4941b395b3 [PATCH] I2C: I2C controllers go into right place on sysfs
I2C creates some sysfs nodes in the wrong places:  not as children of parent
controllers, but as their peers (!).  This puts them into the right place
always, instead of just when the adapter is on the platform bus.

02dd7ae289 [PATCH] i2c-i801: Merge setup function
i2c-i801: Merge setup function

Merge i801_setup into i801_probe, as it doesn't make much sense to
have them split. This lets us handle errors better. Christopher
Hellwig had been suggesting this back in March 2003 when the driver
was merged.

Also drop two useless debug messages (revision and base address can be
obtained from lspci, procfs or sysfs.)

54aaa1ca10 [PATCH] I2C: i2c-piix4: Remove the fix_hstcfg parameter
This patch removes the fix_hstcfg option from the driver and related
SMBus Interrupt Select register magic because now we know what are
valid values for this register. This patch updates the documentation
and adds new IRQ mode check so we are sure not to miss any new
"unusual" value.

The PCI quirk for users of fix_hstcfg was not developed because the
chipset lacks of subsystem ID registers and DMI is stated "To be
filled". Impact to existing systems is minimal because the problem
showed up on motherboards like 10 years back. On the other hand users
of newer Serverworks and HT1000 systems won't be misleaded by the
message suggesting to try the fix_hstcfg any more.

5e9f4f2e5a [PATCH] I2C: m41t00: Add support for the ST M41T81 and M41T85
This patch adds support for the ST m41t81 and m41t85 i2c rtc chips
to the existing m41t00 driver.

Since there is no way to reliably determine what type of rtc chip
is in use, the chip type is passed in via platform_data.  The i2c
address and square wave frequency are passed in via platform_data
as well.  To accommodate the use of platform_data, a new header
file include/linux/m41t00.h has been added.

The m41t81 and m41t85 chips halt the updating of their time registers
while they are being accessed.  They resume when a stop condition
exists on the i2c bus or when non-time related regs are accessed.
To make the best use of that facility and to make more efficient
use of the i2c bus, this patch replaces multiple i2c_smbus_xxx calls
with a single i2c_transfer call.

95563d343f [PATCH] scx200_acb: Fix for the CS5535 errata
This is a fix for the CS5535 errata 111:

When the SMBus controller tries to access a non-existing device, it sets
the NEGACK bit, SMBus I/O offset 01h[4], to 1 after it detects no
acknowledge at the ninth clock.  The specification states that the bit
can be cleared by writing a 1 to it, but under certain circumstances it
is possible for this bit to not clear.

Writing a 0 to the bit resets the internal state machine and clears the
issue.

Since all writable bits in ACBST are W1C bits (write-one-to-clear) the
second write doesn't affect any other logic except the buggy NEGACK
state machine. The second write clears an internal register which is
responsible for "overwriting" the NEGACK bit in ACBST.

Fix for bug #6395:

Fail to resume on Tecra M2 with ADM1032 and Intel 82801DBM

The BIOS of the Tecra M2 doesn't like it when it has to reboot or resume
after the i2c-i801 driver has left the SMBus in PEC mode.  The most simple
fix is to clear the PEC bit after after every transaction.  That's what
this driver was doing up to 2.6.15 (inclusive).

slave drivers that have lengthy probe routines (e.g. hwmon drivers).

cdf263f1c5 [PATCH] I2C: fix sx200_acb build on other arches
scx200_acb is only useful on a few Geode-based systems, and won't
compile on non-x86 systems due to the lack of asm/msr.h, as reported
by Andrew Morton. Thus, we should make that driver depend on X86.
