Hi Herbert, We've been working on getting this driver code upstreamed into drivers/misc since the end of last year but things stalled a bit on our end. However, we are still interested in getting our submission approved and would please like your assistance and feedback on this. The driver code for the hardware is straightforward and does not contain any cryptographic components as the cryptography is handled within the hardware's secure boundary. We have no plans to use the linux kernel crypto APIs as our customers require compliance to the FIPS 140 standard or the eIDAS regulations. Here is a link to the previous email I sent, which also contains more background links to our initial discussions with Greg and the actual patch. https://marc.info/?l=linux-crypto-vger&m=157918288423889&w=2 Can I please have your approval on this submission?
