[PATCH v2] arm64: defconfig: Enable PCIe hotplug support

From: Krishna Chaitanya Chundru

Date: Sun Sep 06 2026 - 21:37:57 EST


Several Qualcomm SoCs, implement PCIe root ports/root complexes
with native hotplug capability, including root ports used for USB4
PCIe tunneling. Without CONFIG_HOTPLUG_PCI_PCIE, hotplug does not
work on these controllers.

Enable CONFIG_HOTPLUG_PCI_PCIE in the arm64 defconfig so that hotplug
works out of the box on such platforms during bring-up and testing,
without requiring every developer to enable it manually.
