[PATCH v3 0/3] add AES support for Exynos5433

[PATCH v3 0/3] add AES support for Exynos5433

[Kamil Konieczny]

Add slimSSS node to DT and crypto AES support for Exynos5433. Tested on
Exynos5433 board with crypto run-time self tests and with tcrypt with
command insmod tcrypt.ko mode=500 sec=1

Changes since v2:
- address Corentine Labbe note: add "const" to char* in declaration of
  struct samsung_aes_variant

Changes since v1:
- address Krzysztof Kozlowski review: add missing comma in struct
  definition, add goto for error code path, correct indentation,
  in documentation add that Exynos5433 has both slimSSS and SSS IPs.

Before picking this up, bindings have to be accepted and I see
discussion is still ongoing (no Ack from Rob yet). Anyway this depends
on header file with clock ID, so it will have to wait for next cycle.

I will pick it up for v5.2, after v5.1 merge window.

Best regards,
Krzysztof
