* firmware: qcom: scm: Add support for MC boot address APIStephan Gerhold2021-10-232-17/+71
| | | | | | | | | | | | | | | | | | | | It looks like the old QCOM_SCM_BOOT_SET_ADDR API is broken on some MSM8916 firmware versions that implement the newer SMC32 calling convention. It just returns -EINVAL no matter which arguments are being passed. This does not cause any problems downstream because it first tries to use the new multi-cluster API replacement which is working fine. Implement support for the multi-cluster variant of the SCM call by attempting it first but still fallback to the old call in case of an error. Also, to be absolutely sure only use the multi-cluster variant with the SMC calling convention since older platforms should not need this.

* soc: qcom: rpmhpd: Make power_on actually enable the domainBjorn Andersson2021-10-151-4/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The general expectation is that powering on a power-domain should make the power domain deliver some power, and if a specific performance state is needed further requests has to be made. But in contrast with other power-domain implementations (e.g. rpmpd) the RPMh does not have an interface to enable the power, so the driver has to vote for a particular corner (performance level) in rpmh_power_on(). But the corner is never initialized, so a typical request to simply enable the power domain would not actually turn on the hardware. Further more, when no more clients vote for a performance state (i.e. the aggregated vote is 0) the power domain would be turned off. Fix both of these issues by always voting for a corner with non-zero value, when the power domain is enabled. The tracking of the lowest non-zero corner is performed to handle the corner case if there's ever a domain with a non-zero lowest corner, in which case both rpmh_power_on() and rpmh_rpmhpd_set_performance_state() would be allowed to use this lowest corner.

* soc: qcom: smem: Support reserved-memory descriptionBjorn Andersson2021-10-142-18/+40
| | | | | | | | | | | | | | | | | | | | | | Practically all modern Qualcomm platforms has a single reserved-memory region for SMEM. So rather than having to describe SMEM in the form of a node with a reference to a reserved-memory node, allow the SMEM device to be instantiated directly from the reserved-memory node. The current means of falling back to dereferencing the "memory-region" is kept as a fallback, if it's determined that the SMEM node is a reserved-memory node. The "qcom,smem" compatible is added to the reserved_mem_matches list, to allow the reserved-memory device to be probed. In order to retain the readability of the code, the resolution of resources is split from the actual ioremapping.

| | | | | | | | | | | | | | | | | | In the olden days the Qualcomm shared memory (SMEM) region consisted of multiple chunks of memory, so SMEM was described as a standalone node with references to its various memory regions. But practically all modern Qualcomm platforms has a single reserved memory region used for SMEM. So rather than having to use two nodes to describe the one SMEM region, update the binding to allow the reserved-memory region alone to describe SMEM. The olden format is preserved as valid, as this is widely used already.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | APR and other packet routers like GPR are pretty much same and interact with other drivers in similar way.

Apart from this the rest of the functionality is pretty much identical across APR and GPR. Make the apr code more reusable by abstracting it service level, rather than device level so that we do not need to write new drivers for other new packet routers like GPR.

| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | cpuidle: qcom_spm: Detach state machine from main SPM handlingAngeloGioacchino Del Regno2021-09-216-250/+336

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.
