Re: [PATCH v25 04/10] firmware: psci: Add support for PSCI auxiliary devices
From: sashiko-bot@kernel.org
Date: 2026-09-14 15:21:59
PSCI has multiple kernel consumers, such as cpuidle-psci-domain. Currently, both the PSCI core driver and cpuidle-psci-domain bind directly to the same PSCI node "arm,psci-1.0". Additional consumers, if introduced, would also need to bind in the same way, leading to multiple drivers attached to a single device node. Introduce a PSCI auxiliary-device provider that binds to "arm,psci-1.0" and registers PSCI child devices on the auxiliary bus. As the first user, register cpuidle-psci-domain as an auxiliary device. Update cpuidle-psci-domain to probe as an auxiliary driver and use the PSCI device node for power-domain traversal.
