Subject: [PATCH v2 0/3] soc: apple: Add "PMGR misc" power controls driver
Date: Fri, 03 Jul 2026 14:44:10 +0200 [thread overview]
Message-ID: <20260703-pmgr-misc-v2-0-4b26ba10c5a4@chaosmail.tech> (raw)
Certain Apple SoCs have additional power state controls that are using
a separate "misc" mmio interface. Currently this includes the fabric
and memory controllers on pro/max/ultra SoCs.
This series adds a driver to put those in a low power state when the
machine enters sleep. The power savings are SoC-dependent and are
around 1W.
