* hwmon: Fix off-by-one kind valuesJean Delvare2010-03-151-2/+2
| | | | | | | | | | | | | | | | | commit dc71afe5ac7e8d049bb991330518e4c898a7d92e upstream. Recent changes on the I2C front have left off-by-one array indexes in 3 hwmon drivers. Fix them. Faulty commit: e5e9f44c2 i2c: Drop I2C_CLIENT_INSMOD_2 to 8 Reported-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Hans de Goede <hdegoede@redhat.com> Cc: Andre Prendel <andre.prendel@gmx.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* hwmon: (tmp421) Restore missing inputsJean Delvare2010-03-151-7/+7
| | | | | | | | | | | | | | commit 8d59582a867470a3e0c3eced4a01625ae8dc546b upstream. An off-by-one error caused some inputs to not be created by the driver when they should. TMP421 gets only one input instead of two, TMP422 gets two instead of three, etc. Fix the bug by listing explicitly the number of inputs each device has.

* hwmon: (tmp421) Fix temperature conversionsJean Delvare2010-03-151-2/+4
| | | | | | | | | | | | commit a44908d742a577fb5ccb9a8c082326d4cea234c2 upstream. The low bits of temperature registers are status bits, they must be masked out before converting the register values to temperatures.

* i2c: Drop I2C_CLIENT_INSMOD_2 to 8Jean Delvare2009-12-141-2/+1
| | | | | | | | | These macros simply declare an enum, so drivers might as well declare it themselves. This puts an end to the arbitrary limit of 8 chip types per i2c driver. Signed-off-by: Jean Delvare <khali@linux-fr.org> Tested-by: Wolfram Sang <w.sang@pengutronix.de>
* i2c: Get rid of struct i2c_client_address_dataJean Delvare2009-12-141-1/+1
| | | | | | | | | Struct i2c_client_address_data only contains one field at this point, which makes its usefulness questionable. Get rid of it and pass simple address lists around instead. Signed-off-by: Jean Delvare <khali@linux-fr.org> Tested-by: Wolfram Sang <w.sang@pengutronix.de>
* i2c: Drop the kind parameter from detect callbacksJean Delvare2009-12-141-1/+1
| | | | | | | | The "kind" parameter always has value -1, and nobody is using it any longer, so we can remove it. Signed-off-by: Jean Delvare <khali@linux-fr.org> Tested-by: Wolfram Sang <w.sang@pengutronix.de>
* hwmon: (tmp401/tmp421) Clean up detect functionsJean Delvare2009-12-091-24/+21
| | | | | | | As kind is now hard-coded to -1, there is room for code clean-ups. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Andre Prendel <andre.prendel@gmx.de>
* hwmon: Add driver for Texas Instruments TMP421/422/423 sensor chipsAndre Prendel2009-09-151-0/+347
Add support for Texas Instruments TMP421/422/423 temperature sensor IC. TI's TMP421/422/423 are I2C temperature sensor chips. These chips are similar to TI's TMP401/411 chips, but with reduced functionality (only temperature measurement). The chips have one local sensor and up to three (TMP423) remote sensors.
