From: Miquel Raynal Date: Tue, 4 Dec 2018 19:28:29 +0000 (+0100) Subject: ata: ahci: mvebu: request PHY suspend/resume for Armada 3700 X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=bde0b5c109e8b22b57745e3b9914f9e87ad857ea;p=openwrt%2Fstaging%2Fblogic.git ata: ahci: mvebu: request PHY suspend/resume for Armada 3700 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.
