2019-04-25docs: serial: convert docs to ReST and rename to *.rstMauro Carvalho Chehab
The converted files are focused at the Kernel internal API, so, this is a good candidate for the kernel API set of books. The conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.

2018-11-20Documentation: Use "while" instead of "whilst"Will Deacon
Whilst making an unrelated change to some Documentation, Linus sayeth: | Afaik, even in Britain, "whilst" is unusual and considered more | formal, and "while" is the common word. | | [...] | | Can we just admit that we work with computers, and we don't need to | use þe eald Englisc spelling of words that most of the world never | uses? dictionary.com refers to the word as "Chiefly British", which is probably an undesirable attribute for technical documentation. Replace all occurrences under Documentation/ with "while".

2016-08-18Documentation: rs485: Do not define manually the ioctlRicardo Ribalda Delgado
It is not a very good practice to define the IOCTL manually instead of using the header file. Fix it on the documentation example. Signed-off-by: Ricardo Ribalda Delgado <ricardo.ribalda@gmail.com> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
2015-06-12Doc: serial-rs485.txt: update RS485 driver interfaceBaruch Siach
Since commit a5f276f10ff7 (serial_core: Handle TIOC[GS]RS485 ioctls., 2014-11-06) serial_core handles RS485 ioctls. Drivers only need to implement the rs485_config callback. Update serial-rs485.txt to reflect these changes. Signed-off-by: Baruch Siach <baruch@tkos.co.il> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2011-11-15RS485: fix inconsistencies in the meaning of some variablesClaudio Scordino
The crisv10.c and the atmel_serial.c serial drivers intepret the fields of the serial_rs485 structure in a different way. In particular, crisv10.c uses SER_RS485_RTS_AFTER_SEND and SER_RS485_RTS_ON_SEND for the voltage of the RTS pin; atmel_serial.c, instead, uses these values to know if a delay must be set before and after sending. This patch makes the usage of these variables consistent across all drivers and fixes the Documentation as well. From now on, SER_RS485_RTS_AFTER_SEND and SER_RS485_RTS_ON_SEND will be used to set the voltage of the RTS pin (as in the crisv10.c driver); the delay will be understood by looking only at the value of delay_rts_before_send and delay_rts_after_send.

2011-08-24atmel_serial: RS485: receiving enabled when sending dataBernhard Roth
By default the atmel_serial driver in RS485 mode disables receiving data until all data in the send buffer has been sent. This flag allows to receive data even whilst sending data.
