9120bd6e9f net: davinci_emac: Get device dm816x MAC address using the cpsw code
At least on dm81xx, we can get the davinci_emac MAC address the same
way as on am33xx cpsw.

Let's also use ether_addr_copy() for davinci_emac while at it.

e5a49c1e3b net: cpsw: Add a minimal cpsw-common module for shared code
Looks like davinci_emac and cpsw can share some code although the
device registers have a different layout.

At least the code for getting the MAC address using syscon can
be shared by passing the register offset. Let's start with that
and set up a minimal shared cpsw-shared.c.

fad7097228 Bluetooth: btusb: Use wait_on_bit_timeout() for BTUSB_BOOTING
The wait_on_bit_timeout() is a simpler and race-free way of waiting for
a bit to be cleared than the current code in btusb.c. This patch updates
the code to use the helper function (its btusb copy - to be later
updated to use a global one).

a087a98e07 Bluetooth: btusb: Fix race when waiting for BTUSB_DOWNLOADING
The test for BTUSB_DOWNLOADING must be after adding to the wait queue
and setting the TASK_INTERRUPTIBLE state. Otherwise the flag may get
cleared after we test for it and we end up getting a timeout since
schedule_timeout() waits for the full duration. This patch uses a
wait_on_bit_timeout() + wake_up_bit(). To perform the task both
race-free as well as in a much simpler way.

Since there's no global wait_on_bit_timeout() helper yet (even though
all the building blocks for it are in place) this patch creates a
temporary local btusb copy of it until the global one has made it to
upstream trees.

When many pf_packet listeners are created on a lot of interfaces the
current implementation using global packet type lists scales poorly.
This patch adds per net_device packet type lists to fix this problem.

The patch was originally written by Eric Biederman for linux-2.6.29.

7b4ce694b2 rtnetlink: pass link_net to the newlink handler
When IFLA_LINK_NETNSID is used, the netdevice should be built in this link netns
and moved at the end to another netns (pointed by the socket netns or
IFLA_NET_NS_[PID|FD]).

Existing user of the newlink handler will use the netns argument (src_net) to
find a link netdevice or to check some other information into the link netns.
For example, to find a netdevice, two information are required: an ifindex
(usually from IFLA_LINK) and a netns (this link netns).

Note: when using IFLA_LINK_NETNSID and IFLA_NET_NS_[PID|FD], a user may create a
netdevice that stands in netnsX and with its link part in netnsY, by sending a
rtnl message from netnsZ.

ath3k devices fail to load firmwares on xHCI buses, but work well on

As my testing result, those chips will work on xHCI buses again with

d0ac9eb72b Bluetooth: btusb: Ignore unknown Intel devices with generic descriptor
The Intel Bluetooth devices use the generic USB device/interface class
descriptors that are assigned to Bluetooth H:2 conforming transports.

T:  Bus=01 Lev=01 Prnt=01 Port=01 Cnt=02 Dev#=  3 Spd=12   MxCh= 0
D:  Ver= 2.01 Cls=e0(wlcon) Sub=01 Prot=01 MxPS=64 #Cfgs=  1

However newer chips have a bootloader stage and require firmware to
be loaded before they are functional. To avoid any confusion for the
users, just ignore unknown Intel Bluetooth devices.

All the released Intel Bluetooth devices have an entry in the device
table identifying their setup and support requirements. The advantage
here is that older kernel can be booted with newer devices without
causing any disturbance.

This warning is not critical and has only been placed in the code to
actually catch this exact situation. To avoid triggering it move
the smp_unregister() into hci_dev_do_close() which will now also
take care of remove the SMP channel. It is safe to call this function
since it only remove the channel if it has been previously registered.

c7741d16a5 Bluetooth: Perform a power cycle when receiving hardware error event
When receiving a HCI Hardware Error event, the controller should be
assumed to be non-functional until issuing a HCI Reset command.

The Bluetooth hardware errors are vendor specific and so add a
new hdev->hw_error callback that drivers can provide to run extra
code to handle the hardware error.

After completing the vendor specific error handling perform a full
reset of the Bluetooth stack by closing and re-opening the transport.

592002863a Bluetooth: Fix check for SSP when enabling SC
There's a check in set_secure_conn() that's supposed to ensure that SSP
is enabled before we try to request the controller to enable SC (since
SSP is a pre-requisite for it). However, this check only makes sense for
controllers actually supporting BR/EDR SC. If we have a 4.0 controller
we're only interested in the LE part of SC and should therefore not be
requiring SSP to be enabled. This patch adds an additional condition to
check for lmp_sc_capable(hdev) before requiring SSP to be enabled.

The btusb_disconnect() callback calls hci_unregister_dev() which in turn
calls btusb_close() if the HCI device is powered. The btusb_close()
function in turn will call btusb_free_frags(). It's therefore
unnecessary to have another call to btusb_free_frags() in the

ce6bb9297c Bluetooth: btusb: Handle out of order firmware loading complete event
When loading the Intel firmware it can happen that the firmware loading
complete vendor event arrives before the command complete event for the
last firmware fragment.

< HCI Command: Vendor (0x3f|0x0009) plen 7
        01 02 fc 03 00 00 00
> HCI Event: Vendor (0xff) plen 5
        06 00 00 00 00
> HCI Event: Command Complete (0x0e) plen 4
      Vendor (0x3f|0x0009) ncmd 31
        Status: Success (0x00)

This is mainly caused by the fact that the vendor command and its
command complete event are transported over the bulk endpoints. The
firmware loading complete event however is send over the interrupt
endpoint. So with just bad timing one event arrives before the other.

Currently the code does not account for it. There are precautions for
receiving firmware loading complete event quickly, but not for receiving
it before the command complete.

Introduce an extra flag that tracks when the firmware sending has
completed from the driver point of view and track the completion of
the firmware loading procedure with a different flag. That way the
wakeup can be handled properly.

cda0dd7809 Bluetooth: btusb: Add firmware loading for Intel Snowfield Peak devices
The Intel Snowfield Peak devices do not come with Bluetooth firmware
loaded and thus require a full download of the operational Bluetooth
firmware when the device is connected via USB.

Snowfield Peak devices start with a bootloader mode that only accepts
a very limited set of HCI commands. The supported commands are enough
to identify the hardware and select the right firmware to load.

Previous patches to the btusb driver allow overwriting the handling
for bulk receive endpoint packets and HCI events processing. The
firmware loading makes heavy use of these new internal callbacks.

This patch also introduces additional internal states to track if the
device is in bootloader or operational mode. This allows for correct
feedback about the firmware loading procedure.

         - Kvaser USBcan Rugged ("USBcan Rev B")
