Merge tag 'pci-v5.20-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci
Pull pci updates from Bjorn Helgaas: "Enumeration:
- Consolidate duplicated 'next function' scanning and extend to allow 'isolated functions' on s390, similar to existing hypervisors (Niklas Schnelle)
Resource management: - Implement pci_iobar_pfn() for sparc, which allows us to remove the sparc-specific pci_mmap_page_range() and pci_mmap_resource_range().
This removes the ability to map the entire PCI I/O space using /proc/bus/pci, but we believe that's already been broken since v2.6.28 (Arnd Bergmann)
- Move common PCI definitions to asm-generic/pci.h and rework others to be be more specific and more encapsulated in arches that need them (Stafford Horne)
Power management:
- Convert drivers to new *_PM_OPS macros to avoid need for '#ifdef CONFIG_PM_SLEEP' or '__maybe_unused' (Bjorn Helgaas)
Virtualization:
- Add ACS quirk for Broadcom BCM5750x multifunction NICs that isolate the functions but don't advertise an ACS capability (Pavan Chebbi)
Error handling:
- Clear PCI Status register during enumeration in case firmware left errors logged (Kai-Heng Feng)
- When we have native control of AER, enable error reporting for all devices that support AER. Previously only a few drivers enabled this (Stefan Roese)
- Keep AER error reporting enabled for switches. Previously we enabled this during enumeration but immediately disabled it (Stefan Roese)
- Iterate over error counters instead of error strings to avoid printing junk in AER sysfs counters (Mohamed Khalfella)
ASPM:
- Remove pcie_aspm_pm_state_change() so ASPM config changes, e.g., via sysfs, are not lost across power state changes (Kai-Heng Feng)
Endpoint framework:
- Don't stop an EPC when unbinding an EPF from it (Shunsuke Mie)
Endpoint embedded DMA controller driver:
- Simplify and clean up support for the DesignWare embedded DMA (eDMA) controller (Frank Li, Serge Semin)
Broadcom STB PCIe controller driver:
- Avoid config space accesses when link is down because we can't recover from the CPU aborts these cause (Jim Quinlan)
- Look for power regulators described under Root Ports in DT and enable them before scanning the secondary bus (Jim Quinlan)
- Disable/enable regulators in suspend/resume (Jim Quinlan)
Freescale i.MX6 PCIe controller driver:
- Simplify and clean up clock and PHY management (Richard Zhu)
- Disable/enable regulators in suspend/resume (Richard Zhu)
- Set PCIE_DBI_RO_WR_EN before writing DBI registers (Richard Zhu)
- Allow speeds faster than Gen2 (Richard Zhu)
- Make link being down a non-fatal error so controller probe doesn't fail if there are no Endpoints connected (Richard Zhu)
Loongson PCIe controller driver:
- Add ACPI and MCFG support for Loongson LS7A (Huacai Chen)
- Avoid config reads to non-existent LS2K/LS7A devices because a hardware defect causes machine hangs (Huacai Chen)
- Work around LS7A integrated devices that report incorrect Interrupt Pin values (Jianmin Lv)
Marvell Aardvark PCIe controller driver:
- Add support for AER and Slot capability on emulated bridge (Pali Rohár)
MediaTek PCIe controller driver:
- Add Airoha EN7532 to DT binding (John Crispin)
- Allow building of driver for ARCH_AIROHA (Felix Fietkau)
MediaTek PCIe Gen3 controller driver:
- Print decoded LTSSM state when the link doesn't come up (Jianjun Wang)
NVIDIA Tegra194 PCIe controller driver:
- Convert DT binding to json-schema (Vidya Sagar)
- Add DT bindings and driver support for Tegra234 Root Port and Endpoint mode (Vidya Sagar)
- Fix some Root Port interrupt handling issues (Vidya Sagar)
- Set default Max Payload Size to 256 bytes (Vidya Sagar)
- Fix Data Link Feature capability programming (Vidya Sagar)
- Extend Endpoint mode support to devices beyond Controller-5 (Vidya Sagar)
Qualcomm PCIe controller driver:
- Rework clock, reset, PHY power-on ordering to avoid hangs and improve consistency (Robert Marko, Christian Marangi)
- Move pipe_clk handling to PHY drivers (Dmitry Baryshkov)
- Add IPQ60xx support (Selvam Sathappan Periakaruppan)
- Allow ASPM L1 and substates for 2.7.0 (Krishna chaitanya chundru)
- Add support for more than 32 MSI interrupts (Dmitry Baryshkov)
Renesas R-Car PCIe controller driver:
- Convert DT binding to json-schema (Herve Codina)
- Add Renesas RZ/N1D (R9A06G032) to rcar-gen2 DT binding and driver (Herve Codina)
Samsung Exynos PCIe controller driver:
- Fix phy-exynos-pcie driver so it follows the 'phy_init() before phy_power_on()' PHY programming model (Marek Szyprowski)
Synopsys DesignWare PCIe controller driver:
- Simplify and clean up the DWC core extensively (Serge Semin)
- Fix an issue with programming the ATU for regions that cross a 4GB boundary (Serge Semin)
- Enable the CDM check if 'snps,enable-cdm-check' exists; previously we skipped it if 'num-lanes' was absent (Serge Semin)
- Allocate a 32-bit DMA-able page to be MSI target instead of using a driver data structure that may not be addressable with 32-bit address (Will McVicker)
- Add DWC core support for more than 32 MSI interrupts (Dmitry Baryshkov)
Xilinx Versal CPM PCIe controller driver:
- Add DT binding and driver support for Versal CPM5 Gen5 Root Port (Bharat Kumar Gogada)"

PCI: microchip: Fix refcount leak in mc_pcie_init_irq_domains()
of_get_next_child() returns a node pointer with refcount incremented, so we should use of_node_put() on it when we don't need it anymore.
mc_pcie_init_irq_domains() only calls of_node_put() in the normal path, missing it in some error paths. Add missing of_node_put() to avoid refcount leak.

PCI: microchip: Fix potential race in interrupt handling
Clear the MSI bit in ISTATUS_LOCAL register after reading it, but before reading and handling individual MSI bits from the ISTATUS_MSI register. This avoids a potential race where new MSI bits may be set on the ISTATUS_MSI register after it was read and be missed when the MSI bit in the ISTATUS_LOCAL register is cleared.
ISTATUS_LOCAL is a read/write/clear register; the register's bits are set when the corresponding interrupt source is activated. Each source is independent and thus multiple sources may be active simultaneously. The processor can monitor and clear status bits. If one or more ISTATUS_LOCAL interrupt sources are active, the RootPort issues an interrupt towards the processor (on the AXI domain). Bit 28 of this register reports an MSI has been received by the RootPort.
ISTATUS_MSI is a read/write/clear register. Bits 31-0 are asserted when an MSI with message number 31-0 is received by the RootPort. The processor must monitor and clear these bits.
Effectively, Bit 28 of ISTATUS_LOCAL informs the processor that an MSI has arrived at the RootPort and ISTATUS_MSI informs the processor which MSI (in the range 0 - 31) needs handling.
