2021-08-23regulator: Documentation fix for regulator error notification helperMatti Vaittinen
The helper to send IRQ notification for regulator errors had still old description mentioning calling BUG() as a last resort when error status reading has kept failing for more times than a given threshold. The impementation calling BUG() did never end-up in-tree but was replaced by hopefully more sophisticated handler trying to power-off the system. Fix the documentation to reflect actual behaviour.

2021-08-23PCI: hv: Set up MSI domain at bridge probing timeBoqun Feng
Since PCI_HYPERV depends on PCI_MSI_IRQ_DOMAIN which selects GENERIC_MSI_IRQ_DOMAIN, we can use dev_set_msi_domain() to set up the MSI domain at probing time, and this works for both x86 and ARM64. Therefore use it as the preparation for ARM64 Hyper-V PCI support. As a result, no longer need to maintain ->fwnode in x86 specific pci_sysdata, and make hv_pcibus_device own it instead.

No functional change, just store and maintain the PCI domain number in the ->domain_nr of pci_host_bridge. Note that we still need to keep the copy of domain number in x86-specific pci_sysdata, because x86 is not a PCI_DOMAINS_GENERIC=y architecture, so the ->domain_nr of pci_host_bridge doesn't work for it yet.

2021-08-23PCI: hv: Generify PCI probingArnd Bergmann
In order to support ARM64 Hyper-V PCI, we need to set up the bridge at probing time because ARM64 is a PCI_DOMAIN_GENERIC=y arch and we don't have pci_config_window (ARM64 sysdata) for a PCI root bus on Hyper-V, so it's impossible to retrieve the information (e.g. PCI domains, MSI domains) from bus sysdata on ARM64 after creation. Originally in create_root_hv_pci_bus(), pci_create_root_bus() is used to create the root bus and the corresponding bridge based on x86 sysdata. Now we create a bridge first and then call pci_scan_root_bus_bridge(), which allows us to do the necessary set-ups for the bridge.

2021-08-23PCI: Support populating MSI domains of root buses via bridgesBoqun Feng
Currently, at probing time, the MSI domains of root buses are populated if either the information of MSI domain is available from firmware (DT or ACPI), or arch-specific sysdata is used to pass the fwnode of the MSI domain. These two conditions don't cover all, e.g. Hyper-V virtual PCI on ARM64, which doesn't have the MSI information in the firmware and couldn't use arch-specific sysdata because running on an architecture with PCI_DOMAINS_GENERIC=y. To support populating MSI domains of the root buses at the probing when neither of the above condition is true, the ->msi_domain of the corresponding bridge device is used: in pci_host_bridge_msi_domain(), which should return the MSI domain of the root bus, the ->msi_domain of the corresponding bridge is fetched first as a potential value of the MSI domain of the root bus. In order to use the approach to populate MSI domains, the driver needs to dev_set_msi_domain() on the bridge before calling pci_register_host_bridge(), and makes sure GENERIC_MSI_IRQ_DOMAIN=y. Another advantage of this new approach is providing an arch-independent way to populate MSI domains, which allows sharing the driver code as much as possible between architectures.

2021-08-23PCI: Introduce domain_nr in pci_host_bridgeBoqun Feng
Currently we retrieve the PCI domain number of the host bridge from the bus sysdata (or pci_config_window if PCI_DOMAINS_GENERIC=y). Actually we have the information at PCI host bridge probing time, and it makes sense that we store it into pci_host_bridge. One benefit of doing so is the requirement for supporting PCI on Hyper-V for ARM64, because the host bridge of Hyper-V doesn't have pci_config_window, whereas ARM64 is a PCI_DOMAINS_GENERIC=y arch, so we cannot retrieve the PCI domain number from pci_config_window on ARM64 Hyper-V guest. As the preparation for ARM64 Hyper-V PCI support, we introduce the domain_nr in pci_host_bridge and a sentinel value to allow drivers to set domain numbers properly at probing time. Currently CONFIG_PCI_DOMAINS_GENERIC=y archs are only users of this newly-introduced field.

2021-08-23irqchip/qcom-pdc: Trim unused levels of the interrupt hierarchyMarc Zyngier
The QCOM PDC driver creates a bunch of unnecessary levels in the interrupt hierarchy when dealing with non-wakeup-capable interrupts. By definition, these lines are terminated at the PDC level, and everything below this is completely fake. This also results in additional complexity as most of the callbacks have to check for the validity of the parent level. Needless to say, this doesn't look very good. Solve this by disconnecting the interrupt hierarchy below the last valid level, and considerably simplify the handling of all the other interrupts by avoiding now unnecessary cheks. In most cases, the standard irq_*_parent() handlers are directly used. This also cures an issue reporting by Maulik where gpio_to_irq() returns an error after having observed a set of invalid levels.

Commit 4fa82a87ba55 ("opp: Allow required-opps to be used for non genpd use cases") dereferences the pointers in required_opp_tables but these might be set to an ERR_PTR if the list still has lazy links pending, resulting in segfaults. Prior to this patch IS_ERR was also checked on required_opp_tables[i] before reading ->is_genpd inside _opp_table_alloc_required_tables, which is at the same time the predicate to add this table to the lazy list. This segfault is solved by reordering the checks to bail on lazy pending tables before reading ->is_genpd.
