platform/x86: lenovo-wmi-other: Add HWMON for fan reporting/tuning
Register an HWMON device for fan reporting/tuning according to Capability Data 00 (capdata00) and Fan Test Data (capdata_fan) provided by lenovo-wmi-capdata. The corresponding HWMON nodes are: - fanX_div: internal RPM divisor - fanX_input: current RPM - fanX_max: maximum RPM - fanX_min: minimum RPM - fanX_target: target RPM (tunable, 0=auto) Information from capdata00 and capdata_fan are used to control the visibility and constraints of HWMON attributes. Fan info from capdata00 is collected on bind, while fan info from capdata_fan is collected in a callback. Once all fan info is collected, register the HWMON device.

The LENOVO_CAPABILITY_DATA_00 interface provides various information that
|
||||
does not rely on the gamezone thermal mode.
|
||||
|
||||
The following HWMON attributes are implemented:
|
||||
- fanX_div: internal RPM divisor
|
||||
- fanX_input: current RPM
|
||||
- fanX_target: target RPM (tunable, 0=auto)
|
||||
|
||||
Due to the internal RPM divisor, the current/target RPMs are rounded down to
|
||||
its nearest multiple. The divisor itself is not necessary to be a power of two.
