Yes, the config changed between 4.5 and 4.11. You can see the config
here ->
https://git.centos.org/blob/sig-altarch!kernel.git/sig-altarch7-aarch64/SOURCES!kernel-alt-4.11.0-aarch64.config

It is the upstream (RedHat provided) config with no modifications.

Unfortunately I cannot. Much of the hardware is provided under NDA.
