Subject: [PATCH net-next v2 3/6] mlxsw: reg: Add Management Cable IO and Notifications register
From: Ido Schimmel <idosch@...dia.com>
Add the Management Cable IO and Notifications register. It will be used
to retrieve the power mode status of a module in subsequent patches and
whether a module is present in a cage or not.
