The 88m1101 has an errata when configuring autoneg. However, it was
being applied to many other Marvell PHYs as well. Limit its scope to
just the 88m1101.

Device node iterators put the previous value of the index variable, so an
explicit put causes a double put.

In particular, of_mdiobus_register can fail before doing anything
interesting, so one could view it as a no-op from the reference count
point of view.

The API convention makes it that a given MDIO bus reset should be able
to access PHY devices in its reset() callback and perform additional
MDIO accesses in order to bring the bus and PHYs in a working state.

Commit 69226896ad63 ("mdio_bus: Issue GPIO RESET to PHYs.") broke that
contract by first calling bus->reset() and then release all PHYs from
reset using their shared GPIO line, so restore the expected
functionality here.

There is a potential unnecessary refcount decrement on error path of
put_device(&pb->mii_bus->dev), as it is possible to avoid the
of_mdio_find_bus() call if mux_bus is specified by the calling function.

The same put_device() is not called in the error path if the
devm_kzalloc of pb fails.  This caused the variable used in the
put_device() to be changed, as the pb pointer was obviously not set up.

There is an unnecessary of_node_get() on child_bus_node if the
of_mdiobus_register() is successful, as the
for_each_available_child_of_node() automatically increments this.
Thus the refcount on this node will always be +1 more than it should be.

There is no of_node_put() on child_bus_node if the of_mdiobus_register()
call fails.

Finally, it is lacking devm_kfree() of pb in the error path.  While this
might not be technically necessary, it was present in other parts of the
function.  So, I am adding it where necessary to make it uniform.

If an error is encountered in mdio_mux_init(), the error path will call
mdiobus_free().  Since mdiobus_register() has been called prior to
mdio_mux_init(), the bus->state will not be MDIOBUS_UNREGISTERED.  This
causes a BUG_ON() in mdiobus_free().  To correct this issue, add an
error path for mdio_mux_init() which calls mdiobus_unregister() prior to
mdiobus_free().

This patch allows users to enable/disable internal TX and/or RX
clock delay for BCM5481x series PHYs so as to satisfy RGMII timing
specifications.

On a particular platform, whether TX and/or RX clock delay is required
depends on how PHY connected to the MAC IP. This requirement can be
specified through "phy-mode" property in the platform device tree.
