Merge branch 'phy-broken-modes'
Jerome Brunet says:
====================
phy: Fix integration of eee-broken-modes
The purpose of this series is to fix the integration of the ethernet phy
property "eee-broken-modes" [0]
The v3 of this series has been merged, missing a fix (error reported by
kbuild robot) available in the v4 [1]
More importantly, Florian opposed adding a DT property mapping a device
register this directly [2]. The concern was that the property could be
abused to implement platform configuration policy. After discussing it,
I think we agreed that such information about the HW (defect) should appear
in the platform DT. However, the preferred way is to add a boolean property
for each EEE broken mode.
