Subject: [PATCH v3 5/7] ata: ahci: mvebu: request PHY suspend/resume for Armada 3700
Date: Tue,  4 Dec 2018 20:28:29 +0100	[thread overview]
Message-ID: <20181204192831.12440-6-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20181204192831.12440-1-miquel.raynal@bootlin.com>

A feature has been added in the libahci driver: the possibility to set
a new flag in hpriv->flags to let the core handle PHY suspend/resume
automatically. Make use of this feature to make suspend to RAM work
with SATA drives on A3700.
