This patch series adds support for the IDDQ with soft recovery mode which allows power savings of roughly 150mW compared to a simple BMCR.PDOWN power off (called standby power down in Broadcom datasheets).
In order to leverage these modes we add a new PHY driver flags for drivers to opt-in for that behavior, the PHY driver is modified to do the appropriate programming and the PHYs on which this was tested get updated to have an appropriate suspend/resume set of functions.
