After thinking about it more, I think it is very likely that removing
all the overlays is the correct thing to do in the kexec use-case. When
kexec-ing, it makes sense that we'd want the exact same behaviour from
the kexec'ed kernel. That means we want the device drivers to do the
same thing including loading whatever overlays they depend on.
Are the device drivers loading the overlays?
That sounds a bit backwards to me.
Depends on what you mean with 'device driver'. In our case we have a driver
dedicated to handle card status. Quite similar to what the connector subsystem
does but with significantly more functionality (including devicetree overlay
management).
