[SRU v2][F:linux-bluefield][Pull Request] Sync up gpio interrupt handling with upstreamed version

[Asmaa Mnebhi]

@Stefan Bader<mailto:stefan.bader at canonical.com>, please let me know if this pull requests works better for you.



I cloned a clean linux-bluefield repo :

git clone https://git.launchpad.net/~canonical-kernel/ubuntu/+source/linux-bluefield/+git/focal

And was able to revert each commit mentioned in the cover letter one by one. If this fails for you, I am going to need some guidance.



Thanks.
Asmaa

Subject: [SRU v2][F:linux-bluefield][Pull Request] Sync up gpio interrupt handling with upstreamed version



This pull request (20 commits) includes reverting 6 gpio-mlxbf2 commits in linux-bluefield. Then it cherry-picks the commits made to gpio-mlxbf2 in the linux master branch. commit c8382b7415913d30f22cdfc28badc5e5de812f45

introduces proper IRQ handling in the gpio-mlxbf2 driver.

On top of the above, there are 3 commits:

add the gpio-mlxbf2 driver version, remove a flag in i2c-mlxbf.c to remain in sync with the interrupt handling in other drivers, and create the pwr-mlxbf driver responsible for handling the low power mode and reset interrupts.
