Subject: dt: bindings: net: use boolean dt properties for eee broken modes
From: jbrunet <jbrunet@xxxxxxxxxxxx>
[ Upstream commit 308d3165d8b2b98d3dc3d97d6662062735daea67 ]
The patches regarding eee-broken-modes was merged before all people
involved could find an agreement on the best way to move forward.
While we agreed on having a DT property to mark particular modes as broken,
the value used for eee-broken-modes mapped the phy register in very direct
way. Because of this, the concern is that it could be used to implement
configuration policies instead of describing a broken HW.
In the end, having a boolean property for each mode seems to be preferred
over one bit field value mapping the register (too) directly.
