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. 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] Quan Nguyen (4): dt-bindings: mfd: Add bindings for Ampere Altra SMPro drivers mfd: simple-mfd-i2c: Adds Ampere's Altra SMpro support hwmon: smpro: Add Ampere's Altra smpro-hwmon driver docs: hwmon: (smpro-hwmon) Add documentation .../bindings/hwmon/ampere,ac01-hwmon.yaml | 27 + .../devicetree/bindings/mfd/ampere,smpro.yaml | 82 +++ Documentation/hwmon/index.rst | 1 + Documentation/hwmon/smpro-hwmon.rst | 101 ++++ drivers/hwmon/Kconfig | 8 + drivers/hwmon/Makefile | 1 + drivers/hwmon/smpro-hwmon.c | 494 ++++++++++++++++++ drivers/mfd/Kconfig | 10 + drivers/mfd/simple-mfd-i2c.c | 6 + 9 files changed, 730 insertions(+) create mode 100644 Documentation/devicetree/bindings/hwmon/ampere,ac01-hwmon.yaml create mode 100644 Documentation/devicetree/bindings/mfd/ampere,smpro.yaml create mode 100644 Documentation/hwmon/smpro-hwmon.rst create mode 100644 drivers/hwmon/smpro-hwmon.c -- 2.28.0
