Subject: [PATCH v1 0/3] Add support for detecting Controller Level PCIe Errors

From: Mrinmay Sarkar <quic_msarkar@...cinc.com>

Synopsys Controllers provide capabilities to detect various controller
level errors. These can range from controller interface error to random
PCIe configuration errors. This patch intends to add support to detect
these errors and report it to userspace entity via sysfs, which can take
appropriate actions to mitigate the errors.

Also adding global irq support for PCIe RC and add corresponding change
in PCIe dt-bindings.

  dt-bindings: PCI: qcom: Add global irq support for SA8775p
  arm64: dts: qcom: sa8775p: Enable global irq support for SA8775p
