The CPSW driver remaps two different IO regions, but fails to unmap them
both. This patch fixes the issue by calling iounmap in the appropriate
places.

This patch adds a driver for the CPTS that offers time

frequency adjustment, we have implemented this in software
by changing the multiplication factor of the timecounter.

For RMII/RGMII mode operation in 100Mbps, the CPSW needs to set the
IFCTL_A bits in the MACCONTROL register. For all other PHY modes, this
bit is unused, so setting it unconditionally shouldn't cause any
trouble.

PHY connect attempts fail if no PHY id is specified in the emac platform
data and another mdio bus has been registered before 'davinci_mdio' bus. In
this case when configuring the interface, there will be an attempt to
connect to already attached PHY on the previously registered mdio bus:

net eth1: PHY already attached
net eth1: could not connect to phy smsc911x-0:01
IP-Config: Failed to open eth1
IP-Config: Device `eth1' not found

Fix this by modifying match_first_device() to match first PHY device

Under heavy load (flood ping) it is possible for the MDIO timeout to
expire before the loop checks the GO bit again. This patch adds an
additional check whether the operation was done before actually
returning -ETIMEDOUT.

To reproduce this bug, flood ping the device, e.g., ping -f -l 1000
After some time, a "timed out waiting for user access" warning
may appear. And even worse, link may go down since the PHY reported a
timeout.
