Stephan Gerhold c09f1248b1 cpuidle: qcom-spm: Check if any CPU is managed by SPM ... [ Upstream commit 0ee30ace67 ] At the moment, the "qcom-spm-cpuidle" platform device is always created, even if none of the CPUs is actually managed by the SPM. On non-qcom platforms this will result in infinite probe-deferral due to the failing qcom_scm_is_available() call. To avoid this, look through the CPU DT nodes and check if there is actually any CPU managed by a SPM (as indicated by the qcom,saw property). It should also be available because e.g. MSM8916 has qcom,saw defined but it's typically not enabled with ARM64/PSCI firmwares. This is needed in preparation of a follow-up change that calls qcom_scm_set_warm_boot_addr() a single time before registering any cpuidle drivers. Otherwise this call might be made even on devices that have this driver enabled but actually make use of PSCI.
