b466c1dd73 HID: Add vendor specific usage pages for Logitech G920
The Logitech G920 uses a couple of vendor specific usage pages,
which results in incorrect number of axis/buttons being detected.

7bfd2927ad HID: hid-logitech-hidpp: Add basic support for Logitech G920
This patch adds basic support for the Logitech G920 wheel when in HID
mode. This wheel 'speaks' the HID++ protocol, and therefor is driven
with hid-logitech-hidpp.

At this stage the driver only shows that it can communicate with the
wheel by outputting the name discovered over HID++.

The normal HID functions work to give input functionality using
joystick/event interface.

Note: in 'hidpp_probe()' we have to start the hardware to get packets
flowing, the same might apply in future for other devices which don't
use the unifying protocol.

Pass a **skb to ipvlan_rcv_frame so that if skb_share_check returns a
new skb, we actually use it during further processing.

It's safe to ignore the new skb in the ipvlan_xmit_* functions, because
they call ipvlan_rcv_frame with local == true, so that dev_forward_skb
is called and always takes ownership of the skb.

6c606fa32c via-velocity: unconditionally drop frames with bad l2 length
By default the driver allowed incorrect frames to be received. What is
worse the code does not handle very short frames correctly. The FCS
length is unconditionally subtracted, and the underflow can cause
skb_put to be called with large number after implicit cast to unsigned.
And indeed, an skb_over_panic() was observed with via-velocity.

This removes the module parameter as it does not work in it's
current state, and should be implemented via NETIF_F_RXALL if needed.

c3f45d322c dl2k: Add support for IP1000A-based cards
Add support for IP1000A chips to dl2k driver.
IP1000A chip looks like a TC9020 with integrated PHY.

This allows IP1000A chips to work reliably because the ipg driver is
buggy - it loses packets under load and then completely stops
transmitting data.

Tested with Asus NX1101 v2.0 at 10, 100 and 1000Mbps:
vendor=0x13f0 device=0x1023 (rev 0x41)
subsystem vendor=0x1043 device=0x8180

MAC address registers access needed to be changed from 8-bit to 16-bit
because 8-bit does not work on IP1000A. 8-bit access is not even
allowed in the TC9020 datasheet (although it worked). 16-bit access
works on both.

Tested that it does not break D-Link DGE-550T (DL-2000 chip, probably
a rebranded TC9020):
vendor=0x1186 device=0x4000 (rev 0x0c)
subsystem vendor=0x1186 device=0x4000

cd998ecd2f net: smsc911x: Reset PHY during initialization
On certain hardware after software reboot the chip may get stuck and fail
to reinitialize during reset. This can be fixed by ensuring that PHY is
reset too.

Old PHY resetting method required operational MDIO interface, therefore
the chip should have been already set up. In order to be able to function
during probe, it is changed to use PMT_CTRL register.

The problem could be observed on SMDK5410 board.

cef03d7e66 hwmon: (scpi) skip unsupported sensors properly
Currently it's assumed that firmware exports only the class of sensors
supported by the driver. However with newer firmware or SCPI protocol
revision, support for newer classes of sensors can be present.

The driver fails to probe with the following warning if an unsupported
class of sensor is encountered in the firmware.

sysfs: cannot create duplicate filename
	'/devices/platform/scpi/scpi:sensors/hwmon/hwmon0/'
------------[ cut here ]------------
WARNING: at fs/sysfs/dir.c:31
Modules linked in:

CPU: 0 PID: 6 Comm: kworker/u12:0 Not tainted 4.3.0-rc7 #137

Workqueue: deferwq deferred_probe_work_func
PC is at sysfs_warn_dup+0x54/0x78
LR is at sysfs_warn_dup+0x54/0x78

This patch fixes the above issue by skipping through the unsupported
class of SCPI sensors.

d42d5b6f72 hwmon: (scpi) add thermal-of dependency
The newly added scpi thermal support is broken when the scpi driver
is built-in but the thermal driver is a loadable module:

drivers/built-in.o: In function `scpi_hwmon_probe':
(.text+0x444d70): undefined reference to `thermal_zone_of_sensor_unregister'
(.text+0x444d94): undefined reference to `thermal_zone_of_sensor_register'
drivers/built-in.o: In function `scpi_hwmon_remove':
(text+0x444e6c): undefined reference to `thermal_zone_of_sensor_unregister'

This uses the same Kconfig trick that we have in a couple of other
drivers already to ensure we can only select the driver in valid
configurations when either THERMAL_OF is disabled, or when with a
dependency on CONFIG_THERMAL that can force SCPI to be a loadable
module in the case I was hitting.
