But this creates issues with PERST# GPIO provided by one of the child devices like the PCIe switch port. In this case, the RC driver cannot acquire the PERST# GPIO since it will be provided by the child PCIe device which was not yet enumerated during RC driver probe. Fix this by checking if the GPIO provider is a child of the RC's DT node (i.e., sits behind this PCIe controller). If so, skip it, as PERST# should be controlled by the respective PCIe client driver implementation. GPIOs provided by external GPIO controllers (e.g., TLMM in Qcom SoCs) continue to be handled normally.
