TPM Device Driver

Dear Kylie,

I just tested the new TIS-driver (from todays CVS) with the Infineon 1.2-TPM and
Kernel 2.6.14-rc3.

The module recognizes the chip:

Oct  7 16:29:55 TPM tpm_tis 00:0c: Infineon 1.2 TPM (device-id 0xB, rev-id 16)

but there are send/receive errors:

Oct  7 16:30:07 TPM tpm_tis 00:0c: tpm_transmit: tpm_recv: error 4294967291

I am going to have a deeper look into the source code and will try to find
a solution for that.

Best regards!

Marcel Selhorst
