96550555a7 drm/i915: Pass down rc in intel_encoder->compute_config()
Something that I completely missed when implementing the new MST VCPI
atomic helpers is that with those helpers, there's technically a chance
of us having to grab additional modeset locks in ->compute_config() and
furthermore, that means we have the potential to hit a normal modeset
deadlock. However, because ->compute_config() only returns a bool this
means we can't return -EDEADLK when we need to drop locks and try again
which means we end up just failing the atomic check permanently. Whoops.

So, fix this by modifying ->compute_config() to pass down an actual
error code instead of a bool so that the atomic check can be restarted
on modeset deadlocks.

Thanks to Ville Syrjälä for pointing this out!

Changes since v1:
* Add some newlines
* Return only -EINVAL from hsw_crt_compute_config()
* Propogate return code from intel_dp_compute_dsc_params()
* Change all of the intel_dp_compute_link_config*() variants
* Don't miss if (hdmi_port_clock_valid()) branch in
  intel_hdmi_compute_config()

ed20151a76 drm/vblank: Allow dynamic per-crtc max_vblank_count
On i965gm we need to adjust max_vblank_count dynamically
depending on whether the TV encoder is used or not. To
that end add a per-crtc max_vblank_count that takes
precedence over its device wide counterpart. The driver
can now call drm_crtc_set_max_vblank_count() to configure
the per-crtc value before calling drm_vblank_on().

Also looks like there was some discussion about exynos needing
similar treatment.

v2: Drop the extra max_vblank_count!=0 check for the
    WARN(last!=current), will take care of it in i915 code (Daniel)
    WARN_ON(!inmodeset) (Daniel)
    WARN_ON(dev->max_vblank_count)

8e93f1028d drm/mxsfb: Use drm_fbdev_generic_setup()
The CMA helper is already using the drm_fb_helper_generic_probe part of
the generic fbdev emulation. This patch makes full use of the generic
fbdev emulation by using its drm_client callbacks. This means that
drm_mode_config_funcs->output_poll_changed and drm_driver->lastclose are
now handled by the emulation code. Additionally fbdev unregister happens
automatically on drm_dev_unregister().

The drm_fbdev_generic_setup() call is put after drm_dev_register() in the
driver. This is done to highlight the fact that fbdev emulation is an
internal client that makes use of the driver, it is not part of the
driver as such. If fbdev setup fails, an error is printed, but the driver
succeeds probing.

9a47db8e7a drm: rcar-du: Remove inclusion of drmP.h
The DRM kernel API used to be defined in a handful of headers, pulled in
through drmP.h. It has since been split in multiple headers for the
different DRM components, and drmP.h turned into a legacy header that
just pulls in most of the DRM kernel API (and a large number of other
miscellaneous kernel headers).

In order to speed up compilation, replace inclusion of drmP.h with only
the required headers. It turns out that the rcar-du-drm driver already
includes most of the necessary headers, so the change is simple.

While at it, remove unneeded inclusion of other headers, and unneeded
forward declarations of structures.

dedd876c94 drm: rcar-du: Disable unused DPAD outputs
DU channels are routed to DPAD outputs in an SoC-dependent way. The
routing can be fixed (e.g. DU3 to DPAD0 on H3) or configurable (e.g. DU0
or DU1 to DPAD0 on D3/E3). The hardware offers no option to disconnect
DPAD outputs, which are thus always driven by a DU channel.

On SoCs that have less DU channels than DU outputs, such as D3 and E3,
the DPAD output is always driven when all channels are in use by other
outputs (such as the internal LVDS and HDMI encoders). This creates an
unwanted clone on the DPAD output.

However, the parallel output of the DU channels routed to DPAD can be
set to fixed levels in the DU channels themselves through the DOFLR
group register. Use this to turn the DPAD on or off by driving fixed
signals at the output of any DU channel not routed to a DPAD output.
This doesn't affect the DU output signals going to other outputs.

b8a43032a7 drm: rcar-du: Move CRTC outputs bitmask to private CRTC state
The rcar_du_crtc outputs field stores a bitmask of the outputs driven by
the CRTC. This changes based on the configuration requested by
userspace, and is used for the sole purpose of configuring the hardware.
The field thus belongs to the CRTC state. Move it to the
rcar_du_crtc_state structure.

As a result the rcar_du_crtc_route_output() function loses most of its
purpose. In order to remove it, move dpad0_source calculation to
rcar_du_atomic_commit_tail(), until the field gets moved to a state
structure. In order to simplify the rcar_du_group_set_routing()
implementation, we also store the DPAD1 source in a new dpad1_source
field which will move to a state structure with dpad0_source.

- Video layer 0 (Win0)
- Video layer 1 (Win1)
- OSD layer     (Win2)

Win0 and Win1 are exchangeable.
Maximum resolution is 1920x1080.

The LCDC0 output is connected to:
- LCDC0 IO (without IOMUX)
- HDMI TX video input

The LCDC1 output is connected to:
- LCDC1 IO (with IOMUX)
- HDMI TX video input

The HDMI TX input can switch between LCDC0 and LCDC1.

The TPO (Toppoly) TPG110 is a pretty generic display driver
similar in vein to the Ilitek 93xx devices. It is not a panel
per se but a driver used with several low-cost noname panels.

This is used on the Nomadik NHK15 combined with a OSD
OSD057VA01CT display for WVGA 800x480.

The driver is pretty minimalistic right now but can be
extended to handle non-default polarities, gamma correction
etc.

The driver is based on the baked-in code in
drivers/video/fbdev/amba-clcd-nomadik.c which will be
decomissioned once this us upstream.

drm: Auto-set allow_fb_modifiers when given modifiers at plane init
When drivers pass non-empty lists of modifiers for initializing their
planes, we can infer that they allow framebuffer modifiers and set the
driver's allow_fb_modifiers mode config element.

In case the allow_fb_modifiers element was not set (some drivers tend
to set them after registering planes), the modifiers will still be
registered but won't be available to userspace unless the flag is set
later. However in that case, the IN_FORMATS blob won't be created.

In order to avoid this case and generally reduce the trouble associated
with the flag, always set allow_fb_modifiers when a non-empty list of
format modifiers is passed at plane init.

Remove further checks that are no longer necessary along the way, since
semi-planar YUV420 formats support every SAND tiling mode.
