Replace by more specific (c files)

2026-07-03T05:38:17+00:00

Replace the #include of by the more specific where applicable. For most cases the include can be dropped completely, only a few drivers need one or two headers added.

hwmon: Use named initializers for arrays of i2c_device_data

2026-06-09T15:22:59+00:00

While being less compact, using named initializers allows to more easily see which members of the structs are assigned which value without having to lookup the declaration of the struct. And it's also more robust against changes to the struct definition. The mentioned robustness is relevant for a planned change to struct i2c_device_id that replaces .driver_data by an anonymous union. While touching all these arrays, unify indention and usage of commas. This patch doesn't modify the compiled arrays, only their representation in source form benefits. The former was confirmed with x86 and arm64 builds.

hwmon: (tmp102) Use device_property_read_string API

2026-06-09T15:22:59+00:00

Replace of_property_read_string() with the preferded device_property_read_string() in the probe function to read the device label property, improving the driver compatibility since this method is not limited to Device Tree only. Also drop the now unnecessary __maybe_unused from tmp102_of_match.

hwmon: (tmp102) add support for update interval

2026-04-03T18:10:05+00:00

Since the sensor supports different sampling intervals via bits CR0 and CR1 from the CONFIG register, add support in order for the conversion rate to be changed from user space. Default is 4 conv/sec. Signed-off-by: Flaviu Nistor Link: https://lore.kernel.org/r/20260403140654.10368-1-flaviu.nistor@gmail.com Signed-off-by: Guenter Roeck

hwmon: (tmp102) Drop unnecessary include files

2025-10-15T18:02:43+00:00

The driver does not perform any locking and does not create sysfs attributes. Drop the unnecessary include files. Signed-off-by: Guenter Roeck

hwmon: tmp102: Add support for label

2025-09-07T23:33:48+00:00

Add support for label sysfs attribute similar to other hwmon devices. This is particularly useful for systems with multiple sensors on the same board, where identifying individual sensors is much easier since labels can be defined via device tree.

hwmon: Drop explicit initialization of struct i2c_device_id::driver_data to 0

2024-05-01T14:47:49+00:00

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.

hwmon: (tmp102) Use maple tree register cache

2023-06-10T14:37:02+00:00

The tmp102 is only capable of performing single register read and write operations which means it gains no advantage from using a rbtree register cache, convert it to using the more modern maple tree register cache instead. This should be more efficient. Signed-off-by: Mark Brown Link: https://lore.kernel.org/r/20230609-hwmon-maple-v1-3-8edacce86b28@kernel.org Signed-off-by: Guenter Roeck

hwmon: Switch i2c drivers back to use .probe()

2023-06-08T13:41:17+00:00

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.
