[PATCH 4.14 096/146] net: dsa: bcm_sf2: Clear IDDQ_GLOBAL_PWR bit for PHY

[Greg Kroah-Hartman]

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Florian Fainelli <f.faine...@gmail.com>


[ Upstream commit 4b52d010113e11006a389f2a8315167ede9e0b10 ]

The PHY on BCM7278 has an additional bit that needs to be cleared:
IDDQ_GLOBAL_PWR, without doing this, the PHY remains stuck in reset out
of suspend/resume cycles.

switch")
