The patch standardizes the probe() code by replacing the two occurrences of dev_err() with dev_err_probe(). Indeed, dev_err_probe() was used in all other error paths of the probe() function. Note that dev_err_probe() has advantages even if the error code is not EPROBE_DEFER, such as the symbolic output of the error code. Therefore, it should generally be preferred over dev_err().

In the single PM domain case there is no need for platform code to specify the index of the corresponding required OPP in DT, as the index must be zero. This allows us to assign a required dev for the required OPP from genpd, while attaching a device to its PM domain.

In the multiple PM domain case we need platform code to specify the index of the corresponding required OPP in DT for a device, which is what *_opp_attach_genpd() is there to help us with. However, attaching a device to its PM domains is in general better done with dev_pm_domain_attach_list(). To avoid having two different ways to manage this and to prepare for the removal of *_opp_attach_genpd(), let's extend dev_pm_domain_attach|detach_list() to manage the required OPPs too.

At this point there are no consumer drivers that makes use of _set_required_devs(), hence it should be straightforward to rework the code to enable it to better integrate with the PM domain attach procedure. During attach, one device at the time is being hooked up to its corresponding PM domain.

The MediaTek power domain driver contains a hack that assigns the device node of the power domain to the struct device of the power domain controller in order to use the devres regulator API. Now that there is a proper OF-specific regulator API, and even a devres version, replace the hack with proper code. This change is incompatible with incomplete device trees. Instead of assigning the dummy regulator in cases where the power domain requires a supply but the device tree does not provide one, the driver will just error out. This will be seen on the MT8390 EVK, which is missing supplies for the IMG_VCORE and CAM_VCORE domains. And likely all the MediaTek EVBs, which have no power domain supplies specified. This is however the correct behavior. If the power domain's supply is missing, then it should not work. Relying on other parts of the system to keep the unattached regulator enabled is likely to break in ways less easier to understand.

2024-09-30regulator: Add devres version of of_regulator_get_optional()Chen-Yu Tsai4-8/+68
There are existing uses for a devres version of of_regulator_get_optional() in power domain drivers. On MediaTek platforms, power domains may have regulator supplies tied to them. The driver currently tries to use devm_regulator_get() to not have to manage the lifecycle, but ends up doing it in a very hacky way by replacing the device node of the power domain controller device to the device node of the power domain that is currently being registered, getting the supply, and reverting the device node. Provide a better API so that the hack can be replaced.

2024-09-30regulator: Add of_regulator_get_optional() for pure DT regulator lookupChen-Yu Tsai4-8/+69
The to-be-introduced I2C component prober needs to enable regulator supplies (and toggle GPIO pins) for the various components it intends to probe. To support this, a new "pure DT lookup" method for getting regulator supplies is needed, since the device normally requesting the supply won't get created until after the component is probed to be available. Add a new of_regulator_get_optional() function for this. This mirrors the existing regulator_get_optional() function, but is OF-specific. The underlying code that supports the existing regulator_get*() functions has been reworked in previous patches to support this specific case. Also convert an existing usage of "dev && dev->of_node" to "dev_of_node(dev)".

The cpu_emergency_register_virt_callback() function is used unconditionally by the x86 kvm code, but it is declared (and defined) conditionally: #if IS_ENABLED(CONFIG_KVM_INTEL) || IS_ENABLED(CONFIG_KVM_AMD) void cpu_emergency_register_virt_callback(cpu_emergency_virt_cb *callback); ... leading to a build error when neither KVM_INTEL nor KVM_AMD support is enabled: arch/x86/kvm/x86.c: In function ‘kvm_arch_enable_virtualization’: arch/x86/kvm/x86.c:12517:9: error: implicit declaration of function ‘cpu_emergency_register_virt_callback’ [-Wimplicit-function-declaration] 12517 | cpu_emergency_register_virt_callback(kvm_x86_ops.emergency_disable_virtualization_cpu); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ arch/x86/kvm/x86.c: In function ‘kvm_arch_disable_virtualization’: arch/x86/kvm/x86.c:12522:9: error: implicit declaration of function ‘cpu_emergency_unregister_virt_callback’ [-Wimplicit-function-declaration] 12522 | cpu_emergency_unregister_virt_callback(kvm_x86_ops.emergency_disable_virtualization_cpu); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Fix the build by defining empty helper functions the same way the old cpu_emergency_disable_virtualization() function was dealt with for the same situation. Maybe we could instead have made the call sites conditional, since the callers (kvm_arch_{en,dis}able_virtualization()) have an empty weak fallback. I'll leave that to the kvm people to argue about, this at least gets the build going for that particular config.
