Make sure to deregister and free any fixed-link phy registered during
probe on probe errors and on driver unbind by adding a new glue helper
function.
Drop the of-node reference taken in the same path also on late probe
errors (and not just on driver unbind) by moving the put from
stmmac_dvr_remove() to the new helper.

In the case of IPIP and SIT tunnel frames the outer transport header
offset is actually set to the same offset as the inner transport header.
This results in the lco_csum call not doing any checksum computation over
the inner IPv4/v6 header data.
In order to account for that I am updating the code so that we determine
the location to start the checksum ourselves based on the location of the
IPv4 header and the length.

Many drivers (21 to be exact) create connectors that are always
connected (for instance to an LVDS or DSI panel). Instead of forcing
them to implement a dummy .detect() handler, make the callback optional
and consider the connector as always connected in that case.

This adds support for PEAK-System PCAN-USB X6 USB to CAN interface.
The CAN FD adapter PCAN-USB X6 allows the connection of up to 6 CAN FD
or CAN networks to a computer via USB. The interface is installed in an
aluminum profile casing and is shipped in versions with D-Sub connectors
or M12 circular connectors.
The PCAN-USB X6 registers in the USB sub-system as if 3x PCAN-USB-Pro FD
adapters were plugged. So, this patch:
- updates the PEAK_USB entry of the corresponding Kconfig file
- defines and adds the device id. of the PCAN-USB X6 (0x0014) into the
table of supported device ids
- defines and adds the new software structure implementing the PCAN-USB X6,
which is obviously a clone of the software structure implementing the
PCAN-USB Pro FD.

This fixes the bitimings fields ranges supported by all the CAN-FD USB
interfaces of the PEAK-System CAN-FD adapters.
Very first development versions of the IP core API defined smaller TSGEx
and SJW fields for both nominal and data bittimings records than the
production versions. This patch fixes them by enlarging their sizes to
the actual values:
field: old size: fixed size:
nominal TSGEG1 6 8
nominal TSGEG2 4 7
nominal SJW 4 7
data TSGEG1 4 5
data TSGEG2 3 4
data SJW 2 4
Note that this has no other consequences than offering larger choice to
bitrate encoding.

commit 202b52b7fbf7 ("drm: Track drm_mm nodes with an interval tree")
introduced a requirement that the special drm_mm.head_node was
initialised and marked as not being allocated. It is a very special node
that has no side but has a hole that represents the drm_mm address
space, and holds the list of nodes. Since it is not a real node, it is
not part of the node rbtree and we detect this as it being unallocated.
This presumed that drm_mm_init() was initialising it to zero. It happens
that i915 kzallocs its objects and so it was accidentally setting it,
but for generic use we cannot make that assumption.

The Amlogic Meson Display controller is composed of several components :

M |-------|______|----|____________| |________________| | |
___|__________________________________________________________|_______________|
VIU: Video Input Unit
---------------------
The Video Input Unit is in charge of the pixel scanout from the DDR memory.
It fetches the frames addresses, stride and parameters from the "Canvas" memory.
This part is also in charge of the CSC (Colorspace Conversion).
It can handle 2 OSD Planes and 2 Video Planes.
VPP: Video Post Processing
--------------------------
The Video Post Processing is in charge of the scaling and blending of the
various planes into a single pixel stream.
There is a special "pre-blending" used by the video planes with a dedicated
scaler and a "post-blending" to merge with the OSD Planes.
The OSD planes also have a dedicated scaler for one of the OSD.
VENC: Video Encoders
--------------------
The VENC is composed of the multiple pixel encoders :
- ENCI : Interlace Video encoder for CVBS and Interlace HDMI
- ENCP : Progressive Video Encoder for HDMI
- ENCL : LCD LVDS Encoder
The VENC Unit gets a Pixel Clocks (VCLK) from a dedicated HDMI PLL and clock
tree and provides the scanout clock to the VPP and VIU.
The ENCI is connected to a single VDAC for Composite Output.
The ENCI and ENCP are connected to an on-chip HDMI Transceiver.
This driver is a DRM/KMS driver using the following DRM components :
- GEM-CMA
- PRIME-CMA
- Atomic Modesetting
- FBDev-CMA
For the following SoCs :
- GXBB Family (S905)
- GXL Family (S905X, S905D)
- GXM Family (S912)
The current driver only supports the CVBS PAL/NTSC output modes, but the
CRTC/Planes management should support bigger modes.
But Advanced Colorspace Conversion, Scaling and HDMI Modes will be added in
a second time.
The Device Tree bindings makes use of the endpoints video interface definitions
to connect to the optional CVBS and in the future the HDMI Connector nodes.
HDMI Support is planned for a next release.

The zram hot removal code calls idr_remove() even when zram_remove()
returns an error (typically -EBUSY). This results in a leftover at the
device release, eventually leading to a crash when the module is
reloaded.
As described in the bug report below, the following procedure would
cause an Oops with zram:
- provision three zram devices via modprobe zram num_devices=3
- configure a size for each device
+ echo "1G" > /sys/block/$zram_name/disksize
- mkfs and mount zram0 only
- attempt to hot remove all three devices
+ echo 2 > /sys/class/zram-control/hot_remove
+ echo 1 > /sys/class/zram-control/hot_remove
+ echo 0 > /sys/class/zram-control/hot_remove
- zram0 removal fails with EBUSY, as expected
- unmount zram0
- try zram0 hot remove again
+ echo 0 > /sys/class/zram-control/hot_remove
- fails with ENODEV (unexpected)
- unload zram kernel module
+ completes successfully
- zram0 device node still exists
- attempt to mount /dev/zram0
+ mount command is killed
+ following BUG is encountered

drm-next
On the userspace side, all the basics are working, and most of glmark2
is working. I've been working through deqp, and I've got a couple more
things to fix (but we've gone from 70% to 80+% pass in last day, and
current deqp run that is going should pick up another 5-10%). I expect
to push the mesa patches today or tomorrow.
There are a couple more a5xx related patches to take the gpu out of
secure mode (for the devices that come up in secure mode, like the hw
I have), but those depend on an scm patch that would come in through
another tree. If that can land in the next day or two, there might
be a second late pull request for drm/msm.
In addition to the new-shiny, there have also been a lot of overlay/
plane related fixes for issues found using drm-hwc2 (in the process of
testing/debugging the atomic/kms fence patches), resulting in rework
to assign hwpipes to kms planes dynamically (as part of global atomic
state) and also handling SMP (fifo) block allocation atomically as
part of the ->atomic_check() step. All those patches should also help
out atomic weston (when those patches eventually land).

We trigger uarg->callback() immediately after we decide do datacopy
even if caller want to do zerocopy. This will cause the callback
(vhost_net_zerocopy_callback) decrease the refcount. But when we meet
an error afterwards, the error handling in vhost handle_tx() will try
to decrease it again. This is wrong and fix this by delay the
uarg->callback() until we're sure there's no errors.

netif_set_real_num_tx/rx_queues() are required to be called with rtnl_lock
taken, otherwise ASSERT_RTNL() warning will be triggered - which happens
now during System resume from suspend:
cpsw_resume()
|- cpsw_ndo_open()
|- netif_set_real_num_tx/rx_queues()
|- ASSERT_RTNL();
Hence, fix it by surrounding cpsw_ndo_open() by rtnl_lock/unlock() calls.

Execution 'ethtool -S' on fec device that is down causes OOPS on Vybrid
board:
Unhandled fault: external abort on non-linefetch (0x1008) at 0xe0898200
pgd = ddecc000
[e0898200] *pgd=9e406811, *pte=400d1653, *ppte=400d1453
Internal error: : 1008 [#1] SMP ARM
...
Reason of OOPS is that fec_enet_get_ethtool_stats() accesses fec
registers while IPG clock is stopped by PM.
Fix that by caching statistics in fec_enet_private. Cache is initialized
at device probe time, and updated at statistics request time if device
is up, and also just before turning device off on down path.
Additional locking is not needed, since cached statistics is accessed
either before device is registered, or under rtnl_lock().

The DT binding for tildc is not consistent with the driver code: there
are two options - 'max-width' and 'max-pixelclock' specified in the
documentation which are parsed as 'ti,max-width' and
'ti,max-pixelclock' respectively.
Make the driver code consistent with the binding.

Configure video mode to HW in enable() call back. There is no reason
to do it before that. This makes PM functions way easier because there
is no HW context to save when screen is for instance blanked. This
patch removes mode_set_nofb() call back from tilcdc.

Adds drm bride support for attaching drm bridge drivers to tilcdc. The
decision whether a video port leads to an external encoder or bridge
is made simply based on remote device's compatible string. The code
has been tested with BeagleBone-Black with and without BeagleBone
DVI-D Cape Rev A3 using ti-tfp410 driver.

Add very basic ti-tfp410 DVI transmitter driver. The only feature
separating this from a completely dummy bridge is the EDID read
support trough DDC I2C. Even that functionality should be in a
separate generic connector driver. However, because of missing DRM
infrastructure support the connector is implemented within the bridge
driver. Some tfp410 HW specific features may be added later if needed,
because there is a set of registers behind i2c if it is connected.
This implementation is tested against my new tilcdc bridge support
and it works with BeagleBone DVI-D Cape Rev A3. A DT binding document
is also updated.

Recover from sync lost error flood by resetting the LCDC instead of
turning off the SYNC_LOST error IRQ. When LCDC starves on limited
memory bandwidth it may sometimes result an error situation when the
picture may have shifted couple of pixels to right and SYNC_LOST
interrupt is generated on every frame. LCDC main reset recovers from
this situation and causes a brief blanking on the screen.
