2023-04-12PCI: qcom: Enable async probe by defaultManivannan Sadhasivam
Qcom PCIe RC driver waits for the PHY link to be up during the probe; this consumes several milliseconds during boot. Enable async probe by default so that other drivers can load in parallel while this driver waits for the link to be up.

2023-04-12PCI: qcom: Add support for system suspend and resumeManivannan Sadhasivam
During the system suspend, vote for minimal interconnect bandwidth (1KiB) to keep the interconnect path active for config access and also turn OFF the resources like clock and PHY if there are no active devices connected to the controller. For the controllers with active devices, the resources are kept ON as removing the resources will trigger access violation during the late end of suspend cycle as kernel tries to access the config space of PCIe devices to mask the MSIs. Also, it is not desirable to put the link into L2/L3 state as that implies VDD supply will be removed and the devices may go into powerdown state. This will affect the lifetime of storage devices like NVMe. And finally, during resume, turn ON the resources if the controller was truly suspended (resources OFF) and update the interconnect bandwidth based on PCIe Gen speed.

2023-04-11PCI: qcom: Expose link transition counts via debugfsManivannan Sadhasivam
Qualcomm PCIe controllers have debug registers in the MHI region that count PCIe link transitions. Expose them over debugfs to userspace to help debug the low power issues. Note that even though the registers are prefixed as PARF_, they don't live under the "parf" register region. The register naming is following the Qualcomm's internal documentation as like other registers. While at it, let's arrange the local variables in probe function to follow reverse XMAS tree order.

2023-04-11PCI: qcom: Use bulk reset APIs for handling resets for IP rev 2.4.0Manivannan Sadhasivam
All the resets are asserted and deasserted at the same time. So the bulk reset APIs can be used to handle them together. This simplifies the code a lot. It should be noted that there were delays in-between the reset asserts and deasserts. But going by the config used by other revisions, those delays are not really necessary. So a single delay after all asserts and one after deasserts is used. The total number of resets supported is 12 but only ipq4019 is using all of them.

The PCIE part is redundant and 20 doesn't represent anything across the SoCs supported now. So let's get rid of the prefix. This involves adding the IP version suffix to one definition of PARF_SLV_ADDR_SPACE_SIZE that defines offset specific to that version. The other definition is generic for the rest of the versions. Also, the register PCIE20_LNK_CONTROL2_LINK_STATUS2 is not used anywhere, hence removed.

So fix the incorrect register usage which is modifying a different register. Also in this IP version, this register change doesn't depend on MSI being enabled. So remove that check also.

git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull more s390 updates from Heiko Carstens: - Add empty command line parameter handling stubs to kernel for all command line parameters which are handled in the decompressor. This avoids invalid "Unknown kernel command line parameters" messages from the kernel, and also avoids that these will be incorrectly passed to user space. This caused already confusion, therefore add the empty stubs - Add missing phys_to_virt() handling to machine check handler - Introduce and use a union to be used for zcrypt inline assemblies. This makes sure that only a register wide member of the union is passed as input and output parameter to inline assemblies, while usual C code uses other members of the union to access bit fields of it - Add and use a READ_ONCE_ALIGNED_128() macro, which can be used to atomically read a 128-bit value from memory. This replaces the (mis-)use of the 128-bit cmpxchg operation to do the same in cpum_sf code. Currently gcc does not generate the used lpq instruction if __READ_ONCE() is used for aligned 128-bit accesses, therefore use this s390 specific helper - Simplify machine check handler code if a task needs to be killed because of e.g. register corruption due to a machine malfunction - Perform CPU reset to clear pending interrupts and TLB entries on an already stopped target CPU before delegating work to it - Generate arch/s390/boot/vmlinux.map link map for the decompressor, when CONFIG_VMLINUX_MAP is enabled for debugging purposes - Fix segment type handling for dcssblk devices.

2023-03-02genirq/msi, platform-msi: Ensure that MSI descriptors are unreferencedThomas Gleixner
Miquel reported a warning in the MSI core which is triggered when interrupts are freed via platform_msi_device_domain_free(). This code got reworked to use core functions for freeing the MSI descriptors, but nothing took care to clear the msi_desc->irq entry, which then triggers the warning in msi_free_msi_desc() which uses desc->irq to validate that the descriptor has been torn down. The same issue exists in msi_domain_populate_irqs(). Up to the point that msi_free_msi_descs() grew a warning for this case, this went un-noticed. Provide the counterpart of msi_domain_populate_irqs() and invoke it in platform_msi_device_domain_free() before freeing the interrupts and MSI descriptors and also in the error path of msi_domain_populate_irqs().

2023-03-02watchdog: at91rm9200: Only warn once about problems in .remove()Uwe Kleine-König
The single difference between returning 0 and returning an error code in a platform remove callback is that in the latter case the platform core emits a warning about the error being ignored. at91wdt_remove() already emits a warning in the error case, so suppress the more generic (and less helpful) one by returning 0.
