Subject: [PATCH v2 5/5] cpuidle: psci: Move initialization a bit earlier in the boot sequence
Date: Tue, 1 Sep 2026 13:14:08 +0200 [thread overview]
Message-ID: <20260901111441.122436-6-ulf.hansson@oss.qualcomm.com> (raw)
In-Reply-To: <20260901111441.122436-1-ulf.hansson@oss.qualcomm.com>
When using PSCI OS-initiated mode along with the cpuidle-psci-domain driver
it's of great benefit to attach the CPU devices to their CPU PM domains as
soon as possible, as other non-CPU devices sharing the same PM domains
depends on it to allow their devices to be probed.
Let's therefore move to a subsys_initcall, which should be soon enough
after the cpuidle-psci-domain have initialized the PM domain topology.
