2013-01-25hwmon: Replace SENSORS_LIMIT with clamp_valGuenter Roeck
SENSORS_LIMIT and the generic clamp_val have the same functionality, and clamp_val is more efficient. This patch reduces text size by 9052 bytes and bss size by 11624 bytes for x86_64 builds.

2012-12-05hwmon: (ads7828) add support for ADS7830Guillaume Roguez
The ADS7830 device is almost the same as the ADS7828, except that it does 8-bit sampling, instead of 12-bit. This patch extends the ads7828 driver to support this chip.

2012-12-05hwmon: (ads7828) driver cleanupVivien Didelot
As there is no reliable way to identify the chip, it is preferable to remove the detect callback, to avoid misdetection. Module parameters are not worth it here, so let's get rid of them and add an ads7828_platform_data structure instead. Clean the code by removing unused macros, fixing coding style issues, avoiding function prototypes and using convenient macros such as module_i2c_driver().

Convert to use devm_ functions to reduce code size and simplify the code. Signed-off-by: Guenter Roeck <linux@roeck-us.net>

2012-01-13module_param: make bool parameters really bool (drivers & misc)Rusty Russell
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>
2011-11-04hwmon: Use i2c_smbus_{read,write}_word_swappedJean Delvare
Make use of the new i2c_smbus_{read,write}_word_swapped functions. This makes the driver code more compact and readable. It also ensures proper error handling.

2011-01-12hwmon: (ads7828) Update email contact detailsSteven Hardy
Trivial patch updating my email contact details due to change of employer, and because I no longer have access to the previously used domain. Unfortunately I also no longer have access to any ads7828 hardware, but am happy to support/maintain the driver if others are able to test changes.

2009-12-14i2c: Drop I2C_CLIENT_INSMOD_1Jean Delvare
This macro simply declares an enum, so drivers might as well declare it themselves. Signed-off-by: Jean Delvare <khali@linux-fr.org> Tested-by: Wolfram Sang <w.sang@pengutronix.de>
2009-12-14i2c: Get rid of struct i2c_client_address_dataJean Delvare
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>
2009-12-14i2c: Drop the kind parameter from detect callbacksJean Delvare
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>
2009-12-09hwmon: Clean up detect functionsJean Delvare
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: Corentin Labbe <corentin.labbe@geomatys.fr> Cc: "Mark M.
