Now that we have infoframes to report the pixel repeat flag, we can
start using it. Fixes locking the 720x480i and 720x576i modes on my
Dell 2408WFP. Like the 1920x1080i case, they don't fit properly on
the screen, though.

Fixes a purple bar on the left side of the screen with my Dell
2408WFP. It will also be required for supporting the double-clocked
video modes.

We really do need to be using the halved V fields. I had been
confused by the code I was using as a reference because it stored
halved vsync fields but not halved vdisplay, so it looked like I only
needed to divide vdisplay by 2.
This reverts part of Mario's timestamping fixes that prevented
CRTC_HALVE_V from applying, and instead adjusts the timestamping code
to not use the crtc field in that case.
Fixes locking of 1920x1080x60i on my Dell 2408WFP. There are black
bars on the top and bottom, but I suspect that might be an
under/overscan flags problem as opposed to video timings.

Fixes occasional debug spew at boot when connected directly through
HDMI, and probably confusing the HDMI state machine when we go trying
to poke registers for the enable sequence too soon.

On Pi0/1/2, we use an external GPIO line for hotplug detection, since
the HDMI_HOTPLUG register isn't connected to anything. However, with
the Pi3 the HPD GPIO line has moved off to a GPIO expander that will
be tricky to get to (the firmware is constantly polling the expander
using i2c0, so we'll need to coordinate with it).
As a stop-gap, if we don't have a GPIO line, use an EDID probe to
detect connection. Fixes HDMI display on the pi3.

Fixes broken grayscale ramps on many HDMI monitors, where large areas
at the ends of the ramp would all appear as black or white.

We must not apply CRTC_INTERLACE_HALVE_V to interlaced modes during
mode enumeration, as drm_helper_probe_single_connector_modes
does, so wrap it and reset the effect of CRTC_INTERLACE_HALVE_V
on affected interlaced modes.
Also mode_fixup interlaced modes passed in from user space.
This fixes the vblank timestamping constants and entries in
the mode->crtc_xxx fields needed for precise vblank timestamping.

drm-next
This pull request brings in new vc4 plane formats for Android, precise
vblank timestamping, and a couple of small cleanups.
* tag 'drm-vc4-next-2016-07-12' of https://github.com/anholt/linux:
drm/vc4: remove redundant ret status check
drm/vc4: Implement precise vblank timestamping.
drm/vc4: Bind the HVS before we bind the individual CRTCs.

of_node_put needs to be called when the device node which is got
from of_parse_phandle has finished using.

All outputs have a 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.

If you make it here other than through err_destroy_encoder, vc4->hdmi
is still NULL.

The original Raspberry Pi had the GPIO active high, but the later
models are active low. The DT GPIO bindings allow specifying the
active flag, except that it doesn't get propagated to the gpiodesc, so
you have to handle it yourself.

If the firmware hadn't brought up HDMI for us, we need to do its
power-on reset sequence (reset HD and and clear its STANDBY bits,
reset HDMI, and leave the PHY disabled).

Done with coccinelle for the most part. However, it thinks '...' is
part of the semantic patch, so I put an 'int DOTDOTDOT' placeholder
in its place and got rid of it with sed afterwards.

This is enough for fbcon and bringing up X using
xf86-video-modesetting. It doesn't support the 3D accelerator or
power management yet.
v2: Drop FB_HELPER select thanks to Archit's patches. Do manual init
ordering instead of using the .load hook. Structure registration
more like tegra's, but still using the typical "component" code.
Drop no-op hooks for atomic_begin and mode_fixup() now that
they're optional. Drop sentinel in Makefile. Fix minor style
nits I noticed on another reread.
v3: Use the new bcm2835 clk driver to manage pixel/HSM clocks instead
of having a fixed video mode. Use exynos-style component driver
matching instead of devicetree nodes to list the component driver
instances. Rename compatibility strings to say bcm2835, and
distinguish pv0/1/2. Clean up some h/vsync code, and add in
interlaced mode setup. Fix up probe/bind error paths. Use
bitops.h macros for vc4_regs.h
v4: Include i2c.h, allow building under COMPILE_TEST, drop msleep now
that other bugs have been fixed, add timeouts to cpu_relax()
loops, rename hpd-gpio to hpd-gpios.
