[PATCH 0/5] imx ahci DT updates + cubox-i eSATA support

The following series adds several DT properties to the iMX ahci driver,
which are necessary to configure the electrical characteristics of the
SATA interface.

The required electrical characteristics are board dependent, so the
existing solution where the parameters are hard-coded for the first
board(s) which came along is completely rediculous, and cause their
own set of problems: we have to default to these parameters when no
properties are given, and it means we have to use negative properties
to turn stuff off rather than positive properties to enable features.

Yes, I know that the required Documentation/devicetree file is missing,
I couldn't find the existing file to update for this driver with the
new properties. :)

FTTC broadband for 0.8mile line: now at 9.7Mbps down 460kbps up... slowly
improving, and getting towards what was expected from it.
