2020-09-23hwmon (pmbus) use simple i2c probe functionStephen Kitt
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.

2019-04-15hwmon: (pmbus/ir38064) Add driver for Infineon IR38064 Voltage RegulatorMaxim Sloyko
Add the pmbus driver for the Infineon ir38064 voltage regulator. VOUT_MODE is not supported by the device. The driver fakes linear16 mode with exponent value -8. The device supports VOUT_PEAK, IOUT_PEAK, and TEMPERATURE_PEAK, however this driver does not enable them.
