* w1: allow master IO commandsEvgeniy Polyakov2009-01-081-65/+77
| | | | | | | | | | | | | | | | | | | | | | | This small patchset extendes existing commands with reset, master IO and status messages. Reset is used to reset the bus for given master device, master IO command allows to initiate IO against bus itself not selecting slave device first, which can be used to probe the device for example. And status messages carry command completion status back to the userspace (namely very useful to get -ENODEV from when requested device was not found). Great thanks to Paul Alfille of OWFS for testing and commands suggestions. This patch: Allow starting of IO not against already found slave devices, but against the bus itself, which can be used for example to probe devices.

* w1: list slaves commandsEvgeniy Polyakov2009-01-081-17/+85
| | | | | | | | | | | Initiates search (or alarm search) and returns all found devices to userspace. Found devices are not added into the system (i.e. they are not attached to family devices or bus masters), it will be done via (if was not done yet) usual timed searching.

* w1: add list masters w1 commandEvgeniy Polyakov2009-01-081-0/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch series introduces and extends several userspace commands used with netlink protocol. Touch block command allows to write data and return sampled data to the userspace. Extended search and alarm seach commands to return list of slave devices found during given search. List masters command allows to send all registered master IDs to the userspace. Great thanks to Paul Alfille (owfs) who tested this implementation and wrote w1-to-network daemon http://sourceforge.net/projects/w1repeater/ and Frederik Deweerdt and Randy Dunlap for review. This patch: Returns list of registered bus master devices.

* [PATCH] w1: Userspace communication protocol over connector.Evgeniy Polyakov2006-06-221-30/+185
| | | | | | | | | | | There are three types of messages between w1 core and userspace: 1. Events. They are generated each time new master or slave device found either due to automatic or requested search. 2. Userspace commands. Includes read/write and search/alarm search comamnds. 3. Replies to userspace commands. From: Evgeniy Polyakov <johnpol@2ka.mipt.ru> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
