You named the file quite generic "atmel,tdes" or "atmel,aes", but > what if something newer comes for at91? Maybe name it instead > "atmel,at91sam9-aes"? > For historical reasons, the atmel-{aes,tdes,sha} drivers use their own fixed compatible. The differentiation between the versions of the same IP and their capabilities is done at run-time, by interrogating a version register. Thus I expect that no new compatible will be added for neither of these IPs. Cheers, ta > Best regards, > Krzysztof
