Message

Hello

This patch serie adds support for the second version of Allwinner Security System.
The first generation of the Security System is already handled by the sun4i-ss driver.
Due to major change, the first driver cannot handle the second one.
This new Security System is present on A80 and A83T SoCs.

For the moment, the driver support only DES3/AES in ECB/CBC mode.
Patchs for CTR/CTS, RSA and RNGs will came later.

This serie is tested with CRYPTO_MANAGER_EXTRA_TESTS
and tested on:
sun8i-a83t-bananapi-m3
sun9i-a80-cubieboard4

This serie is based on top of the "crypto: add sun8i-ce driver for
Allwinner crypto engine" serie.

Regards

Changes since v1:
- fixed uninitialized err in sun8i_ss_allocate_chanlist
- Added missing commit description on DT Documentation patch
