Hello
The rockchip crypto driver is broken and do not pass self-tests.
This serie's goal is to permit to become usable and pass self-tests.
This serie also adds support for 2 more SoCs.
This whole serie is tested on a rk3328-rock64, rk3288-miqi with selftests (with
CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y)
The serie is also tested on a rk3399 by Hugh Cole-Baker
<[email protected]> and Igor Velkov <[email protected]>, Thanks to them for
testing.
Regards
Changes since v1:
- select CRYPTO_ENGINE
- forgot to free fallbacks TFMs
- fixed kernel test robots warning
- add the PM patch
Changes since v2:
- Added DMA clock back to 3288 since it dont work without it
- fallback needed to select CBC and ECB configs
- Added support for rk3399
- Added more patch (style, read_poll_timeout)
Changes since v3:
- full rewrite of support for RK3399
- splited dt-binding patch in two

2.35.1
The rk3399 has a crypto IP handled by the rk3288 crypto driver so adds a
node for it.

crypto_info->dev is not yet set, so use pdev->dev instead.
