hwmon: Switch i2c drivers back to use .probe() 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: (pmbus) shrink code and remove pmbus_do_remove() The only action currently performed in pmbus_do_remove() is removing the debugfs hierarchy. We can schedule a devm action at probe time and remove pmbus_do_remove() entirely from all pmbus drivers.

hwmon (pmbus) use simple i2c probe function pmbus_do_probe doesn't use the id information provided in its second argument, so this can be removed, which then allows using the single-parameter i2c probe function ("probe_new") for probes. 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); * configured v. probed comparisons are performed by comparing the configured name to the detected name, instead of the ids; this involves strcmp but is still cheaper than comparing all the device names when scanning the tables; * anything else is handled by calling i2c_match_id() with the same level of error-handling (if any) as before. Additionally, the mismatch message in the ltc2978 driver is adjusted so that it no longer assumes that the driver_data is an index into ltc2978_id.

hwmon: (pmbus/core) Add support for vid mode detection per page bases Add support for VID protocol detection per page bases, instead of detecting it based on "PMBU_VOUT" readout from page 0 for all the pages supported by particular device. The reason that some devices allows to configure different VID modes per page within the same device. Patch modifies the field "vrm_version" within the structure "pmbus_driver_info" to be per page array.

hwmon: (pmbus) Add support for MAX20751 MAX20751 is a multiphase power controller with internal buck converter. It uses VR12.0 to report the output voltage. This requires an explicit driver, since the VR version can not be auto-detected. The chip supports a manufacturer specific command to fine-tune the output voltage. This command is not currently supported. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
