hwmon: (ads7828) Use permission specific SENSOR[_DEVICE]_ATTR variants

2018-12-16T23:13:35Z

Use SENSOR[_DEVICE]_ATTR[_2]_{RO,RW,WO} to simplify the source code, to improve readbility, and to reduce the chance of inconsistencies. Also replace any remaining S_ 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

hwmon: (ads7828) Accept optional parameters from device tree

2017-04-02T14:01:53Z

Adding the ability for the ads7828 and ads7830 to use device tree to get optional parameters instead of using platform devices. This allows people using custom boards to also use the ads7828 in a non-default manner. Signed-off-by: Sam Povilus [groeck: Fixed whitespace errors in ads7828.txt] Signed-off-by: Guenter Roeck

hwmon: (ads7828) Add OF device ID table

2017-04-02T14:01:53Z

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:. 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.

hwmon: (ads7828) Enable internal reference

2016-04-19T13:30:28Z

On ads7828 the internal reference defaults to off upon power up. When using internal reference, it needs to be turned on and the voltage needs to settle before normal conversion cycle can be started. Hence perform a dummy read in the probe to enable the internal reference allowing the voltage to settle before performing a normal read. Without this fix, the first read from the ADC when using internal reference always returns incorrect data. Signed-off-by: Akshay Bhat Cc: stable@vger.kernel.org # v4.1+ Signed-off-by: Guenter Roeck

hwmon: (ads7828) Check return value of devm_regmap_init_i2c

2015-02-23T04:10:30Z

devm_regmap_init_i2c() can fail, thus add return value checking. Signed-off-by: Axel Lin Signed-off-by: Guenter Roeck

hwmon: (ads2828) Only keep data in device data structure if needed

2015-02-02T16:20:06Z

The variables diff_input, ext_vref, and vref_mv are only used in the probe function and therefore don't need to be kept in the device data structure. Reviewed-and-Tested-by: Robert Rosengren Signed-off-by: Guenter Roeck

hwmon: (ads2828) Convert to use regmap

2015-02-02T16:19:58Z

Simplify code and reduce code size by using regmap to access i2c registers. Reviewed-and-Tested-by: Robert Rosengren Signed-off-by: Guenter Roeck

hwmon: (ads7828) Convert to devm_hwmon_device_register_with_groups

2014-08-04T14:01:34Z

Use ATTRIBUTE_GROUPS macro and devm_hwmon_device_register_with_groups() to simplify the code a bit. Signed-off-by: Axel Lin Signed-off-by: Guenter Roeck

hwmon: use dev_get_platdata()

2013-08-12T05:10:39Z

Use the wrapper function for retrieving the platform data instead of accessing dev->platform_data directly. Signed-off-by: Jingoo Han Signed-off-by: Guenter Roeck

hwmon: Replace SENSORS_LIMIT with clamp_val

2013-01-26T05:03:54Z

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. Signed-off-by: Guenter Roeck Acked-by: George Joseph Acked-by: Jean Delvare
