As you point out in patch 1/8, PCIEASPM is protected by EXPERT.

Won't this prevent the driver from being built (or even showing up in
menuconfig) if EXPERT is not enabled?

Should we consider having a separate CONFIG item that is used to protect just
the PCI ASPM interfaces? And then we could split out the ath12k_pci_aspm
functions into a separate file that is conditionally built based upon that
config item?

Or am I too paranoid since everyone enables EXPERT?
