Message-Id: <cf280b7ab1f513f03d3908ac9ad194e819f170f5.1558519026.git.christophe.leroy@c-s.fr> Date: Wed, 22 May 2019 10:01:07 +0000 (UTC) From: Christophe Leroy <christophe.leroy@....fr> To: Andrew Lunn <andrew@...n.ch>, Florian Fainelli <f.fainelli@...il.com>, Heiner Kallweit <hkallweit1@...il.com>, "David S. Miller" <davem@...emloft.net> Cc: linux-kernel@...r.kernel.org, netdev@...r.kernel.org Subject: [PATCH] net: phy: lxt: Add suspend/resume support to LXT971 and LXT973. All LXT PHYs implement the standard "power down" bit 11 of BMCR, so this patch adds support using the generic genphy_{suspend,resume} functions. LXT970 is left aside because all registers get cleared upon "power down" exit.
