ASCON-128, ASCON-128a, ASCON-HASH and ASCON-HASHA would fit into the PSA Certified API, with just the definition of some key types (for the AEAD) and algorithm Ids needed.

Are you going to define such constants for the PSA Certified API?

Ascon is a family of authenticated encryption and hashing algorithms designed to be lightweight and easy to implement, even with added countermeasures against side-channel attacks. Ascon has been selected as new standard for lightweight cryptography in the NIST Lightweight Cryptography competition (2019–2023). Ascon has also been selected as the primary choice for lightweight authenticated encryption in the final portfolio of the CAESAR competition (2014–2019).
