2009-05-05i2c: Timeouts off by 1Roel Kluin
with while (timeout++ < MAX_TIMEOUT); timeout reaches MAX_TIMEOUT + 1 after the loop, so the tests below are off by one. Signed-off-by: Roel Kluin <roel.kluin@gmail.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2008-07-14i2c: Check for ACPI resource conflictsJean Delvare
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.

2008-07-14i2c: Let bus drivers add SPD to their classJean Delvare
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>
