Dear Jean, Rudolf and MDS

This is Chunhao.

I'm busy with another project about Winbond W83637HF Smart IO these days
As you know, besides the Hardware monitor function, Winbond W83637HF
contains the function of Smart Cards. What I need to implement is the
Cards function.

I'm using MUSCLE project ( and towitoko-2.0.7
Smart Card driver( as my reference
Generally, the smart card readers connect PC by Serial interface or usb.
But W83637HF does NOT use serial nor usb, it is embedded on
motherboard(PC client)
using LPC interface for communication.

So in traditional smart card readers driver such as towitoko, it just
has to
talk to a UART via a regular serial port interface. but in my driver, I
will have
to deal with all the Input/Output, control registers, etc.

So my question is:
Do you know any source code on Linux(or Smart Card drivers) which can be
good reference to me when I implementing my low level function?
Is there any bus or chip driver contains such function in lm_sensors?

You know, I have few experience in Smart Card driver, this is the first
for me to write Smart Card driver.:-)

Best Regards
