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.

hwmon: tmp102: constify pointers to hwmon_channel_info

hwmon: (tmp102) Switch to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr()

2022-09-25T21:22:12+00:00

These newer PM macros allow the compiler to see what code it can remove if !CONFIG_PM_SLEEP. This allows the removal of #ifdef guards whilst achieving the same result.

hwmon: use simple i2c probe function

2020-09-23T16:42:39+00:00

Many hwmon drivers don't use the id information provided by the old i2c probe function, and the remainder can easily be adapted to the new form ("probe_new") by calling i2c_match_id explicitly. This avoids scanning the identifier tables during probes. Drivers which didn't use the id are converted as-is; drivers which did are modified as follows: * if the information in i2c_client is sufficient, that's used instead (client->name); * anything else is handled by calling i2c_match_id() with the same level of error-handling (if any) as before. A few drivers aren't included in this patch because they have a different set of maintainers. They will be covered by other patches.

hwmon: (tmp102) Use HWMON_CHANNEL_INFO macro

2019-04-16T00:19:53+00:00

The HWMON_CHANNEL_INFO macro simplifies the code, reduces the likelihood of errors, and makes the code easier to read. The conversion was done automatically with coccinelle. The semantic patch used to make this change is as follows. @r@ initializer list elements; identifier i; @@ -u32 i[] = { - elements, - 0 -}; @s@ identifier r.i,j,ty; @@ -struct hwmon_channel_info j = { - .type = ty, - .config = i, -}; @script:ocaml t@ ty << s.ty; elements << r.elements; shorter; elems; @@ shorter := make_ident (List.hd(List.rev (Str.split (Str.regexp "_") ty))); elems := make_ident (String.concat "," (List.map (fun x -> Printf.sprintf "\n\t\t\t %s" x) (Str.split (Str.regexp " , ") elements))) @@ identifier s.j,t.shorter; identifier t.elems; @@ - &j + HWMON_CHANNEL_INFO(shorter,elems) This patch does not introduce functional changes.
