w1: allow master IO commands

2009-01-08T16:31:13+00:00

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 commands

2009-01-08T16:31:13+00:00

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 command

2009-01-08T16:31:13+00:00

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.

w1: fix slave selection on big-endian systems

2008-12-23T23:58:21+00:00

During test of the w1-gpio driver i found that in "w1.c:679
w1_slave_found()" the device id is converted to little-endian with
"cpu_to_le64()", but its not converted back to cpu format in "w1_io.c:293
w1_reset_select_slave()".

Based on a patch created by Andreas Hummel.
