2013-02-11i2c: sis630: fix behavior after collisionAmaury Decrême1-6/+1
Datasheet on collision: SMBus Collision (SMBCOL_STS) This bit is set when a SMBus Collision condition occurs and SMBus Host loses in the bus arbitration. The software should clear this bit and re-start SMBus operation. As the status will be cleared in transaction_end, we can remove the sis630_write and prepare to return -EAGAIN to retry.

2012-01-13module_param: make bool parameters really bool (drivers & misc)Rusty Russell1-2/+2
module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option. For this version it'll simply give a warning, but it'll break next kernel version. Acked-by: Mauro Carvalho Chehab <mchehab@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2012-01-12i2c: Fix error value returned by several bus driversJean Delvare1-1/+5
When adding checks for ACPI resource conflicts to many bus drivers, not enough attention was paid to the error paths, and for several drivers this causes 0 to be returned on error in some cases.

2008-07-15i2c: Check for ACPI resource conflictsJean Delvare1-0/+6
Check for ACPI resource conflicts in i2c bus drivers. I've included all recent SMBus master drivers for PC hardware. I've voluntarily left out: * Drivers that don't run on PCs: they can't conflict with ACPI. * Bit-banged bus device drivers: it's very unlikely that ACPI would deal with such buses.

2008-07-15i2c: Let bus drivers add SPD to their classJean Delvare1-1/+1
Let general purpose I2C/SMBus bus drivers add SPD to their class. Once this is done, we will be able to tell the eeprom driver to only probe for SPD EEPROMs and similar on these buses. Note that I took a conservative approach here, adding I2C_CLASS_SPD to many drivers that have no idea whether they can host SPD EEPROMs or not. This is to make sure that the eeprom driver doesn't stop probing buses where SPD EEPROMs or equivalent live. So, bus driver maintainers and users should feel free to remove the SPD class from drivers those buses never have SPD EEPROMs or they don't want the eeprom driver to bind to them. Likewise, feel free to add the SPD class to any bus driver I might have missed. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2008-07-15i2c: Consistently reject unsupported transactionsJean Delvare1-3/+2

2008-07-15i2c: Bus drivers return -Errno not -1David Brownell1-21/+26
Tighten error paths used by various i2c adapters (mostly x86) so they return real fault/errno codes instead of a "-1" (which is most often interpreted as "-EPERM"). Build tested, with eyeball review. One minor initial goal is to have adapters consistently return the code "-ENXIO" when addressing a device doesn't get an ACK response, at least in the probe paths where they are already good at stifling related logspam.

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!
