Subject: [PATCH net-next 0/5] 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.

Florian Fainelli (5):
  net: phy: broadcom: Add IDDQ-SR mode
  net: phy: broadcom: Wire suspend/resume for BCM50610 and BCM50610M
  net: phy: broadcom: Utilize appropriate suspend for BCM54810/11
  net: bcmgenet: Request APD, DLL disable and IDDQ-SR
