Daniel Mack c2b32e580c net: ethernet: cpsw: improve interrupt lookup logic in cpsw_probe()
Simplify the interrupt resource lookup code in cpsw_probe() by the
following:

 * Only look at the first member of the resource. As the driver only
   works for DT-enabled platforms anyway, a resource of type
   IORESOURCE_IRQ will only contain one single entry
   (res->start == res->end), so there is no need for the iteration.

 * Add a bounds check to avoid overflows if we are passed more than
   ARRAY_SIZE(priv->irqs_table) resources.

 * Assign 'ret' with the return value of devm_request_irq() so that
   cpsw_probe() returns the appropriate error code.

 * If devm_request_irq() fails, report the error code in the log
   message.

Mugunthan V N e6afea0bbf drivers: net: cpsw: fix dual EMAC stall when connected to same switch
In commit 629c9a8fd0 (drivers: net: cpsw: Add
default vlan for dual emac case also), api cpsw_add_default_vlan() also
changes the port vlan which is required to seperate the ports which results
in the following behavior

In Dual EMAC mode, when both the Etnernet connected is connected to same
switch, it creates a loop in the switch and when a broadcast packet is
received it is forwarded to the other port which stalls the whole switch
and needs a reset/power cycle to the switch to recover. So intead of using
the api, add only the default VLAN entry in dual EMAC case.

Johan Hovold 6954cc1f23 net: cpsw: fix null dereference at probe
Fix null-pointer dereference at probe when the mdio platform device is
missing (e.g. when it has been disabled in DT).

Johan Hovold 59993f48b3 Revert "net: eth: cpsw: Correctly attach to GPIO bitbang MDIO driver"
This reverts commit f8d56d8f89 ("net:
 eth: cpsw: Correctly attach to GPIO bitbang MDIO driver").

Fix potential null-pointer dereference at probe if the mdio-gpio device
has not been successfully probed yet.

The offending commit is plain wrong for a number of reasons. First of
all it accesses internal driver data of an unrelated device. Neither
does it check that the data is non-null (which it is in case the device
has not been probed yet).

Furthermore, the decision on whether to treat any driver data according
to the mdio-gpio driver's internals is made based on the node name. But
the name is not compared against "mdio" which is the normal name for the
node, but rather against "gpio" which the node does not have to be named
(and shouldn't be according to the binding documentation). [ If this
hack is to be kept out-of-tree it should at least be matching against
the compatible property. ]

George Cherian 09c5537246 drivers: net: cpsw: Enable Annexe F Time sync
Enable the Annex F Time Sync explicitly for DRA7x and AM4372.
With this enabled the L2 PTP is working.

while at that rename TS_BIT8 to TS_TTL_NONZERO
