2008-10-16W1: w1_family, remove unused variable need_exitDavid Fries
Removed the w1_family structure member variable need_exit. It was only being set and never used. Even if it were to be used it is a polling type operation.

2008-10-16W1: fix deadlocks and remove w1_control_threadDavid Fries
w1_control_thread was removed which would wake up every second and process newly registered family codes and complete some final cleanup for a removed master. Those routines were moved to the threads that were previously requesting those operations. A new function w1_reconnect_slaves takes care of reconnecting existing slave devices when a new family code is registered or removed. The removal case was missing and would cause a deadlock waiting for the family code reference count to decrease, which will now happen. A problem with registering a family code was fixed. A slave device would be unattached if it wasn't yet claimed, then attached at the end of the list, two unclaimed slaves would cause an infinite loop. The struct w1_bus_master.search now takes a pointer to the struct w1_master device to avoid searching for it, which would have caused a lock ordering deadlock with the removal of w1_control_thread.

This patch contains the following possible cleanups: - the following file did't #include the header with the prototypes for it's global functions: - w1_int.c - #if 0 the following unused global function: - w1_family.c: w1_family_get() - make the following needlessly global functions static: - w1_family.c: __w1_family_put() - w1_io.c: w1_delay() - w1_io.c: w1_touch_bit() - w1_io.c: w1_read_8() - remove the following unused EXPORT_SYMBOL's: - w1_family.c: w1_family_put - w1_family.c: w1_family_registered Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Evgeniy Polyakov <johnpol@2ka.mipt.ru> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-06-22[PATCH] w1: Userspace communication protocol over connector.Evgeniy Polyakov
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.

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!
