Subject: [PATCH] pinctrl: mediatek: fix suspend/resume timing issue
Date: Fri, 3 Jun 2016 11:28:14 +0800	[thread overview]
Message-ID: <1464924495-20375-1-git-send-email-hongkun.cao@mediatek.com> (raw)

From: "hongkun.cao" <hongkun.cao-NuS5LvNUpcJWk0Htik3J/w@public.gmane.org>

An irq which is a wake up source maybe masked unexpectedly if the wake
up source irq was triggered after pinctrl irqchip suspend and before
suspend_device_irqs finished.
Use *_noirq callbacks to guarantee pinctrl irqchip suspend would be
called after suspend_devices_irqs.
