configured using the fdt. The other drivers have a default value of 0 to keep this a no-op. MFC after: 1 week Notes: svn path=/head/; revision=281438

| | | | | | | | | | | | | | | console, it calls the grab functions. These functions should turn off the RX interrupts, and any others that interfere. This makes mountroot prompt work again. If there's more generalized need other than prompting, many of these routines should be expanded to do those new things. Should have been part of r260889, but waasn't due to command line typo.

* Fix low-level uart drivers that set their fifo sizes in the softc too late.Ian Lepore2013-04-011-3/+3
| | | | | | | | | | | | uart(4) allocates send and receiver buffers in attach() before it calls the low-level driver's attach routine. Many low-level drivers set the fifo sizes in their attach routine, which is too late. Other drivers set them in the probe() routine, so that they're available when uart(4) allocates buffers. This fixes the ones that were setting the values too late by moving the code to probe(). Notes: svn path=/head/; revision=248965
