Subject: [PATCH 0/2] regulator: freeze delayed hardware access during suspend
Date: Fri, 16 Oct 2026 18:05:20 +0800	[thread overview]
Message-ID: <20261016100522.2582557-1-yaojiale02@163.com> (raw)

Deferred regulator disable and IRQ recovery callbacks can perform hardware
access after a caller-provided delay. Their current workqueues remain active
while devices are being suspended, allowing the callbacks to reach a
regulator after its backing bus has been suspended.

Move deferred disable to the freezable power-efficient workqueue. Move IRQ
helper callbacks to a freezable workqueue as well, while retaining the
high-priority property for users that request it. Each patch is independent
and can be applied separately.
