Hello!
This patchset expand the funcionality of the Amlogic
crypto driver by adding support for more SoC families:
AXG, G12A, G12B, SM1, A1, S4.
Also specify and enable crypto node in device tree
for reference Amlogic devices.
Tested on GXL, AXG, G12A/B, SM1, A1 and S4 devices via
custom tests [1] and tcrypt module.
---
Changes V1 -> V2 [2]:
- Rebased over linux-next.
- Adjusted device tree bindings description.
- A1 and S4 dts use their own compatible, which is a G12 fallback.
Changes V2 -> V3 [3]:
- Fix errors in dt-bindings and device tree.
- Add new field in platform data, which determines
whether clock controller should be used for crypto IP.
- Place back MODULE_DEVICE_TABLE.
- Correct commit messages.
Changes V3 -> V4 [4]:
- Update dt-bindings as per Krzysztof Kozlowski comments.
- Fix bisection: get rid of compiler errors in some patches.
Changes V4 -> V5 [5]:
- Tested on GXL board:
1. Fix panic detected by Corentin Labbe [6].
2. Disable hasher backend for GXL: in its current realization
is doesn't work. And there are no examples or docs in the
vendor SDK.
- Fix AES-CTR realization: legacy boards (gxl, g12, axg) requires
inversion of the keyiv at keys setup stage.
- A1 now uses its own compatible string.
- S4 uses A1 compatible as fallback.
- Code fixes based on comments Neil Atrmstrong and Rob Herring.
- Style fixes (set correct indentations)
Changes V5 -> V6 [7]:
- Fix DMA sync warning reported by Corentin Labbe [8].
- Remove CLK input from driver. Remove clk definition
and second interrput line from crypto node inside GXL dtsi.

This patch adds a crypto node declaration for Amlogic G12-series.
With the Amlogic crypto driver we can use HW implementation
of SHA1/224/256 and AES algo.
