It appears that, for whatever reason, both link A and B use the same
register to control the training pattern. It's a little odd, as the
GPUs before this (Tesla/Fermi1) have per-link registers, as do newer
GPUs (Maxwell).
Fixes the third DP output on NVS 510 (GK107).

There is redundant code in the clean up exit path when dpi_connector
fails to be allocated. The current code checks if connector is NULL
before destroying it, in fact, connector is NULL at this point so
the check is redundant and can be removed. The final clean up is
that we can remove the goto fail with a simple return and the unused
variable ret.

Protect both the setup of the pageflip event and the
latching of the new requested displaylist head pointer
by the event lock, so we can't get into a situation
where vc4_atomic_flush latches the new display list via
HVS_WRITE, then immediately gets preempted before queueing
the pageflip event, then the page-flip completes in hw and
the vc4_crtc_handle_page_flip() runs and no-ops due to
lack of a pending pageflip event, then vc4_atomic_flush
continues and only then queues the pageflip event - after
the page flip handling already no-oped. This would cause
flip completion handling only at the next vblank - one
frame too late.
In vc4_crtc_handle_page_flip() check the actual DL head
pointer in SCALER_DISPLACTX against the requested pointer
for page flip to make sure that the flip actually really
completed in the current vblank and doesn't get deferred
to the next one because the DL head pointer was written
a bit too late into SCALER_DISPLISTX, after start of
vblank, and missed the boat. This avoids handling a
pageflip completion too early - one frame too early.
According to Eric, DL head pointer updates which were
written into the HVS DISPLISTX reg get committed to hardware
at the last pixel of active scanout. Our vblank interrupt
handler, as triggered by PV_INT_VFP_START irq, gets to run
earliest at the first pixel of HBLANK at the end of the
last scanline of active scanout, ie. vblank irq handling
runs at least 1 pixel duration after a potential pageflip
completion happened in hardware.
This ordering of events in the hardware, together with the
lock protection and SCALER_DISPLACTX sampling of this patch,
guarantees that pageflip completion handling only runs at
exactly the vblank irq of actual pageflip completion in all
cases.
Background info from Eric about the relative timing of
HVS, PV's and trigger points for interrupts, DL updates:
https://lists.freedesktop.org/archives/dri-devel/2016-May/107510.html
Tested on RPi 2B with hardware timing measurement equipment
and shown to no longer complete flips too early or too late.

Contrary to other flags to DRM_IOCTL_DEF_DRV(), which restrict usage,
the flag for render node is an enabler (the IOCTL can't be used from
render node if it's not present). So DRM_RENDER_ALLOW needs to be

At the moment we calculate the buffer's pitch with:
pitch = width * DIV_ROUND_UP(bpp, 8)
For CLUT modes with bpp of 1/2/4/8 this gives wrong result, and the
correct pitch is:
pitch = DIV_ROUND_UP(width * bpp, 8)
In practice this doesn't change anything, as we don't support CLUT
modes, but it's better to have the pitch calculation correct.

The previous commit removed aligning the pitch to SGX's pitch
requirement from align_pitch(). What's left is effectively a function
that returns width * bytespp.
To clean up the driver, we can remove the function and have the
calculation inline in the two places which call align_pitch().

omapdrm checks if the pixel stride is divisible by 8. This is meant to
ensure that the byte stride is 32, which is required by SGX.
The check is not correct, as it checks for pixels, not bytes, and thus
needlessly increases the stride for, e.g., NV12.
Also, SGX driver is not supported in the mainline, and the TI's SGX
driver nowadays does the memory allocation itself and doesn't rely on
omapdrm to figure out the correct pitch.
So we can just remove the whole roundup.

Fix the failure mode where the display appears split, or shifted about
2/3 of the screen, and the color components are cycled. Turns out we
were missing the crucial BXT_DEFEATURE_DPI_FIFO_CTR bit in the
EOT_DISABLE register.
Per bspec, with the bit set, the "mipi_dpf_vblank_start" signal is
asserted only when the complete frame is transferred in the DPHY line
and also the DPI FIFO is flushed out at the end of each frame.
The problem was mitigated by keeping the panel fitter enabled, but that
only limited the issue to a shift of about 0..10 pixels. With the fix
here, the panel fitter workaround does not seem to be needed at all.
While at it, set BXT_DPHY_DEFEATURE_EN in EOT_DISABLE register which is
also needed per the BXT DSI mode set sequence.
