Bay Trail-I PWM Control in Windows

Hello,

       I would like to understand if there are any drivers or libraries being released for the Bay Trail-I's SIO PWM controller for Windows 8 OS (64 and 32 bits).

       Currently the only drivers I am able to find for the Bay Tail-I SIO ports are HSUART, GPIO, I2C & SPI.

       Any help or pointer is appreciated.

       Thank you.

Regards,

Tai
