From 99cec8a4dda28972067c274a4215422262dc5522 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Tue, 22 Nov 2016 11:40:56 -0800 Subject: [PATCH] net: phy: broadcom: Allow enabling or disabling of EEE In preparation for adding support for Wirespeed/downshift, we need to change bcm_phy_eee_enable() to allow enabling or disabling EEE, so make the function take an extra enable/disable boolean parameter and rename it to illustrate it sets EEE, not necessarily just enables it.
