This patch adds platform init/exit functions and modifications to support
suspend/resume for the Altera Cyclone 5 SOC Ethernet controller. The platform
exit function puts the controller into reset using the socfpga reset
controller driver. The platform init function sets up the Synopsys mac by
first making sure the Ethernet controller is held in reset, programming the
phy mode through external support logic, then deasserts reset through
the socfpga reset manager driver.

In the event flow, we currently pass only a port number in the
void *data argument. Rather than pass a pointer to the event handlers,
we should use an "unsigned long" parameter, and pass the port number
value directly.
In the future, if necessary for some events, we can use the unsigned long
parameter to pass a pointer.

In preparation for a new mlx5 device which is VPI (i.e., ports can be
either IB or ETH), move the pci device functionality from mlx5_ib
to mlx5_core.
This involves the following changes:
1. Move mlx5_core_dev struct out of mlx5_ib_dev. mlx5_core_dev
is now an independent structure maintained by mlx5_core.
mlx5_ib_dev now has a pointer to that struct.
This requires changing a lot of places where the core_dev
struct was accessed via mlx5_ib_dev (now, this needs to
be a pointer dereference).
2. All PCI initializations are now done in mlx5_core. Thus,
it is now mlx5_core which does pci_register_device (and not
mlx5_ib, as was previously).
3. mlx5_ib now registers itself with mlx5_core as an "interface"
driver. This is very similar to the mechanism employed for
the mlx4 (ConnectX) driver. Once the HCA is initialized
(by mlx5_core), it invokes the interface drivers to do
their initializations.
4. There is a new event handler which the core registers:
mlx5_core_event(). This event handler invokes the
event handlers registered by the interfaces.

This commit is similar to commit 4d12bc63ab5e ("net: mvneta: fix
operation in 10 Mbit/s mode"), but this time for the mvpp2 driver. The
driver was properly taking into account the 1 Gbit/s and 100 Mbit/s
speeds, but not the 10 Mbit/s, which was handled as 100
Mbit/s. However, the MVPP2_GMAC_CONFIG_MII_SPEED bit in the
MVPP2_GMAC_AUTONEG_CONFIG register must remain cleared to allow 10
Mbit/s operation. This commit therefore fixes 10 Mbit/s operation.

__iowrite64_copy() isn't quite the same as efx_memcpy_64(), but
it looks close enough:
- The length is in units of qwords not bytes
- It never byte-swaps, but that doesn't make a difference now as PIO
is only enabled for x86_64
- It doesn't include any memory barriers, but that's OK as there is a
barrier just before pushing the doorbell
- mlx4_en uses it for the same purpose

Commit 87aa9f9c61ad ("net: phy: consolidate PHY reset in phy_init_hw()")
moved the call to phy_scan_fixups() in phy_init_hw() after a software
reset is performed.
By the time phy_init_hw() is called in phy_device_register(), no driver
has been bound to this PHY yet, so all the checks in phy_init_hw()
against the PHY driver and the PHY driver's config_init function will
return 0. We will therefore never call phy_scan_fixups() as we should.
Fix this by calling phy_scan_fixups() and check for its return value to
restore the intended functionality.
This broke PHY drivers which do register an early PHY fixup callback to
intercept the PHY probing and do things like changing the 32-bits unique
PHY identifier when a pseudo-PHY address has been used, as well as
board-specific PHY fixups that need to be applied during driver probe
time.

Hardware timestamps can be exposed to userspace in raw hardware format
(hwtstamp) as well as converted to system time (syststamp). The second
variant is deprecated and only implemented by this driver.
The preferred method of hardware timestamp generation is to combine
hwtstamp with a device PTP clock. Octeon has its own PTP library
that relies on a shared memory interface to the PTP clock device.

Please pull this batch of updates intended for the 3.17 stream!
For the mac80211 bits, Johannes says:
"We have a lot of TDLS patches, among them a fix that should make hwsim
tests happy again. The rest, this time, is mostly small fixes."
For the Bluetooth bits, Gustavo says:
"Some more patches for 3.17. The most important change here is the move of
the 6lowpan code to net/6lowpan. It has been agreed with Davem that this
change will go through the bluetooth tree. The rest are mostly clean up and
fixes."
and,
"Here follows some more patches for 3.17. These are mostly fixes to what
we've sent to you before for next merge window."
For the iwlwifi bits, Emmanuel says:
"I have the usual amount of BT Coex stuff. Arik continues to work
on TDLS and Ariej contributes a few things for HS2.0. I added a few
more things to the firmware debugging infrastructure. Eran fixes a
small bug - pretty normal content."
And for the Atheros bits, Kalle says:
"For ath6kl me and Jessica added support for ar6004 hw3.0, our latest
version of ar6004.
For ath10k Janusz added a printout so that it's easier to check what
ath10k kconfig options are enabled. He also added a debugfs file to
configure maximum amsdu and ampdu values. Also we had few fixes as
usual."
On top of that is the usual large batch of various driver updates --
brcmfmac, mwifiex, the TI drivers, and wil6210 all get some action.
Rafał has also been very busy with b43 and related updates.
Also, I pulled the wireless tree into this in order to resolve a
merge conflict...
P.S. The change to fs/compat_ioctl.c reflects a name change in a
Bluetooth header file...

The sunvnet driver doesn't check whether or not a port is connected when
transmitting packets, which results in failures if a port fails to connect
(e.g., due to a version mismatch). The original code also assumes
unnecessarily that the first port is up and a switch, even though there is
a flag for switch ports.
This patch only matches a port if it is connected, and otherwise uses the
switch_port flag to send the packet to a switch port that is up.

Adding a function, and associated calls, to flush writes to (read) the LPIC

EEE and 100M link) when Runtime PM is enabled.

The process of shutting down the system causes a call to the close PM
callback. The reset in close causes a loss of link, and the resultant
LSC interrupt causes the Runtime PM idle callback to be called. The
check for link (while link is down) in the idle callback is wiping the
information about the EEE ability of the link partner. The information is
still gone when the PHY is powered back up in the shutdown flow. This
causes EEE in S5 to fail when Runtime PM is active.
Save the link partner's EEE ability in the idle callback so that a Runtime
PM event will not cause a loss of this information.

On I217 and newer hardware, EEE is enabled in the PHY by the software
when link is up and disabled by the hardware when link is lost.
To enable EEE in Sx (When both ends of the link support, and are enabled
for, EEE and 100Mbps), we need to disable LPLU and configure the PHY to
automatically enable EEE when link is up, since there will be no software
to complete the task.
To configure this in the PHY, the Auto Enable LPI bit in the Low Power
Idle GPIO Control register must be set. For normal operation in S0, this
bit must be cleared.

if getting the REGSMP bit in the IXGBE_SW_FW_SYNC register
