Removing a property without telling the user what to expect is a bad
idea and ABI breakage.

What's the general process to remove a property?

I guess we should do:
1) deprecate it in the first place and remove it from all upstream DT
2) wait some long enough days for expecting the stale of all old DTB
containing that property
3) remove the functionality of the deprecated property from the driver
but still leave some warning there
4) remove the left warning finally

And for the ABI breakage, we should add something in Documentation/ABI
/obsolete  or Documentation/ABI/removed ?

I don't know. Perhaps Rob can shed a light here.
But I would really OK with removal of some of such properties from
some drivers where it's more burden to keep them.

This property had deprecated about 8months ago.
I think that it was enough to keep this property for maintaining the compatibility.

I didn't remove this property without any alternative.

Yes

> > containing that property

Yes. How long that is depends on the platform. I think the minimum is 1 
release cycle. Some stable platforms are years. If there are other DT 
changes with new features everyone should want/need, then that can be a 
decision point.

Given this is a shared IP block it's harder to know, so you may need to 
err on the longer side.

I'd say add a warning in step 1 and combine 3 and 4.

It is only an ABI break if someone notices.
