Sorry, I had completely forgotten about the first patch from the series.
With that applied, it continues:

        ccree e6601000.crypto: ARM CryptoCell 630P Driver: HW version
0x00000000, Driver version 4.0
        ccree e6601000.crypto: Cache params previous: 0x00000777
        ccree e6601000.crypto: Cache params current: 0x00000000
(expect: 0x00000000)
        alg: No test for cts1(cbc(aes)) (cts1-cbc-aes-ccree)
        alg: No test for authenc(xcbc(aes),cbc(aes))
        alg: No test for authenc(xcbc(aes),rfc3686(ctr(aes)))
        ccree e6601000.crypto: ARM ccree device initialized

Is HW version 0x00000000 expected?

is there an easy way to test proper operation?
I enabled CONFIG_CRYPT_TEST, and did insmod tcrypt.ko, but I mostly see
"Failed to load transform" messages.
