* terasic_mtl: kill off final dummy keyboard driverKyle Evans2019-12-231-16/+0
| | | | | | | | | | | | | | The rest were removed in r355936, which speculated that the cause of this phenomenon was due to an inability to have an empty linker set. The comment included with this one shows that this was, in fact, not the reason. Regardless, syscons no longer seems to have an issue with not having any keyboard drivers and in-fact ignores the keyboard probe anyways. X-MFC-With: r355936 Notes: svn path=/head/; revision=356045

* sys/dev: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-2712-0/+24
| | | | | | | | | | | | | | | 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

* Follow r261352 by updating all drivers which are children of simplebusIan Lepore2014-02-022-0/+6
| | | | | | | | | | | | | | | | to check the status property in their probe routines. Simplebus used to only instantiate its children whose status="okay" but that was improper behavior, fixed in r261352. Now that it doesn't check anymore and probes all its children; the children all have to do the check because really only the children know how to properly interpret their status property strings. Right now all existing drivers only understand "okay" versus something- that's-not-okay, so they all use the new ofw_bus_status_okay() helper. Notes: svn path=/head/; revision=261410

* Add terasic_mtl(4), a device driver for the Terasic Multi-Touch LCD,Robert Watson2012-08-257-0/+1632
used with Terasic's DE-4 and other similar FPGA boards. This display is 800x480 and includes a capacitive touch screen, multi-touch gesture recognition, etc. This device driver depends on a Cambridge- provided IP core that allows the MTL device to be hooked up to the Altera Avalon SoC bus, and also provides a VGA-like text frame buffer. Although it is compiled as a single device driver, it actually implements a number of different device nodes exporting various aspects of this multi-function device to userspace: - Simple memory-mapped driver for the MTL 24-bit pixel frame buffer. - Simple memory-mapped driver for the MTL control register set. - Simple memory-mapped driver for the MTL text frame buffer. - syscons attachment for the MTL text frame buffer. This driver attaches directly to Nexus as is common for SoC device drivers, and for the time being is considered BERI-specific, although in principle it might be used with other hard and soft cores on Altera FPGAs. Control registers, including touchscreen input, are simply memory mapped; in the future it would be desirable to hook up a more conventional device node that can stream events, support kqueue(2)/ poll(2)/select(2), etc. This is the first use of syscons on MIPS, as far as I can tell, and there are some loose ends, such as an inability to use the hardware cursor. More fundamentally, it appears that syscons(4) assumes that either a host is PC-like (i386, amd64) *or* it must be using a graphical frame buffer. While the MTL supports a graphical frame buffer, using the text frame buffer is preferable for console use. Fixing this issue in syscons(4) requires non-trivial changes, as the text frame buffer support assumes that direct memory access can be done to the text frame buffer without using bus accessor methods, which is not the case on MIPS. As a workaround for this, we instead double-buffer and pretend to be a graphical frame buffer exposing text accessor methods, leading to some quirks in syscons behaviour.
