This adds support for the BL808 watchdog. The implementation has a resolution of 1 second and the timeout range can be set from 1 - 2^14 seconds. To test with busybox's watchdog:

Hi, your patch seems to have other files. Can you clean up?

create mode 100644 drivers/watchdog/max_timeout create mode 100644 drivers/watchdog/timeout_max

Must have happened when I rebased after seeing you went to RC6. On it.

Just a FYI, we mostly working off @arm000 tree atm in case you are not aware. https://github.com/arm000/linux-bl808

I also sent a PR directly to that repo, and could see some team interactions, but I was a little confused by the branch naming conventions. And I'm a little confused by where your linux patch files come and how they're generated.

In any case I've cleaned up the PR.

Patches are mainly coming from dyn's tree but a few extra ones relating to opensbi support etc. if you can, join the #ox64-nutcracker channel on the pin64 community. Most of us are cooridinating there.

Closing. Once this is merged upstream and this project's linux is updated, I'll open a minor PR that just updates the linux_defconfig to add the watchdog.
