+Subject: [PATCH 8/9] ARM: dts: qcom: add pcie nodes to ipq806x platforms
+
+qcom-pcie driver now supports version 0 of the controller. This change
+adds the corresponding entries to the IPQ806x dtsi file and
+corresponding platform (AP148).

+Subject: [PATCH 9/9] ARM: qcom: automatically select PCI_DOMAINS if PCI is
+ enabled
+
+If multiple PCIe devices are present in the system, the kernel will
+panic at boot time when trying to scan the PCI buses. This happens on
+IPQ806x based platforms, which has 3 PCIe ports.
+
+Enabling this option allows the kernel to assign the pci-domains
+according to the device-tree content. This allows multiple PCIe
+controllers to coexist in the system.

+Subject: [PATCH 9/9] ARM: qcom: automatically select PCI_DOMAINS if PCI is
+ enabled
+
+If multiple PCIe devices are present in the system, the kernel will
+panic at boot time when trying to scan the PCI buses. This happens on
+IPQ806x based platforms, which has 3 PCIe ports.
+
+Enabling this option allows the kernel to assign the pci-domains
+according to the device-tree content. This allows multiple PCIe
+controllers to coexist in the system.
