co-processor including temperature, power, voltages, and current found
on Ampere Altra processor family.

v3:
  + Supported list of compatible string [Rob]
  + Introduced reg property in DT to specify reg offset [Rob]
  + Updated description and other minor changes in yaml file [Rob]
  + Handled negative temperature value [Guenter]
  + Returned -ENODEV if Manufacturer ID is wrong [Guenter]
  + Refactored smpro_read_string() and smpro_temp_read() [Guenter]
  + Removed smpro_write() function [Guenter]
  + Added minor refactor changes [Quan]

v2:
  + Used 'struct of_device_id's .data attribute [Lee Jones]
  + Removed "virtual" sensors [Guenter]
  + Fixed typo "mili" to "milli", "nanoWatt" to "microWatt" [Guenter]
  + Reported SOC_TDP as "Socket TDP" using max attributes [Guenter]
  + Clarified "highest" meaning in documentation [Guenter]
  + Corrected return error code when host is turn off [Guenter]
  + Reported MEM HOT Threshold for all DIMMs as temp*_crit [Guenter]
  + Removed license info as SPDX-License-Identifier existed [Guenter]
  + Added is_visible() support [Guenter]
  + Used HWMON_CHANNEL_INFO() macro and LABEL attributes [Guenter]
  + Made is_valid_id() return boolean [Guenter]
  + Returned -EPROBE_DEFER when smpro reg inaccessible [Guenter]
  + Removed unnecessary error message when dev register fail [Guenter]
  + Removed Socket TDP sensor [Quan]
  + Changed "ampere,ac01-smpro" to "ampere,smpro" [Quan]
  + Included sensor type and channel in labels [Quan]
  + Refactorized code to fix checkpatch.pl --strict complaint [Quan]
