Description
|
|
-----------
|
|
This driver implements support for the Microchip TC654 and TC655.
|
|
|
|
The TC654 uses the 2-wire interface compatible with the SMBUS 2.0
|
|
specification. The TC654 has two (2) inputs for measuring fan RPM and
|
|
one (1) PWM output which can be used for fan control.
|
|
|
|
Configuration Notes
|
|
-------------------
|
|
Ordinarily the pwm1_mode ABI is used for controlling the pwm output
|
|
mode. However, for this chip the output is always pwm, and the
|
|
pwm1_mode determines if the pwm output is controlled via the pwm1 value
|
|
or via the Vin analog input.
|
|
|
|
|
|
Setting pwm1_mode to 1 will cause the pwm output to be driven based on
|
|
the pwm1 value. Setting pwm1_mode to 0 will cause the pwm output to be
|
|
driven based on the Vin input.
