it should depend on CONFIG_CRYPTO_DEV_ROCKCHIP as rockchip folder is not included without it

else i did some tests, but it does not seem that the offloader is used (requests stay at initial value after the bootup test)

i wonder about the last 3 lines in dmesg (fallback), seems i miss something for these.
