Subject: [PATCH v4 0/4] Add Ampere's Altra SMPro hwmon driver
Date: Thu, 22 Apr 2021 16:08:39 +0700 [thread overview]
Message-ID: <20210422090843.4614-1-quan@os.amperecomputing.com> (raw)
This patch series adds support for Ampere SMpro hwmon driver. This
driver supports accessing various CPU sensors provided by the SMpro
co-processor including temperature, power, voltages, and current found
on Ampere Altra processor family.
The SMpro co-processor on Ampere Altra processor family is to monitor
and report various data included hwmon-related info, RAS errors, and
other miscellaneous information. This parent SMPro MFD driver creates
a single simple register map to be shared by all sub-devices and leave
all the specific to be handled by the child drivers.
v4:
+ Revised commit message [Quan]
+ Fixed build issue found by kernel test robot [Guenter]
+ Returned regmap_read() error code [Guenter]
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]
