This series is the result of that with some very nice side effects. First, we now have a new test to check for proper repeated starts between messages in a transfer which will also improve versioning (patch 3). Also, the state of the testunit can now be checked (patch 4). Patch 1 makes the state machine a little easiert to follow. And patch 2 improves documentation. The patches are based on Linus' tree close to rc3 and has been tested on a Renesas Lager board (R-Car H2) and a Renesas Falcon board (R-Car V3U). Looking forward to comments. Once we got this in, I will send out the SMBusAlert additions. They do work already, they just need some documentation. Changes since v1: * patch 2 added to improve documentation * added newline to the version string to make its printout "self-contained" * for reading the new version string, the shell one liner to print ASCII directly has been removed. Now we use a new feature of i2ctransfer. Note, the docs mention version 4.4 already which is not out yet, but it will be by the time 6.11 is released (tm). * rebased, dependencies are now in Linus' tree Happy hacking!
