The ASPEED AST2400/2500 PWM controller supports 8 PWM output ports.
The ASPEED AST2400/2500 Fan tach controller supports 16 tachometer
inputs.
The device driver matches on the device tree node. The configuration
values are read from the device tree and written to the respective
registers.
The driver provides a sysfs entries through which the user can
configure the duty-cycle value (ranging from 0 to 100 percent) and read
the fan tach rpm value.

Currently there is no method for setting the channel
value from the DTS file. When, the driver uses a dts
file to initialize the driver platform_data is not set.
As a result channel variable may not be set correctly.

Without the channel variable set correctly, some of the
sensors will not be initialized correctly. For example
temp3 sensor sysfs entries.

This implements the schema agreed with the device tree
binding document.

The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.

But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.
