[v3,00/20] Support more Amlogic SoC families in crypto driver

Message

Alexey Romanov Feb. 5, 2024, 3:55 p.m. UTC

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 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.
