Subject: [PATCH v4 01/12] PCI: imx6: Fix establish link failure in EP mode for iMX8MM and iMX8MP
Date: Tue, 07 May 2024 14:45:39 -0400 [thread overview]
Message-ID: <20240507-pci2_upstream-v4-1-e8c80d874057@nxp.com> (raw)
In-Reply-To: <20240507-pci2_upstream-v4-0-e8c80d874057@nxp.com>
From: Richard Zhu <hongxing.zhu@nxp.com>
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
Fixes: 0c9651c21f2a ("PCI: imx6: Simplify reset handling by using *_FLAG_HAS_*_RESET")
