From 0e8158b4a82eb5bfb69df17510d210b073896f00 Mon Sep 17 00:00:00 2001 From: Ulf Hansson Date: Wed, 2 Oct 2024 14:22:24 +0200 Subject: OPP: Rework _set_required_devs() to manage a single device per call At this point there are no consumer drivers that makes use of _set_required_devs(), hence it should be straightforward to rework the code to enable it to better integrate with the PM domain attach procedure. During attach, one device at the time is being hooked up to its corresponding PM domain. Therefore, let's update the _set_required_devs() to align to this behaviour, allowing callers to fill out one required_dev per call. Subsequent changes starts making use of this.
