…NUX_QCOM_KERNEL_DEVICETREE Include the qcs6490-rb3gen2-indsutrial-mezzanine-staging.dtbo overlay in the LINUX_QCOM_KERNEL_DEVICETREE list for Rb3Gen2 Industrial Kit. This overlay will be used to define properties required by the out-of-tree QPS615 ethernet driver. Signed-off-by: Mohd Ayaan Anwar <mohd.anwar@oss.qualcomm.com>
…as overlay for QPS615 The Rb3Gen2 Industrial Kit has 3x QPS615 PCIe switches, out of which 2 of them provide dual ethernet ports. The ports are enabled by an out-of-tree driver which needs devicetree support for accessing platform resources. Add a staging dtbo in FIT DTB compatibility so that can overlay can be picked for the Rb3Gen2 Industrial Kit configuration, via an EFI variable.

This series adds Device Tree overlay (DTBO) support for the QPS615 PCIe Ethernet switch on the RB3Gen2 Industrial Mezzanine board. The RB3Gen2 Industrial Kit carries 3x QPS615 PCIe switches, of which 2 have dual ethernet ports. The QPS615's Ethernet functionality is enabled by an out-of-tree kernel driver (qps615-dlkm) that requires platform-specific devicetree properties to access hardware resources.
This is a "staging" DTBO due to its downstream nature; it lives in the LINUX_QCOM_KERNEL_DEVICETREE list and is referenced via a FIT_DTB_COMPATIBLE overlay combination in the FIT image.
This PR depends on kernel changes to add the dtso's to qcom-next and qcom-6.18.y branches. They still need to be merged and consumed by their revision tag in meta-qcom.
Exception details: Until the QPS615 driver is upstreamed to the kernel (third-party ETA: end of 2026), an exception has been approved to include the driver + DT overlay (QLIJIRA-99).
