* i2c/chips: Remove deprecated pcf8574 driverWolfram Sang2009-09-18
| | | | | | | | | | The pcf8574 driver in drivers/i2c/chips which just exports its register to sysfs is superseded by drivers/gpio/pcf857x.c which properly uses the gpiolib. As this driver has been deprecated for more than a year, finally remove it.

* i2c: Convert the pcf8574 driver to a new-style i2c driverJean Delvare2008-07-16
| | | | | | | | | | | | | | The new-style pcf8574 driver implements the optional detect() callback to cover the use cases of the legacy driver. Warning: users will now have to use the force module parameter to get the driver to attach to their device. That's not a bad thing as these devices can't be detected anyway. Note that this doesn't change the fact that this driver is deprecated in favor of gpio/pcf857x. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* i2c/pcf8574: No arbitrary initializationJean Delvare2007-10-13
| | | | | | | | Do not initialize the PCF8574 with an arbitrary value. Users will have to write the initial value to sysfs themselves. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Aurelien Jarno <aurelien@aurel32.net>
