Subject: [PATCH net-next 0/5] net: phy: broadcom: IDDQ-SR mode
Date: Mon, 20 Sep 2021 14:54:13 -0700	[thread overview]
Message-ID: <20210920215418.3247054-1-f.fainelli@gmail.com> (raw)

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.
