Sam Ravnborg 2bda34d7d9 drm/exynos: drop drmP.h usage 
Drop use of the deprecated drmP.h file.
Replace with forwards / externals as appropriate.

While touching the list of include files divide
them up in blocks and sort them.

v3:
- fix build errors in exynos_drm_g2d.c (Inki Dae)
  The exynos_drm_g2d.c file is not built in the
  standard configurations and was therefore missed.

Daniel Vetter fcd70cd36b drm: Split out drm_probe_helper.h 
Having the probe helper stuff (which pretty much everyone needs) in
the drm_crtc_helper.h file (which atomic drivers should never need) is
confusing. Split them out.

To make sure I actually achieved the goal here I went through all
drivers. And indeed, all atomic drivers are now free of
drm_crtc_helper.h includes.

v2: Make it compile. There was so much compile fail on arm drivers
that I figured I'll better not include any of the acks on v1.

v3: Massive rebase because i915 has lost a lot of drmP.h includes, but
not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h
there was still one, which this patch largely removes. Which means
rolling out lots more includes all over.

This will also conflict with ongoing drmP.h cleanup by others I
expect.

v3: Rebase on top of atomic bochs.

v4: Review from Laurent for bridge/rcar/omap/shmob/core bits:
- (re)move some of the added includes, use the better include files in
  other places (all suggested from Laurent adopted unchanged).
- sort alphabetically

v5: Actually try to sort them, and while at it, sort all the ones I
touch.

v6: Rebase onto i915 changes.

v7: Rebase once more.

all drivers for the real Exynos DRM hardware modules. This ensures that
the resources will be released for the system PM suspend/resume cycle.

Kees Cook a86854d0c5 treewide: devm_kzalloc() -> devm_kcalloc() 
The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc().
This patch replaces cases of:

        devm_kzalloc(handle, a * b, gfp)

with:
        devm_kcalloc(handle, a * b, gfp)

as well as handling cases of:

        devm_kzalloc(handle, a * b * c, gfp)

with:

        devm_kzalloc(handle, array3_size(a, b, c), gfp)

as it's slightly less ugly than:

        devm_kcalloc(handle, array_size(a, b), c, gfp)

This does, however, attempt to ignore constant size factors like:

        devm_kzalloc(handle, 4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

Some manual whitespace fixes were needed in this patch, as Coccinelle
really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...".

The Coccinelle script used for this was:

Ville Syrjälä 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

Andrzej Hajda 36fd887acb drm/exynos/hdmi: quirk for support mode timings conversion 
MIXER in SoCs prior to Exynos5420 supports only 4 video modes:
720x480, 720x576, 1280x720, 1920x1080. Support for other modes
can be enabled by manipulating timings of HDMI. To do it
adjusted_mode should contain actual mode set on crtc.
With this patch it is possible to enable 1024x768 and 1280x1024
modes in MIXER.

Andrzej Hajda 991ea04e2c drm/exynos/hdmi: remove redundant mode field 
Display mode is preserved in CRTC state, there is no need to keep local
copy of it. Moreover since HDMI should configure registers according to
requested mode, use it instead of adjusted_mode, which should contain
mode produced by CRTC - functionally it does not change anything, but
subsequent patches will make the difference.

Arnd Bergmann 7e17510018 drm: exynos: mark pm functions as __maybe_unused 
The rework of the exynos DRM clock handling introduced
warnings for configurations that have CONFIG_PM disabled:

drivers/gpu/drm/exynos/exynos_hdmi.c:736:13: error: 'hdmi_clk_disable_gates' defined but not used [-Werror=unused-function]
 static void hdmi_clk_disable_gates(struct hdmi_context *hdata)

 static int hdmi_clk_enable_gates(struct hdmi_context *hdata)

The problem is that the PM functions themselves are inside of
an #ifdef, but some functions they call are not.

This patch removes the #ifdef and instead marks the PM functions
as __maybe_unused, which is a more reliable way to get it right.

Shashank Sharma 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.

Andrzej Hajda 625e63e27c drm/exynos/hdmi: fix pipeline disable order 
Hardware require that MIXER(crtc) should be disabled prior to
HDMI(encoder). It was achieved by disabling crtc from encoder disable
callback, bypassing drm core. As a result drm core tried to call vblank
related routines on disabled crtc. The patch fixes it by simplifying
hdmi_disable routine - now it only cancels hotplug worker. Hardware will
be disabled in proper moment during pipe clock disable.

   - added support for Intel SR300 Depth camera

   - some improvements at CEC and RC core

   - lots of driver cleanups, improvements all over the tree

  With this series, we're finally getting rid of the LIRC staging
  driver. There's just one left (lirc_zilog), with require more care,
  as part of its functionality (IR RX) is already provided by another
  driver. Work in progress to convert it on the proper way"

The vblank hooks in struct drm_driver are deprecated and only meant for
legacy drivers.  For modern drivers with DRIVER_MODESET flag, the hooks
in struct drm_crtc_funcs should be used instead.

As the result, exynos_drm_crtc_enable[disable]_vblank() become static
functions.  They are moved around a bit to save forward declaration
though.  Also while at it, we move one step further to kill
exynos_drm_crtc_from_pipe() completely by updating hdmi_bind() a bit.

so this code can be ignored.

Boris Brezillon 1487a81941 drm: exynos: Rely on the default ->best_encoder() behavior 
We have 1:1 relationship between connectors and encoders and the driver
is relying on the atomic helpers: we can drop the custom ->best_encoder()
implementations and let the core call drm_atomic_helper_best_encoder()
for us.

Javier Martinez Canillas b85881ddf2 drm/exynos/hdmi: Don't print error on deferral due to regulators 
The regulators may not be available just because their driver's probe
function was just not executed and so the regulators not registered.

So, in this case the Exynos HDMI driver should not print logs since
a -EPROBE_DEFER is not really an error and that will just pollute
the kernel log and confuse users.

This patch prevents the following misleading messages to be printed:

[    1.443638] [drm:hdmi_probe] *ERROR* failed to get regulators
[    1.449326] [drm:hdmi_probe] *ERROR* hdmi_resources_init failed
