Merge branch 'iddq-sr-mode'
Florian Fainelli says:
====================
net: phy: broadcom: IDDQ-SR mode
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.
