+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.
