Subject: [PATCH V7 08/13] arm: dts: imx7d: Add Root Port node and PERST property
Date: Tue, 10 Mar 2026 09:54:21 +0800 [thread overview]
Message-ID: <20260310015426.365675-9-sherry.sun@nxp.com> (raw)
In-Reply-To: <20260310015426.365675-1-sherry.sun@nxp.com>
Since describing the PCIe PERST# property under Host Bridge node is now
deprecated, it is recommended to add it to the Root Port node, so
creating the Root Port node and add the reset-gpios property in Root
Port.
