If anyone has any objections, please let me know. ------------------ From: Richard Zhu commit 5214ff221a14cadab1e2ee29499750fd5e884feb upstream. Add IMX6_PCIE_FLAG_HAS_APP_RESET flag to IMX8MM_EP and IMX8MP_EP drvdata. This flag was overlooked during code restructuring. It is crucial to release the app-reset from the System Reset Controller before initiating LTSSM to rectify the issue.
