A more descriptive commit log would be welcome here, for example
containing on which SoC this driver can be used, and on which it was
tested.

This is the third attempt at that driver, and you can find the previous
versions here:
https://patchwork.kernel.org/project/linux-arm-kernel/cover/20200210170143.20007-1-nborisov@xxxxxxxx/
https://lore.kernel.org/patchwork/patch/706512/

Most of the comments on those series still apply to yours.

Most importantly, this hwspinlock is used to synchronize the ARM cores
and the ARISC. How did you test this driver?

Thanks!
Maxime
