2017-08-13hwmon: (ads1015) Convert to using %pOF instead of full_nameRob Herring1-8/+6
Now that we have a custom printf format specifier, convert users of full_name to use %pOF instead. This is preparation to remove storing of the full path string for each node.

2017-06-11hwmon: (ads1015) move header file out of I2C realmWolfram Sang1-1/+1
include/linux/i2c is not for client devices. Move the header file to a more appropriate location. Signed-off-by: Wolfram Sang <wsa@the-dreams.de> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2017-04-02hwmon: (ads1015) Add OF device ID tableJavier Martinez Canillas1-1/+21
The driver doesn't have a struct of_device_id table but supported devices are registered via Device Trees. This is working on the assumption that a I2C device registered via OF will always match a legacy I2C device ID and that the MODALIAS reported will always be of the form i2c:<device>. But this could change in the future so the correct approach is to have an OF device ID table if the devices are registered via OF.

2016-02-18hwmon: (ads1015) Handle negative conversion values correctlyPeter Rosin1-1/+1
Make the divisor signed as DIV_ROUND_CLOSEST is undefined for negative dividends when the divisor is unsigned. Signed-off-by: Peter Rosin <peda@axentia.se> Cc: stable@vger.kernel.org Signed-off-by: Guenter Roeck <linux@roeck-us.net>

2014-08-05hwmon: (ads1015) Fix out-of-bounds array accessAxel Lin1-0/+2
Current code uses data_rate as array index in ads1015_read_adc() and uses pga as array index in ads1015_reg_to_mv, so we must make sure both data_rate and pga settings are in valid value range. Return -EINVAL if the setting is out-of-range. Signed-off-by: Axel Lin <axel.lin@ingics.com> Cc: stable@vger.kernel.org Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2014-07-29hwmon: (ads1015) Fix off-by-one for valid channel index checkingAxel Lin1-1/+1
Current code uses channel as array index, so the valid channel value is 0 .. ADS1015_CHANNELS - 1. Signed-off-by: Axel Lin <axel.lin@ingics.com> Cc: stable@vger.kernel.org Signed-off-by: Guenter Roeck <linux@roeck-us.net>

2012-03-18hwmon: convert drivers/hwmon/* to use module_i2c_driver()Axel Lin1-12/+1
