Subject: [PATCH 2/4] ata: ahci_brcmstb: disable DIPM support
Date: Thu, 7 Jan 2016 16:03:31 -0800 [thread overview]
Message-ID: <1452211413-1350-3-git-send-email-f.fainelli@gmail.com> (raw)
In-Reply-To: <1452211413-1350-1-git-send-email-f.fainelli@gmail.com>
From: Danesh Petigara <dpetigara@broadcom.com>
The Broadcom STB SATA host controller does not support device
initiated power management. Disable support for this feature
so the driver never sends SETFEATURES commands to the device
to enable/disable DIPM.
