It might make sense for the cryptov1-rng driver (I haven't checked). For the cryptov2-rng driver, I looked at the RK3568 TRM (I can't find the RK3588 one), and from what I understand crypto and TRNG are two different devices, using different address spaces, clock, reset and interrupts. The vendor kernel uses two different drivers. Regards Aurelien -- Aurelien Jarno GPG: 4096R/1DDD8C9B aurelien@xxxxxxxxxxx http://www.aurel32.net
