* hwmon: (ina209) Use permission specific SENSOR[_DEVICE]_ATTR variantsGuenter Roeck2019-02-181-86/+65
| | | | | | | | | | | | | | | | Use SENSOR[_DEVICE]_ATTR[_2]_{RO,RW,WO} to simplify the source code, to improve readability, and to reduce the chance of inconsistencies. Also replace any remaining S_<PERMS> in the driver with octal values. The conversion was done automatically with coccinelle. The semantic patches and the scripts used to generate this commit log are available at https://github.com/groeck/coccinelle-patches/hwmon/. This patch does not introduce functional changes. It was verified by compiling the old and new files and comparing text and data sizes. Signed-off-by: Guenter Roeck <linux@roeck-us.net>

| | | | | | | | | The shunt voltage and current registers are signed 16-bit values so handle them as such. Signed-off-by: Joe Schaack <jschaack@xes-inc.com> Reviewed-by: Aaron Sierra <asierra@xes-inc.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
* hwmon: (ina209) Add OF device ID tableJavier Martinez Canillas2017-04-021-0/+7
| | | | | | | | | | | | | 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.
