Hi, This series adds the Qualcomm specific 'global' IRQ to the supported SoCs. This IRQ is used to receive the PCIe controller and link specific events such as Link Up/Down, MSI, PTM etc... in the driver. Support for this IRQ was already added to the pcie-qcom driver. So enabling this IRQ would allow the driver to enumerate the endpoint device and also retrain the link when the device is removed [1] without user intervention. This series also adds missing MSI SPI IRQ to some of the SoCs. Testing ======= This series was tested on Qualcomm RB5 board based on SM8250 SoC and Qualcomm Ride MX board based on SA8775p SoC. NOTE ==== I've left a few SoCs in the tree like QCS404, SC8280XP due to lack of documentation. Those will be added later.
