Subject: [PATCH net-next v3 1/2] net: phy: marvell10g: implement suspend/resume callbacks
Date: Tue, 26 Mar 2019 15:53:01 +0100 [thread overview]
Message-ID: <20190326145302.9563-2-antoine.tenart@bootlin.com> (raw)
In-Reply-To: <20190326145302.9563-1-antoine.tenart@bootlin.com>
This patch adds the suspend/resume callbacks for Marvell 10G PHYs. The
three PCS (base-t, base-r and 1000base-x) are set in low power (the PCS
are powered down) when the PHY isn't used.
