Input: tsc2007 - read "ti,poll-period" as u32grafted
The "ti,poll-period" property is documented as a normal uint32 cell.
The driver used a u64 helper, which makes the helper type disagree with
the schema even though the stored value is still small.
Read "ti,poll-period" with the u32 helper matching the documented DT
cell size.

SPDX-License-Identifier: GPL-2.0 + +================== +Linux X.25 Project +================== + +As my third year dissertation at University I have taken it upon myself to +write an X.25 implementation for Linux. My aim is to provide a complete X.25 +Packet Layer and a LAPB module to allow for "normal" X.25 to be run using +Linux. There are two sorts of X.25 cards available, intelligent ones that +implement LAPB on the card itself, and unintelligent ones that simply do +framing, bit-stuffing and checksumming. These both need to be handled by the +system. + +I therefore decided to write the implementation such that as far as the +Packet Layer is concerned, the link layer was being performed by a lower +layer of the Linux kernel and therefore it did not concern itself with +implementation of LAPB. Therefore the LAPB modules would be called by +unintelligent X.25 card drivers and not by intelligent ones, this would +provide a uniform device driver interface, and simplify configuration. + +To confuse matters a little, an 802.2 LLC implementation is also possible +which could allow X.25 to be run over an Ethernet (or Token Ring) and +conform with the JNT "Pink Book", this would have a different interface to +the Packet Layer but there would be no confusion since the class of device +being served by the LLC would be completely separate from LAPB. + +Just when you thought that it could not become more confusing, another +option appeared, XOT. This allows X.25 Packet Layer frames to operate over +the Internet using TCP/IP as a reliable link layer. RFC1613 specifies the +format and behaviour of the protocol. If time permits this option will also +be actively considered. + +A linux-x25 mailing list has been created at vger.kernel.org to support the +development and use of Linux X.25. It is early days yet, but interested +parties are welcome to subscribe to it. Just send a message to +majordomo@vger.kernel.org with the following in the message body: + +subscribe linux-x25 +end + +The contents of the Subject line are ignored. + +Jonathan + +g4klx@g4klx.demon.co.uk |
