* [PATCH] i2c-i801: Fix block transaction poll loopsJean Delvare2006-06-22
| | | | | | | | | | | | i2c-i801: Fix block transaction poll loops Two of the three poll loops have the poll and sleep swapped, causing an extra sleep to occur after the polled condition is fulfilled. In practice, this doubles the amount of sleep time for every block transaction. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* [PATCH] I2C: i2c-nforce2: Add support for the nForce4 MCP51 and MCP55Jean Delvare2006-06-22
| | | | | | | | | | | Add support for the new nForce4 MCP51 (also known as nForce 410 or 430) and nForce4 MCP55 to the i2c-nforce2 driver. Some code changes were required because the base I/O address registers have changed in these versions. Standard BARs are now being used, while the original nForce2 chips used non-standard ones.

* [PATCH] I2C: i2c-piix4: Remove the fix_hstcfg parameterRudolf Marek2006-06-22
| | | | | | | | | | | | | | | | | | | 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.

* [PATCH] scx200_acb: Fix for the CS5535 errataJordan Crouse2006-05-09
| | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | We can't pass a string on the stack to request_region. As soon as we leave the function that stack is gone and the string is lost.

| | | | | | | | | | | | | | | | | | 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). Thanks to Daniele Gaffuri for the very good report.

* [PATCH] i2c-parport: Make type parameter mandatoryMark M. Hoffman2006-04-14
| | | | | | | | | | | | | | | | This patch forces the user to specify what type of adapter is present when loading i2c-parport or i2c-parport-light. If none is specified, the driver init simply fails - instead of assuming adapter type 0. This alleviates the sometimes lengthy boot time delays which can be caused by accidentally building one of these into a kernel along with several i2c slave drivers that have lengthy probe routines (e.g. hwmon drivers).

* [PATCH] 2/5 powerpc: Rework PowerMac i2c part 2Benjamin Herrenschmidt2006-01-08
| | | | | | | | | | | | | | | | | | This is the continuation of the previous patch. This one removes the old PowerMac i2c drivers (i2c-keywest and i2c-pmac-smu) and replaces them both with a single stub driver that uses the new PowerMac low i2c layer. Now that i2c-keywest is gone, the low-i2c code is extended to support interrupt driver transfers. All i2c busses now appear as platform devices. Compatibility with existing drivers should be maintained as the i2c bus names have been kept identical, except for the SMU bus but in that later case, all users has been fixed. With that patch added, matching a device node to an i2c_adapter becomes trivial. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

This patch also extends & fix some bugs in the SMU driver related to i2c support and removes the clock spreading hacks from the pmac feature code rather than adapting them to the new API since they'll be replaced by the platform function code completely in patch 3/5 Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

The powermac udbg stuff gets enriched with some ADB capabilities and btext output. In addition, the early_init callback is now called on ppc32 as well, approx. in the same order as ppc64 regarding device-tree manipulations. The init sequences of ppc32 and ppc64 are getting closer, I'll unify them in a later patch. For now, you can force udbg to the scc using "sccdbg" or to btext using "btextdbg" on powermacs. I'll implement a cleaner way of forcing udbg output to something else than the autodetected OF output device in a later patch.
