strcpy() performs no bounds checking on the destination buffer. This could result in linear overflows beyond the end of the buffer, leading to all kinds of misbehaviors. The safe replacement is strscpy(). This is a previous step in the path to remove the strcpy() function entirely from the kernel. Signed-off-by:

AngeloGioacchino Del Regno authored
Implement the support for SAW v4.1, used in at least MSM8998, SDM630, SDM660 and APQ variants and, while at it, also add the configuration for the SDM630/660 Silver and Gold cluster L2 Adaptive Voltage Scaler: this is also one of the prerequisites to allow the OSM controller to perform DCVS. Please note that despite there are various "versions" of these values downstream, these are the only ones that are perfectly stable on the entire set of tested devices. Signed-off-by:

Add devicetree binding for Qualcomm Subsystem Power Manager (SPM). Signed-off-by:

AngeloGioacchino Del Regno authored
In commit a871be6b ("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.
