#1211366 — [PATCH] phylib: Make PHYs children of their MDIO bus, not the bus' parent.

FromDavid Daney <ddaney.cavm@gmail.com>
Date2015-08-22 01:20 +0200
Subject[PATCH] phylib: Make PHYs children of their MDIO bus, not the bus' parent.
Message-ID<q03Lk-1jq-11@gated-at.bofh.it>
From: David Daney <david.daney@cavium.com>

commit 18ee49ddb0d2 ("phylib: rename mii_bus::dev to mii_bus::parent")
changed the parent of PHY devices from the bus to the bus parent.

Then, commit 4dea547fef1b ("phylib: rework to prepare for OF
registration of PHYs") moved the code into phy_device.c

At this point, it is somewhat unclear why the change was seen as
necessary.  But, when we look at the device model tree in
/sys/devices, it is clearly incorrect.  The PHYs should be children of
their MDIO bus.

Change the PHY's parent device to be the MDIO bus device.
