Kernel driver aspeed-g6-pwm-tach
=================================
Supported chips:
ASPEED AST2600
Authors:
<billy_tsai@aspeedtech.com>
Description:
------------
This driver implements support for ASPEED AST2600 Fan Tacho controller.
The controller supports up to 16 tachometer inputs.
The driver provides the following sensor accesses in sysfs:
=============== ======= ======================================================
fanX_input ro provide current fan rotation value in RPM as reported
by the fan to the device.
fanX_div rw Fan divisor: Supported value are power of 4 (1, 4, 16
64, ... 4194304)
The larger divisor, the less rpm accuracy and the less
affected by fan signal glitch.
=============== ======= ======================================================
