* sys/dev: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-277-1/+15
| | | | | | | | | | | | | | | 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

* Wait for DesignWare UART transfers completion before accessing line controlZbigniew Bodek2013-10-261-0/+1
| | | | | | | | | | | | | | | | When using DW UART with BUSY detection it is necessary to wait until all serial transfers are finished before manipulating the line control. LCR will not be affected when UART is busy. In addition, if Divisor Latch Access Bit is being set in order to modify UART divisors: 1. We will get BUSY interrupt if interrupts are enabled. 2. Because LCR will not be affected the THR and (even worse) IER contents will be corrupted. This will lead to console hang. Approved by: cognet (mentor) Notes: svn path=/head/; revision=257170
* Add support for A10 uart.Ganbold Tsagaankhuu2013-03-011-0/+1
| | | | | | | | | | | | | | | A10 uart is derived from Synopsys DesignWare uart and requires to read Uart Status Register when IIR_BUSY has detected. Also this change includes FDT check, where it checks device specific properties defined in dts and sets the busy_detect variable. broken_txfifo is also needed to be set in order to make it work for A10 uart case.

| | | | | | | | | | | | Use it to reset controller and to select data rate. According to Intel 80277AA datasheet, software reset behaves the same as DOR reset except that it is self clearing. National Semiconductor PC8477B datasheet says the same.

| | | | | | | | | | | | | | | | - Rename REG_DL to REG_DLL and REG_DLH. - Always treat DLL and DLH as two separate 8-bit registers instead of one 16-bit register. Additionally, remove the probe for the high 4 bits of IER being 0 and don't assume we can always read/write 0 to/from those bits.

* Moved the definitions of the bits in the ns*50 registers from sioreg.hBruce Evans2003-09-161-0/+85

The bits in the registers have no driver or bus dependencies but they but the offsets of the registers in bus space are very bus-dependent.

* The uart(4) driver is an universal driver for various UART hardware.Marcel Moolenaar2003-09-062-0/+572
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It improves on sio(4) in the following areas: o Fully newbusified to allow for memory mapped I/O. This is a must for ia64 and sparc64, o Machine dependent code to take full advantage of machine and firm- ware specific ways to define serial consoles and/or debug ports. o Hardware abstraction layer to allow the driver to be used with various UARTs, such as the well-known ns8250 family of UARTs, the Siemens sab82532 or the Zilog Z8530. This is especially important for pc98 and sparc64 where it's common to have different UARTs, o The notion of system devices to unkludge low-level consoles and remote gdb ports and provides the mechanics necessary to support the keyboard on sparc64 (which is UART based). o The notion of a kernel interface so that a UART can be tied to something other than the well-known TTY interface. This is needed on sparc64 to present the user with a device and ioctl handling suitable for a keyboard, but also allows us to cleanly hide an UART when used as a debug port. Following is a list of features and bugs/flaws specific to the ns8250 family of UARTs as compared to their support in sio(4): o The uart(4) driver determines the FIFO size and automaticly takes advantages of larger FIFOs and/or additional features. Note that since I don't have sufficient access to 16[679]5x UARTs, hardware flow control has not been enabled. This is almost trivial to do, provided one can test. The downside of this is that broken UARTs are more likely to not work correctly with uart(4). The need for tunables or knobs may be large enough to warrant their creation. o The uart(4) driver does not share the same bumpy history as sio(4) and will therefore not provide the necessary hooks, tweaks, quirks or work-arounds to deal with once common hardware. To that extend, uart(4) supports a subset of the UARTs that sio(4) supports. The question before us is whether the subset is sufficient for current hardware. o There is no support for multiport UARTs in uart(4). The decision behind this is that uart(4) deals with one EIA RS232-C interface. Packaging of multiple interfaces in a single chip or on a single expansion board is beyond the scope of uart(4) and is now mostly left for puc(4) to deal with. Lack of hardware made it impossible to actually implement such a dependency other than is present for the dual channel SAB82532 and Z8350 SCCs. The current list of missing features is: o No configuration capabilities. A set of tunables and sysctls is being worked out. There are likely not going to be any or much compile-time knobs. Such configuration does not fit well with current hardware. o No support for the PPS API. This is partly dependent on the ability to configure uart(4) and partly dependent on having sufficient information to implement it properly. As usual, the manpage is present but lacks the attention the software has gotten. Notes: svn path=/head/; revision=119815
