2014-08-04hwmon: (tmp421) Drop FSF mailing addressGuenter Roeck1-4/+0
The FSF mailing address can and will change over time, so drop it. Signed-off-by: Guenter Roeck <[email protected]> Reviewed-by: Jean Delvare <[email protected]>
2014-08-04hwmon: (tmp421) Add support for TMP441 and TMP442Guenter Roeck1-4/+17
TMP441 and TMP442 are compatible to TMP421 and TMP422. Signed-off-by: Guenter Roeck <[email protected]> Reviewed-by: Jean Delvare <[email protected]>
2014-08-04hwmon: (tmp421) Strengthen detect functionGuenter Roeck1-0/+14
Not all supported chips support the entire I2C address range. Only accept specific chips at the addresses supported by that chip. Check for invalid values in conversion rate and status registers. Signed-off-by: Guenter Roeck <[email protected]> Reviewed-by: Jean Delvare <[email protected]>
2014-05-21hwmon: (tmp421) Convert to use devm_hwmon_device_register_with_groupsGuenter Roeck1-32/+15
Use devm_hwmon_device_register_with_groups API to attach attributes to hwmon device, simplify code, and reduce code size. Reviewed-by: Jean Delvare <[email protected]> Signed-off-by: Guenter Roeck <[email protected]>

Propagate return value obtained from i2c_smbus_read_byte_data() instead of hardcoding. Signed-off-by: Sachin Kamat <[email protected]> Cc: Andre Prendel <[email protected]> Signed-off-by: Guenter Roeck <[email protected]>

Convert to use devm_ functions to reduce code size and simplify the code. Signed-off-by: Guenter Roeck <[email protected]> Acked-by: Jean Delvare <[email protected]>
2012-03-18hwmon: convert drivers/hwmon/* to use module_i2c_driver()Axel Lin1-12/+1
This patch converts the drivers in drivers/hwmon/* to use the module_i2c_driver() macro which makes the code smaller and a bit simpler.

2010-10-28hwmon: I2C addresses are constantJean Delvare1-2/+2
We can mark normal_i2c const. Almost all drivers do that already, so fix the 3 remaining ones before they are used as (bad) examples for new drivers. Signed-off-by: Jean Delvare <[email protected]> Cc: George Joseph <[email protected]> Reviewed-by: Guenter Roeck <[email protected]>
2010-06-03i2c: Remove all i2c_set_clientdata(client, NULL) in driversWolfram Sang1-2/+0
I2C drivers can use the clientdata-pointer to point to private data. As I2C devices are not really unregistered, but merely detached from their driver, it used to be the drivers obligation to clear this pointer during remove() or a failed probe(). As a couple of drivers forgot to do this, it was agreed that it was cleaner if the i2c-core does this clearance when appropriate, as there is no guarantee for the lifetime of the clientdata-pointer after remove() anyhow. This feature was added to the core with commit e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers. As there is no need anymore to clear the clientdata-pointer, remove all current occurrences in the drivers to simplify the code and prevent confusion.

2010-03-05hwmon: Fix off-by-one kind valuesJean Delvare1-2/+2
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 <[email protected]> Signed-off-by: Jean Delvare <[email protected]> Cc: Hans de Goede <[email protected]> Cc: Andre Prendel <[email protected]> Cc: [email protected]
2010-03-05hwmon: (tmp421) Fix temperature conversionsJean Delvare1-2/+4
The low bits of temperature registers are status bits, they must be masked out before converting the register values to temperatures. Signed-off-by: Jean Delvare <[email protected]> Tested-by: Andre Prendel <[email protected]> Cc: [email protected]
2010-03-05hwmon: (tmp421) Restore missing inputsJean Delvare1-7/+7
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.

2009-12-14i2c: Drop I2C_CLIENT_INSMOD_2 to 8Jean Delvare1-2/+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 <[email protected]> Tested-by: Wolfram Sang <[email protected]>
2009-12-14i2c: Get rid of struct i2c_client_address_dataJean Delvare1-1/+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 <[email protected]> Tested-by: Wolfram Sang <[email protected]>
2009-12-14i2c: Drop the kind parameter from detect callbacksJean Delvare1-1/+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 <[email protected]> Tested-by: Wolfram Sang <[email protected]>
2009-12-09hwmon: (tmp401/tmp421) Clean up detect functionsJean Delvare1-24/+21
As kind is now hard-coded to -1, there is room for code clean-ups. Signed-off-by: Jean Delvare <[email protected]> Acked-by: Andre Prendel <[email protected]>
2009-09-15hwmon: Add driver for Texas Instruments TMP421/422/423 sensor chipsAndre Prendel1-0/+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.
