Subject: [PATCH v4 1/2] dt-bindings: PCI: cix,sky1-pcie-host: Add power-domains
Date: Fri, 13 Mar 2026 19:49:13 +0800 [thread overview]
Message-ID: <20260313114914.1564115-2-gary.yang@cixtech.com> (raw)
In-Reply-To: <20260313114914.1564115-1-gary.yang@cixtech.com>
The Sky1 PCIe controller resides in a dedicated power domain managed
via SCMI. Add the power-domains property to the binding to allow
describing this dependency.
