Subject: [PATCH v3 5/6] dt-bindings: PCI: spacemit: Introduce Spacemit K3 PCIe host controller
Date: Fri, 3 Jul 2026 10:00:01 +0800 [thread overview]
Message-ID: <20260703020003.485436-6-inochiama@gmail.com> (raw)
In-Reply-To: <20260703020003.485436-1-inochiama@gmail.com>
Add binding support for the PCIe controller on the SpacemiT K3 SoC.
This controller is almost a standard Synopsys DesignWare PCIe IP,
with some extra link and reset state control.
