5a7a59d254 brcmfmac: limit hex dump on fwil.
When debug is turned on for fwil then the whole data buffer is
dumped. In some cases this gives excessive amount of debug. With
this patch the dumps are limited to 64 bytes.

756a670052 brcmfmac: sdio module load fix.
On sdio module unload followed by load (without removing the
device) the access window should be moved back to enumeration
space. Force this by removing initialisation of sbwad during
probe.

5b3c183272 brcmfmac: avoid usage of func->card->dev in sdio probe.
brcmf_ops_sdio_probe used the private_date func->card->dev to
store device data of brcmfmac sdio. This is not a good place to
store the data. Use dev of func and use func->card->sdio_func
to group the functions the driver is using.

3e0a97e150 brcmfmac: restructure handling of IF event
The IF event need special care. It can be either an ADD, DEL, or
CHANGE. For an ADD we need to call brcmf_add_if() before the
event handler call. Upon a DEL we need to call brcmf_del_if()
after the event handler call. CHANGE does not require special
attention.

state, the HW is stuck at NF calibration which prevents tx output.
The root cause is wrong peak detector offset calibrated by HW. To
resolve this issue, peak detector calibration is done manually by SW
for AR9462 and AR9565.

f95275c48b mwl8k: Send BASTREAM firmware commands per vif
The firmware supports 8 macid's corresponding to 8 BSS that can be
created in an MBSS environment. Currently, BASTREAM commands were always
sent with macid 0. This macid is used to configure the hardware ampdu
registers with appropriate BSS address in an MBSS environment.
This mac address is used by the hardware for various ampdu related requirements
e.g. source address in BAR generation, BA interpretation e.t.c.
Using invalid macid results in this mac address not getting appropriately
configured in the hardware which results in issues during ampdu traffic.

Fix this by sending the BASTREAM commands with appropriate macid.

call in wl12xx_chip_wakeup, the containing function just returns, but on
the failure of the call in wl12xx_get_hw_info, the containing function
calls wl1271_power_off.  This does not seem necessary, because if
wl12xx_set_power_on has set the power on and then fails, it has already
turned the power off.

c5aff18204 net: mvneta: driver for Marvell Armada 370/XP network unit
This patch contains a new network driver for the network unit of the
ARM Marvell Armada 370 and the Armada XP. Both SoCs use the PJ4B
processor, a Marvell-developed ARM core that implements the ARMv7
instruction set.

Compared to previous ARM Marvell SoCs (Kirkwood, Orion, Discovery),
the network unit in Armada 370 and Armada XP is highly different. This
is the reason why this new 'mvneta' driver is needed, while the older
ARM Marvell SoCs use the 'mv643xx_eth' driver.

Here is an overview of the most important hardware changes that
require a new, specific, driver for the network unit of Armada 370/XP:

 - The new network unit has a completely different design and layout
   for the RX and TX descriptors. They are now organized as a simple
   array (each RX and TX queue has base address and size of this
   array) rather than a linked list as in the old SoCs.

 - The new network unit has a different RXQ and TXQ management: this
   management is done using special read/write counter registers,
   while in the Old SocS, it was done using the Ownership bit in RX
   and TX descriptors.

 - The new network unit has different interrupt registers

 - The new network unit way of cleaning of interrupts is not done by
   writing to the cause register, but by updating per-queue counters

 - The new network unit has different GMAC registers (link, speed,
   duplex configuration) and different WRR registers.

 - The new network unit has lots of new units like PnC (Parser and
   Classifier), PMT, BM (Memory Buffer Management), xPON, and more.

The driver proposed in the current patch only handles the basic
features. Additional hardware features will progressively be supported
as needed.

This code has originally been written by Rami Rosen
<rosenr@marvell.com>, and then reviewed and cleaned up by Thomas
Petazzoni <thomas.petazzoni@free-electrons.com>.

fc8f5aded1 net: mvmdio: new Marvell MDIO driver
This patch adds a separate driver for the MDIO interface of the
Marvell Ethernet controllers. There are two reasons to have a separate
driver rather than including it inside the MAC driver itself:

 *) The MDIO interface is shared by all Ethernet ports, so a driver
    must guarantee non-concurrent accesses to this MDIO interface. The
    most logical way is to have a separate driver that handles this
    single MDIO interface, used by all Ethernet ports.

 *) The MDIO interface is the same between the existing mv643xx_eth
    driver and the new mvneta driver. Even though it is for now only
    used by the mvneta driver, it will in the future be used by the
    mv643xx_eth driver as well.

ff7e68670c ath6kl: support NL80211_USER_REG_HINT_CELL_BASE events
As ath6kl firmware can't do intersections the driver should only listen
to regdom changes from cellular base stations, all other requests need to
be refused.

6fc4adca6c tilegx: request_irq with a non-null device name
This patch simply makes the tilegx net driver call request_irq with a
non-null name. It makes the output in /proc/interrupts more obvious, but
also helps tools that don't expect to find null there.

191c5f1027 TTY: call tty_port_destroy in the rest of drivers
After commit "TTY: move tty buffers to tty_port", the tty buffers are
not freed in some drivers. This is because tty_port_destructor is not
called whenever a tty_port is freed. This was an assumption I counted
with but was unfortunately untrue. So fix the drivers to fulfil this
assumption.

To be sure, the TTY buffers (and later some stuff) are gone along with
the tty_port, we have to call tty_port_destroy at tear-down places.
This is mostly where the structure containing a tty_port is freed.
This patch does exactly that -- put tty_port_destroy at those places.

Marc Kleine-Budde says:

====================
this pull request is for net-next, for the v3.8 release cycle. Muhammad
Ghias added support another board to the plx_pci sja1000 driver.
Matthias Fuchs improved the esd_usb2 driver with listen-only mode and
CAN-USB/Micro support. Andreas Larsson contributed a driver for the
GRHCAN CAN IP-Core

4223dbffed net: phy: smsc: Re-enable EDPD mode for LAN87xx
This patch re-enables Energy Detect Power Down (EDPD) mode for the
LAN8710/LAN8720.  EDPD mode was disabled in a previous commit,
(b629820d18), because it was causing the
PHY to not be able to detect a link when cold started without a cable
connected.

The LAN8710/LAN8720 requires a minimum of 2 link pulses within 64ms of
each other in order to set the ENERGYON bit and exit EDPD mode.  If a
link partner does send the pulses within this interval, the PHY will
remained powered down.

This workaround will manually toggle the PHY on/off upon calls to
read_status in order to generate link test pulses if the link is down.
If a link partner is present, it will respond to the pulses, which will
cause the ENERGYON bit to be set and will cause the EDPD mode to be
exited.
