If ARCH_QCOM is enabled when building arm_smmu_v3,
This has nothing to do with SMMUv3, though?
a dependency on
qcom-scm is added, which currently cannot be disabled. Add a prompt to
ARM_SMMU_QCOM to allow disabling this dependency.
Why is that an issue - what problem arises from having the SCM driver
enabled? AFAICS it's also selected by plenty of other drivers including
pretty fundamental ones like pinctrl. If it is somehow important to
exclude the SCM driver, then I can't really imagine what the use-case
would be for building a kernel which won't work on most Qualcomm
platforms but not simply disabling ARCH_QCOM...
Thanks,
Robin.
