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@suse.com/ 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
