AngeloGioacchino Del Regno 60f3692b5f cpuidle: qcom_spm: Detach state machine from main SPM handling ... In commit a871be6b8e ("cpuidle: Convert Qualcomm SPM driver to a generic CPUidle driver") the SPM driver has been converted to a generic CPUidle driver: that was mainly made to simplify the driver and that was a great accomplishment; Though, at that time, this driver was only applicable to ARM 32-bit SoCs, lacking logic about the handling of newer generation SAW. In preparation for the enablement of SPM features on AArch64/ARM64, split the cpuidle-qcom-spm driver in two: the CPUIdle related state machine (currently used only on ARM SoCs) stays there, while the SPM communication handling lands back in soc/qcom/spm.c and also making sure to not discard the simplifications that were introduced in the aforementioned commit. Since now the "two drivers" are split, the SCM dependency in the main SPM handling is gone and for this reason it was also possible to move the SPM initialization early: this will also make sure that whenever the SAW CPUIdle driver is getting initialized, the SPM driver will be ready to do the job. Please note that the anticipation of the SPM initialization was also done to optimize the boot times on platforms that have their CPU/L2 idle states managed by other means (such as PSCI), while needing SAW initialization for other purposes, like AVS control.
