QCOM_SCM and QCOM_SPM are user-selectable drivers, thus ARM_QCOM_SPM_CPUIDLE should rather avoid selecting them but instead depend to avoid any possible unmet dependencies. ARM_QCOM_SPM_CPUIDLE does use symbols from SCM and SPM, and since it cannot be built-in, the dependency must be as built-in. Signed-off-by: Krzysztof Kozlowski <redacted> --- Changes in v2: 1.
