8750197f0e [PATCH] i2c-viapro: Some adjustments
The big i2c-viapro SMBus driver update which went into 2.6.14-git1
introduced a few minor issues. Nothing critical, but I would like a
few adjustments to be merged in to fix the following problems:

* VIA should not be spelled Via.
* Frodo Looijaard and Philip Edelbrock did not write the i2c-viapro
  driver.
* When debugging is disabled, half of messages would be logged.
* Drop an unneeded masking.
* Some port reads can be avoided now that the transaction size is
  passed as a parameter to vt596_transaction().
* SMBus Receive Byte transactions are used for probing too (for
  EEPROMs), so hide errors on these too.

421ef47be2 [PATCH] i2c: SMBus PEC support rewrite, 2 of 3
This is my rewrite of the SMBus PEC support. The original
implementation was known to have bugs (credits go to Hideki Iwamoto
for reporting many of them recently), and was incomplete due to a
conceptual limitation.

The rewrite affects only software PEC. Hardware PEC needs very little
code and is mostly untouched.

Technically, both implementations differ in that the original one
was emulating PEC in software by modifying the contents of an
i2c_smbus_data union (changing the transaction to a different type),
while the new one works one level lower, on i2c_msg structures (working
on message contents). Due to the definition of the i2c_smbus_data union,
not all SMBus transactions could be handled (at least not without
changing the definition of this union, which would break user-space
compatibility), and those which could had to be implemented
individually. At the opposite, adding PEC to an i2c_msg structure
can be done on any SMBus transaction with common code.

Advantages of the new implementation:

* It's about twice as small (from ~136 lines before to ~70 now, only
  counting i2c-core, including blank and comment lines). The memory
  used by i2c-core is down by ~640 bytes (~3.5%).

* Easier to validate, less tricky code. The code being common to all
  transactions by design, the risk that a bug can stay uncovered is
  lower.

* All SMBus transactions have PEC support in I2C emulation mode
  (providing the non-PEC transaction is also implemented). Transactions
  which have no emulation code right now will get PEC support for free
  when they finally get implemented.

* Allows for code simplifications in header files and bus drivers
  (patch follows).

Drawbacks (I guess there had to be at least one):

* PEC emulation for non-PEC capable non-I2C SMBus masters was dropped.
  It was based on SMBus tricks and doesn't quite fit in the new design.
  I don't think it's really a problem, as the benefit was certainly
  not worth the additional complexity, but it's only fair that I at
  least mention it.

Lastly, let's note that the new implementation does slightly affect
compatibility (both in kernel and user-space), but doesn't actually
break it. Some defines will be dropped, but the code can always be
changed in a way that will work with both the old and the new
implementations. It shouldn't be a problem as there doesn't seem to be
many users of SMBus PEC to date anyway.

3634ff6a32 [PATCH] i2c: Fix i2c-elektor on Alpha
This patch updates the i2c-elektor driver, enabling it to compile
cleanly, load and run.  The key change is that it uses the new
__iomem/iowrite8/ioread8 functions to abstract the direct or
memory-mapped variants of register access.  Also, the original driver
would crash on module load on the Alpha because the PCI memory region
was not remapped into kernel memory.

I have managed the following testing:

* compiled and tested it on my Alpha UP2000+ system.
* compiles cleanly for x86 but I don't have the hardware to test.

I2C_SMBUS_I2C_BLOCK_MAX has always been defined to the same value as
I2C_SMBUS_BLOCK_MAX, and this will never change: setting it to a lower
value would make no sense, setting it to a higher value would break
i2c_smbus_data compatibility. There is no point in changing
i2c_smbus_data to support larger block transactions in SMBus mode, as
no SMBus hardware supports more than 32 byte blocks. Thus, for larger
transactions, direct I2C transfers are the way to go.

* Fix broken comments (some copied from i2c-piix4.)
* Centralize the unsupported command error case in vt596_access.
  That way we'll catch all unsupported commands, not only
  I2C_SMBUS_PROC_CALL.
* Refactor some code.
* Convert some dev_dbg into dev_err. Errors better be reported even in
  non-debug mode.
* Do not verify that the final reset succeeded. It'll be checked at
  the beginning of the next transaction anyway.
* Use the driver name to reserve the I/O region.
* Do not print the contents of the SMBREV register, it reads 0 on all
  chips I've seen so far.
* Some other minor fixes all over the place.

5c50d18859 [PATCH] i2c: Several PEC-related fixes in software SMBus emulation
Fix several errors in I2C SMBus emulation when PEC is used:
* Weird logic error in SMBus Write Word transactions.
* Wrong buffer size, affecting SMBus Block Write transactions.
* Potential buffer overrun in SMBus Block Write transactions.

4366dc946c [PATCH] i2c: Adjust i2c_probe() for busses without SMBUS_QUICK
Move the check for SMBUS_QUICK in i2c_probe() after the forced
addresses have been handled. This makes it possible for a driver to
leave the probed address lists empty, only providing forced addresses,
and get i2c_probe to work even if the bus doesn't support SMBUS_QUICK.

d6072f842a [PATCH] i2c: Reuse name strings in i2c bus drivers
Clean up name string usage in 12 i2c bus drivers:
* Use the i2c_adapter name for requesting the I/O region rather than
  redefining a new string.
* Do not initialize the i2c_adapter name to "unset".
This should save a few data bytes here and there.
