Subject: [PATCH net-next v2] net: phy: lxt: Add suspend/resume support to LXT971 and LXT973.
Date: Thu, 23 May 2019 08:55:32 +0000 (UTC) [thread overview]
Message-ID: <eb206b659fcae041be38d583ff139ca73e9e03c3.1558601485.git.christophe.leroy@c-s.fr> (raw)
All LXT PHYs implement the standard "power down" bit 11 of
BMCR, so this patch adds support using the generic
genphy_{suspend,resume} functions added by
commit 0f0ca340e57b ("phy: power management support").
LXT970 is left aside because all registers get cleared upon
"power down" exit.

I'd be happy if you could also merge that into 4.19
v2: revised commit log without the Fixes: tag.
