hwmon: (max1668) Convert to use with_info hwmon API

2024-07-31T17:43:53+00:00

Convert to use with_info API to simplify the code and to reduce its size. This patch reduces object file size by approximately 25%. Reviewed-by: Tzung-Bi Shih Signed-off-by: Guenter Roeck

hwmon: (max1668) Replace chip type with number of channels

2024-07-31T17:43:53+00:00

The only difference between supported chips is the number of channels. Drop enum chips and list the number of channels in struct i2c_device_id directly. Reviewed-by: Tzung-Bi Shih Signed-off-by: Guenter Roeck

hwmon: (max1668) Convert to use regmap

2024-07-31T17:43:53+00:00

Use regmap for caching to simplify the code and to hide read/write register address differences. Reviewed-by: Tzung-Bi Shih Signed-off-by: Guenter Roeck

hwmon: (max1668) Remove use of i2c_match_id()

2024-06-08T23:07:33+00:00

The function i2c_match_id() is used to fetch the matching ID from the i2c_device_id table. This is often used to then retrieve the matching driver_data. This can be done in one step with the helper i2c_get_match_data(). This helper has a couple other benefits: * It doesn't need the i2c_device_id passed in so we do not need to have that forward declared, allowing us to remove those or move the i2c_device_id table down to its more natural spot with the other module info. * It also checks for device match data, which allows for OF and ACPI based probing. That means we do not have to manually check those first and can remove those checks.

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: move from strlcpy with unused retval to strscpy

Follow the advice of the below link and prefer 'strscpy' in this subsystem. Conversion is 1:1 because the return value is not used. Generated by a coccinelle script.

hwmon: cleanup non-bool "valid" data fields

2021-10-12T14:22:41+00:00

We have bool so use it consistently in all the drivers. The following Coccinelle script was used: @@ identifier T; type t = { char, int }; @@ struct T { ... - t valid; + bool valid; ... } @@ identifier v; @@ ( - v->valid = 0 + v->valid = false | - v->valid = 1 + v->valid = true ) followed by sed to fixup the comments: sed '/bool valid;/{s/!=0/true/;s/zero/false/}' Few whitespace changes were fixed manually. All modified drivers were compile-tested.

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.
