drm/bridge/synopsys: dw-hdmi: don't clobber drvdata
dw_hdmi shouldn't set drvdata since some drivers might need to store
it's own data there. Rework dw_hdmi in a way to return struct dw_hdmi
instead to store it in drvdata. This way drivers are responsible to
store and pass structure when needed.

Idea was taken from the following commit:
8242ecbd59 ("drm/bridge/synopsys: stop clobbering drvdata")

1c16a9ce01 drm/rockchip: lvds: Explicitly include pinctrl headers
The Rockchip LVDS driver fails to build after commit 23c35f48f5
("pinctrl: remove include file from <linux/device.h>") because it relies
on the pinctrl/consumer.h and pinctrl/devinfo.h being pulled in by the
device.h header implicitly.

Include these headers explicitly to avoid the build failure.

c2d6e243ff drm/rockchip: Use drm_mode_get_hv_timing() to populate plane clip rectangle
Use drm_mode_get_hv_timing() to fill out the plane clip rectangle.

Note that this replaces crtc_state->adjusted_mode usage with
crtc_state->mode. The latter is the correct choice since that's the
mode the user provided and it matches the plane crtc coordinates
the user also provided.

Once everyone agrees on this we can move the clip handling into
drm_atomic_helper_check_plane_state().

f1781e9bb2 drm/edid: Allow HDMI infoframe without VIC or S3D
Appedix F of HDMI 2.0 says that some HDMI sink may fail to switch from
3D to 2D mode in a timely fashion if the source simply stops sending the
HDMI infoframe. The suggested workaround is to keep sending the
infoframe even when strictly not necessary (ie. no VIC and no S3D).
HDMI 1.4 does allow for this behaviour, stating that sending the
infoframe is optional in this case.

The infoframe was first specified in HDMI 1.4, so in theory sinks
predating that may not appreciate us sending an uknown infoframe
their way. To avoid regressions let's try to determine if the sink
supports the infoframe or not. Unfortunately there's no direct way
to do that, so instead we'll just check if we managed to parse any
HDMI 1.4 4k or stereo modes from the EDID, and if so we assume the
sink will accept the infoframe. Also if the EDID contains the HDMI
2.0 HDMI Forum VSDB we can assume the sink is prepared to receive
the infoframe.

v2: Fix getting has_hdmi_infoframe from display_info
    Always fail constructing the infoframe if the display
    possibly can't handle it

e99e88a9d2 treewide: setup_timer() -> timer_setup()
This converts all remaining cases of the old setup_timer() API into using
timer_setup(), where the callback argument is the structure already
holding the struct timer_list. These should have no behavioral changes,
since they just change which pointer is passed into the callback with
the same available pointers after conversion. It handles the following
examples, in addition to some other variations.

Casting from unsigned long:

    void my_callback(unsigned long data)
    {
        struct something *ptr = (struct something *)data;
    ...
    }
    ...
    setup_timer(&ptr->my_timer, my_callback, ptr);

and forced object casts:

    void my_callback(struct something *ptr)
    {
    ...
    }
    ...
    setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr);

become:

    void my_callback(struct timer_list *t)
    {
        struct something *ptr = from_timer(ptr, t, my_timer);
    ...
    }
    ...
    timer_setup(&ptr->my_timer, my_callback, 0);

Direct function assignments:

    void my_callback(unsigned long data)
    {
        struct something *ptr = (struct something *)data;
    ...
    }
    ...
    ptr->my_timer.function = my_callback;

have a temporary cast added, along with converting the args:

    void my_callback(struct timer_list *t)
    {
        struct something *ptr = from_timer(ptr, t, my_timer);
    ...
    }
    ...
    ptr->my_timer.function = (TIMER_FUNC_TYPE)my_callback;

And finally, callbacks without a data assignment:

    void my_callback(unsigned long data)
    {
    ...
    }
    ...
    setup_timer(&ptr->my_timer, my_callback, 0);

have their argument renamed to verify they're unused during conversion:

    void my_callback(struct timer_list *unused)
    {
    ...
    }
    ...
    timer_setup(&ptr->my_timer, my_callback, 0);

The conversion is done with the following Coccinelle script:

spatch --very-quiet --all-includes --include-headers \
	-I ./arch/x86/include -I ./arch/x86/include/generated \
	-I ./include -I ./arch/x86/include/uapi \

drm_plane_helper_check_update() isn't a transitional helper, so let's
rename it to drm_atomic_helper_check_plane_state() and move it into
drm_atomic_helper.c.

10b47ee02d drm: Check crtc_state->enable rather than crtc->enabled in drm_plane_helper_check_state()
drm_plane_helper_check_state() is supposed to do things the atomic way,
so it should not be inspecting crtc->enabled. Rather we should be
looking at crtc_state->enable.

We have a slight complication due to drm_plane_helper_check_update()
reusing drm_plane_helper_check_state() for non-atomic drivers. Thus
we'll have to pass the crtc_state in manally and construct a fake
crtc_state in drm_plane_helper_check_update().

d471ed04b4 drm/drivers: drop redundant drm_edid_to_eld() calls
drm_add_edid_modes() now fills in the ELD automatically, so the calls to
drm_edid_to_eld() are redundant. Remove them.

All the other places are obvious, but nv50 has detached
drm_edid_to_eld() from the drm_add_edid_modes() call.

30cfcf0166 drm/rockchip: add CONFIG_OF dependency for lvds
Build-testing on randconfig kernels revealed a dependency in the
newly added lvds sub-driver:

drivers/gpu/drm/rockchip/rockchip_lvds.c: In function 'rockchip_lvds_bind':
drivers/gpu/drm/rockchip/rockchip_lvds.c:380:24: error: 'struct drm_bridge' has no member named 'of_node'
   remote = lvds->bridge->of_node;

We could work around that in the code, adding a Kconfig dependency
seems easier.

b24413180f License cleanup: add SPDX GPL-2.0 license identifier to files with no license
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.

adedbf0325 drm/rockchip: switch to drm_*_get(), drm_*_put() helpers
Use drm_*_get() and drm_*_put() helpers instead of drm_*_reference()
and drm_*_unreference() helpers.

drm_*_reference() and drm_*_unreference() functions are just
compatibility alias for drm_*_get() and drm_*_put() and should not be
used by new code. So convert all users of compatibility functions to
use the new APIs.

7d902c05b4 drm: Nuke drm_atomic_helper_connector_dpms
It's dead code, the core handles all this directly now.

The only special case is nouveau and tda988x which used one function
for both legacy modeset code and -nv50 atomic world instead of 2
vtables. But amounts to exactly the same.

v2: Rebase over the panel/brideg refactorings in stm/ltdc.

e6fc3b6855 drm: Plumb modifiers through plane init
This is the plumbing for supporting fb modifiers on planes. Modifiers
have already been introduced to some extent, but this series will extend
this to allow querying modifiers per plane. Based on this, the client to
enable optimal modifications for framebuffers.

This patch simply allows the DRM drivers to initialize their list of
supported modifiers upon initializing the plane.

v2: A minor addition from Daniel

v3:
* Updated commit message
* s/INVALID/DRM_FORMAT_MOD_INVALID (Liviu)
* Remove some excess newlines (Liviu)
* Update comment for > 64 modifiers (Liviu)

v4: Minor comment adjustments (Liviu)

v5: Some new platforms added due to rebase

v6: Add some missed plane inits (or maybe they're new - who knows at
this point) (Daniel)

The above IP version is from H/W define, some of vop support get
the IP version from VERSION_INFO register, some are not.
hardcode the IP version for each vop to identify them.

major version: used for IP structure, Vop full framework is 3,
               vop little framework is 2.
minor version: on same structure, newer design vop will bigger
               then old one.

All ctrl registers are using the sync write method that is

b9670ca20a drm/rockchip: fix Kconfig dependencies
A bug that I had fixed earlier just came back, with CONFIG_EXTCON=m,
the rockchip drm driver will fail to link:

drivers/gpu/drm/rockchip/cdn-dp-core.o: In function `cdn_dp_get_port_lanes':
cdn-dp-core.c:(.text.cdn_dp_get_port_lanes+0x30): undefined reference to `extcon_get_state'
cdn-dp-core.c:(.text.cdn_dp_get_port_lanes+0x6c): undefined reference to `extcon_get_property'
drivers/gpu/drm/rockchip/cdn-dp-core.o: In function `cdn_dp_check_sink_connection':
cdn-dp-core.c:(.text.cdn_dp_check_sink_connection+0x80): undefined reference to `extcon_get_state'
drivers/gpu/drm/rockchip/cdn-dp-core.o: In function `cdn_dp_enable':
cdn-dp-core.c:(.text.cdn_dp_enable+0x748): undefined reference to `extcon_get_property'

The problem is that that the sub-drivers are now all linked into the
main rockchip drm module, which breaks all the Kconfig dependencies
that are specified in the options for those sub-drivers.

This clarifies the dependency to ensure that we can only turn on the DP
driver when EXTCON is reachable. As the 'select' statements can now
cause additional options to become built-in when they should be
loadable modules, I'm moving those into the main driver config option.
The dependency on DRM_ROCKCHIP can be reduced into a single 'if'
statement here for brevity, but this has no functional effect.

Fixes: b6705157b2 ("drm/rockchip: add extcon dependency for DP")
Fixes: 8820b68bd3 ("drm/rockchip: Refactor the component match logic.")

0c1f528cb1 drm: handle HDMI 2.0 VICs in AVI info-frames
HDMI 1.4b support the CEA video modes as per range of CEA-861-D (VIC 1-64).
For any other mode, the VIC filed in AVI infoframes should be 0.
HDMI 2.0 sinks, support video modes range as per CEA-861-F spec, which is
extended to (VIC 1-107).

This patch adds a bool input variable, which indicates if the connected
sink is a HDMI 2.0 sink or not. This will make sure that we don't pass a
HDMI 2.0 VIC to a HDMI 1.4 sink.

This patch touches all drm drivers, who are callers of this function
drm_hdmi_avi_infoframe_from_display_mode but to make sure there is
no change in current behavior, is_hdmi2 is kept as false.

In case of I915 driver, this patch:
- checks if the connected display is HDMI 2.0.
- HDMI infoframes carry one of this two type of information:
	- VIC for 4K modes for HDMI 1.4 sinks
	- S3D information for S3D modes
  As CEA-861-F has already defined VICs for 4K videomodes, this
  patch doesn't allow sending HDMI infoframes for HDMI 2.0 sinks,
  until the mode is 3D.

Now that we have a callback to check if bridge supports a given mode
we can use it in Synopsys Designware HDMI bridge so that we restrict
the number of probbed modes to the ones we can actually display.

Also, there is no need to use mode_fixup() callback as mode_valid()
will handle the mode validation.

NOTE: I also had to change the pdata declaration of mode_valid
custom callback so that the passed modes are const. I also changed
in the platforms I found. Not even compiled it though.

efd11cc8fa drm/rockchip: Correct vop out_mode configure
Force vop output mode on encoder driver seem not a good idea,

EDP, HDMI, DisplayPort all have 10bit input on rk3399,
On non-10bit vop, vop 8bit output bit[0-7] connect to the
encoder high 8bit [2-9].

So force RGB10 to RGB888 on vop driver would be better.

And another problem, EDP check crtc id on atomic_check,
but encoder maybe NULL, so out_mode configure would fail,
it cause edp no display.

b0a45fec59 drm/rockchip: dw-mipi-dsi: improve PLL configuration
The multiplication ratio for the PLL is required to be even due to the
use of a "by 2 pre-scaler".  Currently we are likely to end up with an
odd multiplier even though there is an equivalent set of parameters with
an even multiplier.

For example, using the 324MHz bit rate with a reference clock of 24MHz
we end up with M = 27, N = 2 whereas the example in the PHY databook
gives M = 54, N = 4 for this bit rate and reference clock.

By walking down through the available multiplier instead of up we are
more likely to hit an even multiplier.  With the above example we do now
get M = 54, N = 4 as given by the databook.

While doing this, change the loop limits to encode the actual limits on
the divisor, which are:

	40MHz >= (pllref / N) >= 5MHz

These values are specified as constant time periods but the PHY

Panel drivers may want to sent commands during the disable function, for
example MIPI_DCS_SET_DISPLAY_OFF before the video signal ends.  In order
to send commands we need to write to registers, so pclk must be enabled.

While changing this, remove the unnecessary code after the panel
unprepare call which seems to be a workaround for a specific panel and
thus belongs in the panel driver.

The API is not suitable for subsystems consisting of multiple devices

implements allocation and address space management locally by using
helpers provided by DRM framework, like other DRM drivers do, e.g.

This patch should not introduce any functional changes until the driver
is made to attach subdevices into an IOMMU domain with the generic IOMMU
API, which will happen in following patch. Based heavily on GEM

81632df697 drm/rockchip: cdn-dp: do not use drm_helper_hpd_irq_event
The cdn_dp_pd_event_work is using drm_helper_hpd_irq_event to update the
connector status, this function is used to update all connectors of
drm_device. Therefore, the detect of other connector will be call, when
cdn_dp_pd_event_work is triggered, every time. It is not necessary, and
it may cause system crash. replace drm_helper_hpd_irq_event with
drm_kms_helper_hotplug_event, only update cdn-dp status.

5eb2e6ee97 drm/rockchip: cdn-dp: Do not run worker while suspended
If the driver is in suspended mode, the dp block may be disabled, and
chip registers may not be accessible. Yet, the worker may be triggered
in this situation by an extcon event. If that happens, the following crash
will be seen.

cdn-dp fec00000.dp: [drm:cdn_dp_pd_event_work] *ERROR* Enable dp failed -19

Problem is two-fold: The worker should not run while suspended, and the
suspend function should not call cdn_dp_disable() while the worker is
running.

83c132ed46 drm/rockchip: cdn-dp: Load firmware if no monitor connected
If no monitor is connected, suspend/resume cycles result in firmware
load errors because the driver attempts to load the firmware while
the system is in suspend state. This results in a kernel warning and
traceback.

Loading the firmware during boot fixes the problem. Note that we can not
just call schedule_work conditionally in cdn_dp_pd_event() if the insertion
status changed. The problem would still be seen if a monitor is connected
for the first time during suspend.

1a0f7ed3ab drm/rockchip: cdn-dp: add cdn DP support for rk3399
Add support for cdn DP controller which is embedded in the rk3399
SoCs. The DP is compliant with DisplayPort Specification,
Version 1.3, This IP is compatible with the rockchip type-c PHY IP.
There is a uCPU in DP controller, it need a firmware to work,
please put the firmware file to /lib/firmware/rockchip/dptx.bin. The
uCPU in charge of aux communication and link training, the host use
mailbox to communicate with the ucpu.
The dclk pin_pol of vop must not be invert for DP.

5a2c920c99 drm/rockchip: return ERR_PTR instead of NULL
rockchip_drm_framebuffer_init is only used in one case, in
rockchip_drm_fbdev.c, where its return value is tested using IS_ERR.  To
enable propagating the reason for the error, change the definition so that
it returns an ERR_PTR value.

Problem found with the help of Coccinelle.
