Subject: [PATCH v3 04/14] PCI: dwc: Kconfig: Add iMX PCIe EP mode support
Date:   Fri, 23 Sep 2022 14:06:50 +0800
Message-Id: <1663913220-9523-5-git-send-email-hongxing.zhu@nxp.com>
In-Reply-To: <1663913220-9523-1-git-send-email-hongxing.zhu@nxp.com>
References: <1663913220-9523-1-git-send-email-hongxing.zhu@nxp.com>
Precedence: bulk

Since i.MX PCIe is one dual mode PCIe controller.
Add i.MX PCIe EP mode support, and split the PCIe modes to the Root
Complex mode and Endpoint mode.
