[PATCH 2/4] ata: ahci_brcmstb: disable DIPM support

From: Florian Fainelli <f.fainelli@gmail.com>
Date: 2016-01-08 00:04:34
Also in: linux-arm-kernel, lkml
Subsystem: libata subsystem (serial and parallel ata drivers), the rest · Maintainers: Damien Le Moal, Niklas Cassel, Linus Torvalds

From: Danesh Petigara <redacted>

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.
