hwmon: (pmbus/max16601) Add support for new revisions of MAX16508 New revisions of MAX16508 report MAX16508.xx or MAX16508y.xx as device ID, but are functionally similar to MAX16508. Add support for those chip variants. Cc: Vlad Sytchenko <vsytch@google.com> Cc: Steve Foreman <foremans@google.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

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/max16601) Add support for MAX16508 MAX16508 is quite similar to MAX16601, except that it does not support the DEFAULT_NUM_POP register and we thus can not dynamically determine the number of populated phases.

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.
