Subject: [PATCH v2 0/5] crypto: add gemini/sl3516 crypto driver

The gemini SL3516 SoC has a crypto IP.
This serie had support for it.

It was tested with CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y.
Furthermore, it survives hours and gigs of write/read to a luks2 using xts(ecb-aes-sl3516).

Performance is quite good.
On a luks2 partition (2To with bs=4096), a fsck comes from 14m26(without CE) to 8m48(with CE).
So it is really usefull.

With bs=512, the performance is similar with software.

Changes since v1:
- reworded dt-binding subject patch
- fixed build with CRYPTO_DEV_SL3516_DEBUG

Corentin Labbe (5):
  dt-bindings: crypto: Add documentation for sl3516-ce
  crypto: Add sl3516 crypto engine
  ARM: dts: gemini: add crypto node
  ARM: gemini_config: enable sl3516-ce crypto
  MAINTAINERS: add gemini crypto sl3516-ce
