From 96be41d74f2ee94203f2a61e55927b028a10fea6 Mon Sep 17 00:00:00 2001 From: Samuel Holland Date: Tue, 16 Feb 2021 22:20:06 -0600 Subject: [PATCH] net: stmmac: dwmac-sun8i: Add a shutdown callback The Ethernet MAC and PHY are usually major consumers of power on boards which may not be able to fully power off (those with no PMIC). Powering down the MAC and internal PHY saves power while these boards are "off". Reviewed-by: Chen-Yu Tsai Signed-off-by: Samuel Holland Signed-off-by: David S.
