^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) Description
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) -----------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) This driver implements support for the Microchip TC654 and TC655.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) The TC654 uses the 2-wire interface compatible with the SMBUS 2.0
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) specification. The TC654 has two (2) inputs for measuring fan RPM and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) one (1) PWM output which can be used for fan control.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) Configuration Notes
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) -------------------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) Ordinarily the pwm1_mode ABI is used for controlling the pwm output
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) mode.  However, for this chip the output is always pwm, and the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) pwm1_mode determines if the pwm output is controlled via the pwm1 value
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) or via the Vin analog input.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32) Setting pwm1_mode to 1 will cause the pwm output to be driven based on
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33) the pwm1 value. Setting pwm1_mode to 0 will cause the pwm output to be
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34) driven based on the Vin input.
