Subject: [PATCH asahi-soc/dt 04/10] arm64: dts: apple: t7000: Add PMGR node
Date: Tue, 29 Oct 2024 09:04:02 +0800 [thread overview]
Message-ID: <20241029010526.42052-5-towinchenmi@gmail.com> (raw)
In-Reply-To: <20241029010526.42052-1-towinchenmi@gmail.com>
This adds the PMGR node and all known power state subnodes. Since there
are a large number of them, let's put them in a separate file to include.
