Merge patch series "Support power resources defined in acpi on ata"
Markus Probst <markus.probst@posteo.de> says:
This series adds support for power resources defined in acpi on ata
ports/devices. A device can define a power resource in an ata port/device,
which then gets powered on right before the port is probed. This can be
useful for devices, which have sata power connectors that are:
a: powered down by default
b: can be individually powered on
like in some synology nas devices. If thats the case it will be assumed,
that the power resource won't survive reboots and therefore the disk will
be stopped.
