cac68a56e3 ARM: dts: r8a7791: enable to use thermal-zone
This patch enables to use thermal-zone on r8a7791.
This thermal sensor can measure temperature from -40000 to 125000,
but over 117000 can be critical on this chip.
Thus, default critical temperature is now set as 115000 (this driver
is using 5000 steps) (Current critical temperature is using it as
90000, but there is no big reason about it)

And it doesn't check thermal zone periodically (same as current
behavior). You can exchange it by modifying polling-delay[-passive]
property.

You can set trip temp if your kernel has CONFIG_THERMAL_WRITABLE_TRIPS,
but you need to take care to use it, since it will call
orderly_poweroff() it it reaches to the value.

bf456abb9b igb: Add workaround for VLAN tag stripping on 82576
There was a workaround partially implemented for the 82576 that is needed
in order for VLAN tag stripping to function correctly.  The original code
had side effects that would make it so the workaround was active on all
MACs.  I have updated the code so that the workaround is enabled, but
limited to the 82576, or activated if we exceed the available unicast
addresses.

The workaround has a side effect of mirroring all of the traffic outgoing
from the VFs back to the PF.  As such it is not recommended to use the
82576 in promiscuous mode as it will take a performance hit, though this is
now consistent with the performance as seen on the out-of-tree igb driver.

I also limited the scope of the UTA bits all being set to only when the
VMOLR register is enabled.  This should limit the effects of the UTA
register so that we don't pick up any excess traffic unless promiscuous
mode has been enabled on the PF, whereas before the PF would have ended up
in something equivalent to unicast promiscuous mode with VLAN filtering
otherwise.

268f9d33a9 igb: Enable use of "bridge fdb add" to set unicast table entries
This change makes it so that we can use the bridge utility to add a FDB
entry for the PF to an igb port.  By doing this we can enable the VFs to
talk to virtual ports residing on top of the PF.

In addition this should also address issues with MACVLANs trying to reside
on top of the PF as well as they would have had similar issues when added
to the PF with SR-IOV enabled.

a15d92598a igb: Clean-up configuration of VF port VLANs
This patch is meant to clean-up the configuration of the VF port based VLAN
configuration.  The original logic was a bit muddled and had some
undesirable side effects such as VLANs being either completely stripped
from the port or VLANs being left when they shouldn't be.  The idea behind
this code is to avoid any events such as spurious spoof notifications when
we are removing one VLAN tag and replacing it with another.

45693bcb00 igb: Allow asymmetric configuration of MTU versus Rx frame size
Since the igb driver is using page based receive there is no point in
limiting the Rx capabilities of the device.  The driver can receive 9K
jumbo frames at all times.  The only changes needed due to MTU changes are
updates for the FIFO sizes and flow-control watermarks.

Update the maximum frame size to reflect the 9.5K limitation of the
hardware, and replace all instances of max_frame_size with
MAX_JUMBO_FRAME_SIZE when referring to an Rx FIFO or frame.

4e6fd26dcf pinctrl: sirf/atlas7: stop poking around in GPIO internals
This code is poking around in the gpio_chip:s internal structures
to achieve some kind of pin to GPIO mappings.

- It is wrong to poke around in these structs and the pinctrl
  maintainer was stupid to let it pass unnoticed, mea culpa.

- The right interface to use is gpiochip_add_pin_range()

- The code appears unused: the pin control part of the driver
  is not adding any ranges, so we're iterating over an empty
  list. Maybe it is poking around in some other pin controllers
  GPIO ranges, and that's just totally wrong, again use
  gpiochip_add_pin_range() and specify the right pin
  controller.

148ad68b3d gpio: ws16c48: Use devm_request_region
By the time request_region is called in the WinSystems WS16C48 GPIO
driver, a corresponding device structure has already been allocated. The
devm_request_region function should be used to help simplify the cleanup
code and reduce the possible points of failure.
