Currently, the Northwest Logic MIPI-DSI controller host specific code
resides under drm/bridge, but is not a real drm_bridge. It creates a
drm_bridge and adds itself to the drm_encoder that handles this file,
but this is wrong, since it does not implement the drm_bridge_funcs.
The correct way to implement a drm_bridge is to add the drm_bridge and
let other components (another bridge or a drm_encoder) to attach to this
bridge.
Since we are doing this, a new compatible strings can be used for this
driver: "nwl,mipi-dsi".
Since this was used by nwl_dsi-imx.c, update that driver to use this
bridge correctly.
This is needed in order to add support for MIPI-DSI on 8MQ. The IMX_NWL
driver will either add a DSI encoder to DRM, or a DSI bridge.
The encoder will be used by imx-drm-core driver, while the bridge
will be used by MXSFB driver (which creates a simple display pipe).

commit d7119224bf upstream.
The AXP223 PMIC, like the AXP221, does not generate VBUS change
interrupts when N_VBUSEN is used to drive VBUS for the OTG port
on the board.
This was not noticed until recently, as most A23/A33 boards use
a GPIO pin that does not support interrupts for OTG ID detection.
This forces the driver to use polling. However the A33-OlinuXino
uses a pin that does support interrupts, so the driver uses them.
However the VBUS interrupt never fires, and the driver never gets
to update the VBUS status. This results in musb timing out waiting
for VBUS to rise.
This was worked around for the AXP221 by resorting to polling
changes in commit 91d96f06a7 ("phy-sun4i-usb: Add workaround for
missing Vbus det interrupts on A31"). This patch adds the A23 and

commit b7563e2796 upstream.
Stefan Wahren reports a problem with a warning fix that was merged
for v4.15: we had lots of device nodes with a 'phys' property pointing
to a device node that is not compliant with the binding documented in
Documentation/devicetree/bindings/phy/phy-bindings.txt
This generally works because USB HCD drivers that support both the generic
phy subsystem and the older usb-phy subsystem ignore most errors from
phy_get() and related calls and then use the usb-phy driver instead.
However, it turns out that making the usb-nop-xceiv device compatible with
the generic-phy binding changes the phy_get() return code from -EINVAL to
-EPROBE_DEFER, and the dwc2 usb controller driver for bcm2835 now returns
-EPROBE_DEFER from its probe function rather than ignoring the failure,
breaking all USB support on raspberry-pi when CONFIG_GENERIC_PHY is
enabled. The same code is used in the dwc3 driver and the usb_add_hcd()
function, so a reasonable assumption would be that many other platforms
are affected as well.
I have reviewed all the related patches and concluded that "usb-nop-xceiv"
is the only USB phy that is affected by the change, and since it is by far
the most commonly referenced phy, all the other USB phy drivers appear
to be used in ways that are are either safe in DT (they don't use the
'phys' property), or in the driver (they already ignore -EPROBE_DEFER
from generic-phy when usb-phy is available).
To work around the problem, this adds a special case to _of_phy_get()
so we ignore any PHY node that is compatible with "usb-nop-xceiv",
as we know that this can never load no matter how much we defer. In the
future, we might implement a generic-phy driver for "usb-nop-xceiv"
and then remove this workaround.
Since we generally want older kernels to also want to work with the
fixed devicetree files, it would be good to backport the patch into
stable kernels as well (3.13+ are possibly affected), even though they
don't contain any of the patches that may have caused regressions.

Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.
By default all files without license information are under the default
license of the kernel, which is GPL version 2.
Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.
This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.
How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,
Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.
The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.
The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.
Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if <5
lines).
All documentation files were explicitly excluded.
The following heuristics were used to determine which SPDX license
identifiers to apply.
- when both scanners couldn't find any license traces, file was
considered to have no license information in it, and the top level
COPYING file license applied.
For non */uapi/* files that summary was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 11139
and resulted in the first patch in this series.
If that file was a */uapi/* path one, it was "GPL-2.0 WITH
Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 WITH Linux-syscall-note 930
and resulted in the second patch in this series.
- if a file had some form of licensing information in it, and was one
of the */uapi/* ones, it was denoted with the Linux-syscall-note if
any GPL family license was found in the file or had no licensing in
it (per prior point). Results summary:
SPDX license identifier # files
---------------------------------------------------|------
GPL-2.0 WITH Linux-syscall-note 270
GPL-2.0+ WITH Linux-syscall-note 169
((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21
((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17
LGPL-2.1+ WITH Linux-syscall-note 15
GPL-1.0+ WITH Linux-syscall-note 14
((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5
LGPL-2.0+ WITH Linux-syscall-note 4
LGPL-2.1 WITH Linux-syscall-note 3
((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3
((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1
and that resulted in the third patch in this series.
- when the two scanners agreed on the detected license(s), that became
the concluded license(s).
- when there was disagreement between the two scanners (one detected a
license but the other didn't, or they both detected different
licenses) a manual inspection of the file occurred.
- In most cases a manual inspection of the information in the file
resulted in a clear resolution of the license that should apply (and
which scanner probably needed to revisit its heuristics).
- When it was not immediately clear, the license identifier was
confirmed with lawyers working with the Linux Foundation.
- If there was any question as to the appropriate license identifier,
the file was flagged for further research and to be revisited later
in time.
In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.
Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights. The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.
Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.
In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.
Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
- a full scancode scan run, collecting the matched texts, detected
license ids and scores
- reviewing anything where there was a license detected (about 500+
files) to ensure that the applied SPDX license was correct
- reviewing anything where there was no detection but the patch license
was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
SPDX license was correct
This produced a worksheet with 20 files needing minor correction. This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.
These .csv files were then reviewed by Greg. Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected. This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.) Finally Greg ran the script using the .csv files to
generate the patches.

On rk3399-gru-kevin there are some cases where we're seeing AUX CH
failures when trying to do DisplayPort over type C. Problems are
intermittent and don't reproduce all the time. Problems are often
bursty and failures persist for several seconds before going away.
The failure case I focused on is:
* A particular type C to HDMI adapter.
* One orientation (flip mode) of that adapter.
* Easier to see failures when something is plugged into the _other
type C port at the same time.
* Problems reproduce on both type C ports (left and right side).
Ironically problems also stop reproducing when I solder wires onto the
AUX CH signals on a port (even if no scope is connected to the
signals). In this case, problems only stop reproducing on the port
with the wires connected.
From the above it appears that something about the signaling on the
aux channel is marginal and any slight differences can bring us over
the edge to failure.
It turns out that we can fix our problems by just increasing the
voltage swing of the AUX CH, giving us a bunch of extra margin. In DP
up to version 1.2 the voltage swing on the aux channel was specced as
.29 V to 1.38 V. In DP version 1.3 the aux channel voltage was
tightened to be between .29 V and .40 V, but it clarifies that it
really only needs the lower voltage when operating at the highest
speed (HBR3 mode). So right now we are trying to use a voltage that
technically should be valid for all versions of the spec (including
version 1.3 when transmitting at HBR3). That would be great to do if
it worked reliably. ...but it doesn't seem to.
It turns out that if you continue to read through the DP part of the
rk3399 TRM and other parts of the type C PHY spec you'll find out that
while the rk3399 does support DP 1.3, it doesn't support HBR3. The
docs specifically say "RBR, HBR and HBR2 data rates only". Thus there
is actually no requirement to support an AUX CH swing of .4 V.
Even if there is no actual requirement to support the tighter voltage
swing, one could possibly argue that we should support it anyway. The
DP spec clarifies that the lower voltage on the AUX CH will reduce
cross talk in some cases and that seems like it could be beneficial
even at the lower bit rates. At the moment, though, we are seeing
problems with the AUX CH and not on the other lines. Also, checking
another known working and similar laptop shows that the other laptop
runs the AUX channel at a higher voltage.
Other notes:
* Looking at measurements done on the AUX CH we weren't actually
compliant with the DP 1.3 spec anyway. AUX CH peek-to-peek voltage
was measured on rk3399-gru-kevin as .466 V which is > .4 V.
* With this new patch the AUX channel isn't actually 1.0 V, but it has
been confirmed that the signal is better and has more margin. Eye
diagram passes.
* If someone were truly an expert in the Type C PHY and in DisplayPort
signaling they might be able to make things work and keep the
voltage at < .4 V. The Type C PHY seems to have a plethora of
tuning knobs that could almost certainly improve the signal
integrity. Some of these things (like enabling tx_fcm_full_margin)
even seem to fix my problems. However, lacking expertise I can't
say whether this is a better or worse solution. Tightening signals
to give cleaner waveforms can often have adverse affects, like
increasing EMI or adding noise to other signals. I'd rather not
tune things like this without a healthy application of expertise
that I don't have.

On some DP monitors we found that setting the wrong flip state on the
AUX channel could cause the monitor to stop asserting HotPlug Detect
(HPD). Setting the right flip state caused these monitors to start
asserting HotPlug Detect again.
Here's what we believe was happening:
* We'd plug in the monitor and we'd see HPD assert
* We'd quickly see HPD deassert
* The kernel would try to init the type C PHY but would init it in USB
mode (because there was a peripheral there but no HPD)
* Because the kernel never set the flip mode properly we'd never see
the HPD come back.
With this change, we'll still see HPD disappear (we don't think
there's anything we can do about that), but then it will come back.
Overall we can say that it's sane to set the AUX channel flip state
even when HPD is not asserted.
NOTE: to make this change possible, I needed to do a bit of cleanup to
the tcphy_dp_aux_calibration() function so that it doesn't ever
clobber the FLIP state. This made it very obvious that a line of code
documented as "setting bit 12" also did a bunch of other magic,
undocumented stuff. For now I'll just break out the bits and add a
comment that this is black magic and we'll try to document
tcphy_dp_aux_calibration() better in a future CL.
ALSO NOTE: the old function used to write a bunch of hardcoded
values in _some_ cases instead of doing a read-modify-write. One
could possibly assert that these could have had (beneficial) side
effects and thus with this new code (which always does
read-modify-write) we could have a bug. We shouldn't need to worry,
though, since in the old code tcphy_dp_aux_calibration() was always
called following the de-assertion of "reset" the the type C PHY.
...so the type C PHY was always in default state. TX_ANA_CTRL_REG_1
is documented to be 0x0 after reset. This was also confirmed by
printk.

Here is the big char/misc driver update for 4.14-rc1.
Lots of different stuff in here, it's been an active development cycle
for some reason. Highlights are:
- updated binder driver, this brings binder up to date with what
shipped in the Android O release, plus some more changes that
happened since then that are in the Android development trees.
- coresight updates and fixes
- mux driver file renames to be a bit "nicer"
- intel_th driver updates
- normal set of hyper-v updates and changes
- small fpga subsystem and driver updates
- lots of const code changes all over the driver trees
- extcon driver updates
- fmc driver subsystem upadates
- w1 subsystem minor reworks and new features and drivers added
- spmi driver updates
Plus a smattering of other minor driver updates and fixes.
All of these have been in linux-next with no reported issues for a
while.

On the CP110 unit, which can be found on various Marvell platforms such
as the 7k and 8k (currently), a comphy (common PHYs) hardware block can
be found. This block provides a number of PHYs which can be used in
various modes by other controllers (network, SATA ...). These common
PHYs must be configured for the controllers using them to work correctly
either at boot time, or when the system runs to switch the mode used.
This patch adds a driver for this comphy hardware block, providing
callbacks for the its PHYs so that consumers can configure the modes
used.
As of this commit, two modes are supported by the comphy driver: sgmii
and 10gkr.

Reconstruct the whole driver to support per-lane PHYs. Note that we could
also support the legacy PHY if you don't provide argument to
rockchip_pcie_phy_of_xlate().

Detailed description for this pull request:
1. Add new 'extcon-usbc-cros-ec.c' driver
- ChromeOS Embedded Controller extcon driver supports
the detection of the Display Port (EXTCON_DISP_DP)
through USB C-type and contol it.
2. Update extcon core
- Modify the description for both functions and structures
in order to improve the readability and give the more correct
guide about the role of functions because there are different
explanation even if the same arguments.
- Keep the indentation with tab instead of space
- Remove the following deprecated extcon API. The deprecated API
are exchanged on all of linux tree.
: extcon_get_cable_state_() -> extcon_get_state()
: extcon_set_cable_state_() -> extcon_set_state_sync()
3. Include the two immutable branch as following:
- ib-extcon-mfd-4.14 for the 'extcon-ubsc-cros-ec.c' driver
because the patches of 'extcon-ubsc-cros-ec.c' touch the MFD directory.
- ib-extcon-usb-phy-4.14 for removing the deprecated extcon API
because the usb/phy driver usese the deprecated extcon API.
So, this immutable branch alters the extcon API and then
remove them from extcon.
4. Fix minor issue of extcon driver
- Fix the MHL detection on extcon-max77693.c
- Convert to using %pOF instead of full_name on extcon.c
- Add 'const' kerywod for acpi_device_id on extcon-intel-int3496.c

Casting between an 'int' and a pointer causes a warning on
64-bit architectures in compile-testing this driver:
drivers/phy/ralink/phy-ralink-usb.c: In function 'ralink_usb_phy_probe':
drivers/phy/ralink/phy-ralink-usb.c:195:13: error: cast from pointer to
integer of different size [-Werror=pointer-to-int-cast]
This changes the code to cast to uintptr_t instead. This is
guaranteed to do what we want on all architectures and avoids
the warning.
