commit bdb6cf9f6fe6d9af905ea34b7c4bb78ea601329e upstream.
The current sun4i-ss driver could generate data corruption when ciphering/deciphering.
It occurs randomly on end of handled data.
No root cause have been found and the only way to remove it is to replace
all spin_lock_bh by their irq counterparts.

commit 4f9ea86604e3ba64edd2817795798168fbb3c1a6 upstream.
sun4i-ss implementaton of md5/sha1 is via ahash algorithms.
Commit 8996eafdcbad ("crypto: ahash - ensure statesize is non-zero")
made impossible to load them without giving statesize. This patch
specifiy statesize for sha1 and md5.

The sun4i_ss_opti_poll function cipher data until the output miter have
a length of 0.
If the crypto API client, give more SGs than necessary this could result
in an infinite loop.
Fix it by checking for remaining bytes, just like sun4i_ss_cipher_poll().

On sun6i and later platforms, the reset control is split out of the
clock gates. Add support for an optional reset control.

Add support for the Security System included in Allwinner SoC A20.
The Security System is a hardware cryptographic accelerator that support:
- MD5 and SHA1 hash algorithms
- AES block cipher in CBC/ECB mode with 128/196/256bits keys.
- DES and 3DES block cipher in CBC/ECB mode
