30091404af i2c-algo-pcf: Add adapter hooks around xfer begin and end
Some I2C bus implementations need to synchronize with external
entities, such as system firmware, which might also be programming the
same I2C bus.

In order to facilitate this add ->xfer_begin() and ->xfer_end() hooks
which are invoked around pcf_xfer().

[JD: Make these hooks optional.]

0573d11b2b i2c-algo-pcf: Multi-master lost-arbitration improvement
Improve lost-arbitration handling of PCF8584.  This is necessary for
support of a currently out-of-kernel driver for Sun Microsystems E250
environmental management; perhaps others.

6408a8338c i2c-algo-pcf: Delete broken 10-bit address support
The 10-bit address support in i2c-algo-pcf is so heavily broken that
it can't have ever been used. Nobody ever complained, so I'll take it
that nobody needs it. Let's just delete it.

96de0e252c Convert files to UTF-8 and some cleanups
* Convert files to UTF-8.

  * Also correct some people's names
    (one example is Eißfeldt, which was found in a source file.
    Given that the author used an ß at all in a source file
    indicates that the real name has in fact a 'ß' and not an 'ss',
    which is commonly used as a substitute for 'ß' when limited to
    7bit.)

  * Correct town names (Goettingen -> Göttingen)

  * Update Eberhard Mönkeberg's address (http://lkml.org/lkml/2007/1/8/313)

3269711b76 i2c: Discard the i2c algo del_bus wrappers
They are all only calling i2c_del_adapter, so we may as well do
it directly.

b39ad0cf7c [PATCH] i2c: Handle i2c_add_adapter failure in i2c algorithm drivers
Content-Disposition: inline; filename=i2c-algo-error-handling-fix.patch

It is possible for i2c_add_adapter() to fail.  Several I2C algorithm
drivers ignore that fact.  This (compile-tested only) patch fixes them.

c7a46533ff [PATCH] I2C: Kill i2c_algorithm.id (5/7)
Merge the algorithm id part (16 upper bits) of the i2c adapters ids
into the definition of the adapters ids directly. After that, we don't
need to OR both ids together for each i2c_adapter structure.

There are no more users of i2c_algorithm.id, so we can finally drop
this structure member.

87c3d7a8bc [PATCH] I2C: Kill i2c_algorithm.id (3/7)
Don't rely on i2c_algorithm.id to alter the i2c adapter's id, use the
I2C_ALGO_* value directly instead, because i2c_algorithm will soon
have no id member no more.

The name member of the i2c_algorithm is never used, although all
drivers conscientiously fill it. We can drop it completely, this
structure doesn't need to have a name.

1da177e4c3 Linux-2.6.12-rc2
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!
