[PATCH 02/14] pinctrl: pinctrl-single: move suspend/resume to suspend_noirq/resume_noirq

From: Thomas Richard
Date: Mon Jan 15 2024 - 11:17:32 EST


The goal is to extend the active period of pinctrl.
Some devices may need active pinctrl after suspend and/or before resume.
So move suspend/resume to suspend_noirq/resume_noirq to have active
pinctrl until suspend_noirq (included), and from resume_noirq
(included).

The deprecated API has been removed to use the new one (dev_pm_ops struct).
