Hi Miquel, Simon,
Is there any specific reason why the new tpm2_tis_spi_xfer doesn't support full duplex? It seems we did some work in parallel but you sent the patches earlier. Is that codes tested against an existing TPM v2? I have a working implementation what runs on SLB9670 including full duplex.
What do you mean exactly?
I don't think the TPM2 protocol makes real use of full-duplex unless for the wait state between the host command and the actual xfer.
