2024-05-01hwmon: Drop explicit initialization of struct i2c_device_id::driver_data to 0Uwe Kleine-König
These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own.

2023-06-08hwmon: Switch i2c drivers back to use .probe()Uwe Kleine-König
After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

2022-09-25hwmon: (ltc2947) Switch to EXPORT_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr()Jonathan Cameron
These newer PM macros allow the compiler to see what code it can remove if !CONFIG_PM_SLEEP. This allows the removal of __maybe_unused markings whilst achieving the same result. In this case it also lets the structure itself be removed.

2020-09-23hwmon: (ltc2947) use simple i2c probeStephen Kitt
This driver doesn't use the id information provided by the old i2c probe function, so it can trivially be converted to the simple ("probe_new") form.

2019-11-06hwmon: Add support for ltc2947Nuno Sá
The ltc2947 is a high precision power and energy monitor with an internal sense resistor supporting up to +/- 30A. Three internal no Latency ADCs ensure accurate measurement of voltage and current, while high-bandwidth analog multiplication of voltage and current provides accurate power measurement in a wide range of applications. Internal or external clocking options enable precise charge and energy measurements.
