  • 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

  • Nice cleanup spotted by Adrian Bunk, which was lost due to moving to the
    completely new functionality.

    Shame-shame-shame on me.

  • 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.

  • Special file in each w1 slave device's directory called "rw" is created
    each time new slave and no appropriate w1 family is registered.
    "rw" file supports read and write operations, which allows to perform
    almost any kind of operations. Each logical operation is a transaction
    in nature, which can contain several (two or one) low-level operations.
    Let's see how one can read EEPROM context:
    1. one must write control buffer, i.e. buffer containing command byte
    and two byte address. At this step bus is reset and appropriate device
    is selected using either W1_SKIP_ROM or W1_MATCH_ROM command.
    Then provided control buffer is being written to the wire.
    2. reading. This will issue reading eeprom response.

    It is possible that between 1. and 2. w1 master thread will reset bus for
    searching and slave device will be even removed, but in this case 0xff will
    be read, since no device was selected.

  • I've created reconnect feature - if on start there are no registered families
    all new devices will have defailt family, later when driver for appropriate
    family is loaded, slaves, which were faound earlier, will still have defult
    family instead of right one. Reconnect feature will force control thread to run
    through all master devices and all slaves found and search for slaves with
    default family id and try to reconnect them.

    It does not store newly registered family and does not check only those slaves
    which have reg_num.family the same as being registered one - all slaves with
    default family are reconnected.

  • …ble periodic searches.

    Adds a sysfs entry (w1_master_search) that allows you to disable/enable
    periodic searches.

  • Removed some fields which are not required.
    First step for writing operations.
    Now only read and read name remain.
    Patch depends on w1 cleanups patch.

  • - white space changes.
    - list_for_each_entry/list_for_each_entry_safe and reverse changes.
    - small coding style changes.
    - removed redundant NULL checks.
    - use attribute group and macros instead of direct device attributes.
    Patch is havily based on work from Adrian Bunk and Dmitry Torokhov,
    thanks guys.

  • 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!
