Jia Jie Ho Nov. 30, 2022, 5:52 a.m. UTC
This patch series adds kernel driver support for Starfive crypto engine.
The engine supports hardware acceleration for HMAC/hash functions,
AES block cipher operations and RSA. The first patch adds basic driver
for device probe and DMA init. The subsequent patches adds supported
crypto primitives to the driver which include hash functions, AES and
RSA. Patch 5 adds documentation to describe device tree bindings and the
last patch adds device node to VisionFive 2 dts.

The driver has been tested with crypto selftest and additional test.

This patch series depends on the following patches:
https://patchwork.kernel.org/project/linux-riscv/cover/20221118010627.70576-1-hal.feng@starfivetech.com/
https://patchwork.kernel.org/project/linux-riscv/cover/20221118011714.70877-1-hal.feng@starfivetech.com/

Node names should be generic.
https://devicetree-specification.readthedocs.io/en/latest/chapter2-devicetree-basics.html#generic-names-recommendation

No underscores in node names.

Does not look like you tested the DTS against bindings. Please run `make
dtbs_check` (see Documentation/devicetree/bindings/writing-schema.rst
for instructions).

Hi Conor, 
Yes, Huan Feng co-developed this driver.

These drivers are always enabled. 
Is everything ok with the dts node entries?
Thank you for spending time reviewing and providing suggestions for this patch.

I'll fix the node name and run dtbs_check for the revised series.
Really appreciate your time and effort reviewing this patch.

In that case, the SoB block should look like:

Co-developed-by: Huan Feng <huan.feng@starfivetech.com>
Signed-off-by: Huan Feng <huan.feng@starfivetech.com>
Signed-off-by: Jia Jie Ho <jiajie.ho@starfivetech.com>

Similarly for any other patches they may have co-developed :)

If the hardware is always present, why not drop the "disabled" in
jh7110.dtsi & these two entries marking them as "okay" in the .dts?
