ARM: OMAP3+: hwmod: Add AM33XX HWMOD data for davinci_mdio module

This patch adds hwmod entry for davinci MDIO module,
creating parent<->child relationship between CPSW and MDIO module.

This Parent-child relation is required in order to use common resources
like, clock, but still maintaining the logical separation between them.

CPGMAC SubSystem consist of various sub-modules, like, mdio, cpdma,
cpsw, etc... These sub-modules are also used in some of Davinci
family of devices, so separate and independent platform devices &
drivers for CPSW and MDIO is implemented.
In case of AM33XX, the resources are shared and common register
bit-field is provided to control module/clock enable/disable,
makes it difficult to handle common resources from both drivers.

So the solution is, create parent<->child relationship between
CPGMAC & MDIO modules.

6 years agonet: cpsw: Add parent<->child relation support between cpsw and mdio
Vaibhav Hiremath [Wed, 14 Nov 2012 09:07:55 +0000]
net: cpsw: Add parent<->child relation support between cpsw and mdio

CPGMAC SubSystem consist of various sub-modules, like, mdio, cpdma,
cpsw, etc... These sub-modules are also used in some of Davinci family
of devices. Now based on requirement, use-case and available technology
nodes the integration of these sub-modules varies across devices.

So coming back to Linux net driver, currently separate and independent
platform devices & drivers for CPSW and MDIO is implemented. In case of
Davinci they both has separate control, from resources perspective,
like clock.

In case of AM33XX, the resources are shared and only one register
bit-field is provided to control module/clock enable/disable, makes it
difficult to handle common resource.

So the solution here implemented in this patch is,

Create parent<->child relationship between both the drivers, making
CPSW as a parent and MDIO as its child and enumerate all the child nodes
under CPSW module.
Both the drivers will function exactly the way it was operating before,
including runtime-pm functionality. No change is required in MDIO driver
(for that matter to any child driver).

As this is only supported during DT boot, the parent<->child relationship
is created and populated in DT execution flow. The only required change
is inside DTS file, making MDIO as a child to CPSW node.

net: davinci_mdio: Fix typo mistake in calling runtime-pm api

By mistake (most likely a copy-paste), instead of pm_runtime_get_sync()
api, driver is calling pm_runtime_put_sync() api in resume callback
function. The bug was introduced by commit id (ae2c07aaf74:
davinci_mdio: runtime PM support).

Now, the reason why it didn't impact functionality is, the patch has
been tested on AM335x-EVM and BeagleBone platform while submitting;
and in case of AM335x the MDIO driver doesn't control the module
enable/disable part, which is handled by CPSW driver.

John W. Linville says:

====================
Included is a Bluetooth pull -- Gustavo says:

"These are the Bluetooth bits for inclusion in 3.8, there is basically one big
thing here which is the High Speed patches from Andrei, he did a lot of work on
A2MP and management of AMP devices. The rest are mostly clean up and bug
fixes."

Also included is an NFC pull -- Samuel says:

"With this one we have:

- pn544 p2p support.
- pn544 physical and HCI layers separation. We are getting the pn544 driver
  ready to support non i2c physical layers.
- LLCP SNL (Service Name Lookup). This is the NFC p2p service discovery
  protocol.
- LLCP datagram sockets (connection less) support.
- IDR library usage for NFC devices indexes assignement.
- NFC netlink extension for setting and getting LLCP link characteristics.
- Various code style fixes and cleanups spread over the pn533, LLCP, HCI and
  pn544 code."

There are a couple of mac80211 pulls as well -- Johannes says:

"Please pull my mac80211-next tree to get the first round of new features
for 3.8. We have:
 * finally, the mac80211 multi-channel work
 * scan improvements:
   - bg scan
   - scan flush
   - forced AP scan
 * cfg80211 tracing
 * a bit of new code to allow implementing SAE (secure authentication of
   equals) in managed mode

Along with a few random improvements, features and fixes."

and...

"Please pull from mac80211-next (per below pull request) to get a few
updates. Most important is probably the fix for the WDS regression that
my previous pull request introduced. Other than that, I have some
tracing code, two mesh updates and a change to allow drivers to
calculate the AES CMAC subkeys without having to implement the GF_mulx
operation themselves."

On top of that are the usual updates to iwlwifi, ath9k, rt2x00,
brcmfmac, mwifiex, and a few others here and there.  Of note is the
addition of the ar5523 driver, ported from an original FreeBSD driver.

This is Linux bridge implementation of root port guard.
If BPDU is received from a leaf (edge) port, it should not
be elected as root port.

Why would you want to do this?
If using STP on a bridge and the downstream bridges are not fully
trusted; this prevents a hostile guest for rerouting traffic.

Why not just use netfilter?
Netfilter does not track of follow spanning tree decisions.
It would be difficult and error prone to try and mirror STP
resolution in netfilter module.

bridge: implement BPDU blocking

This is Linux bridge implementation of STP protection
(Cisco BPDU guard/Juniper BPDU block). BPDU block disables

Why would you want to do this?
If running Spanning Tree on bridge, hostile devices on the network
may send BPDU and cause network failure. Enabling bpdu block
will detect and stop this.

How to recover the port?
The port will be restarted if link is brought down, or
removed and reattached.  For example:
 # ip li set dev eth0 down; ip li set dev eth0 up

bridge: bridge port parameters over netlink

Expose bridge port parameter over netlink. By switching to a nested

This changes IFLA_PROTINFO attribute from one byte to a full nested

batman-adv: roaming handling mechanism redesign

This patch allows clients to roam multiple times within the same
originator-interval.

To enable this new feature two key aspects that have been introduced:
1) packets are always directed to the node that was originally
serving the roamed client which will then re-route the data
to the correct destination at any point in time;
2) the client flags handling mechanism has been properly modified
in order to allow multiple roamings withinin the same orig-int.
Therefore flags are now set properly even in this scenario.

Antonio Quartulli [Sun, 23 Sep 2012 20:38:34 +0000]
batman-adv: substitute tt_poss_change with a per-tt_entry flag

tt_poss_change is a node-wide flag which tells whether the node is in a roaming
state (a client recently moved to/away from it) in order to let it apply special
re-routing rules. However this flag does not give a clear idea of the current
state because it is not possible to understand *which client* is actually
involved in the roaming. For this reason a better approach has been chosen:
instead of using a node-wide variable, the roaming state is now given by a
per-tt_entry ROAM flag which, in case of packet coming through the node, tells
the node whether the real destination is in roaming state or not.

With this flag change, batadv_check_unicast_ttvn() has also been rearranged in
order to better fit the new re-routing logic and to be much more readable.

7 years agogianfar: ethernet vanishes after restoring from hibernation
Wang Dongsheng [Fri, 9 Nov 2012 04:43:51 +0000]
gianfar: ethernet vanishes after restoring from hibernation

If a gianfar ethernet device is down prior to hibernating a
system, it will no longer be present upon system restore.

For example:

~# ifconfig eth0 down
~# echo disk > /sys/power/state

  <trigger a restore from hibernation>

~# ifconfig eth0 up
SIOCSIFFLAGS: No such device

This happens because the restore function bails out early upon
finding devices that were not up at hibernation.  In doing so,
it never gets to the netif_device_attach call at the end of
the restore function.  Adding the netif_device_attach as done
here also makes the gfar_restore code consistent with what is
done in the gfar_resume code.

when something goes wrong, a flood of these messages can be
generated by usbnet (thousands per second).  This doesn't
generally *help* the condition so this patch ratelimits the

There's an underlying problem in usbnet's kevent deferral
mechanism which needs fixing, specifically that events *can*
get dropped and not handled.  This patch doesn't address this,
