commit 6dffd431e229 ("drm: Add aspect ratio parsing in DRM layer")
cause us to not send out any VICs in the AVI infoframes. That commit
was since reverted, but if and when we add aspect ratio handing back
we need to be more careful.
Let's handle this by considering the aspect ratio as a requirement
for cea mode matching only if the passed in mode actually has a
non-zero aspect ratio field. This will keep userspace that doesn't
provide an aspect ratio working as before by matching it to the
first otherwise equal cea mode. And once userspace starts to
provide the aspect ratio it will be considerd a hard requirement
for the match.
Also change the hdmi mode matching to use drm_mode_match() for
consistency, but we don't match on aspect ratio there since the
spec doesn't list a specific aspect ratio for those modes.

Use drm_mode_equal_no_clocks_no_stereo() in
drm_match_hdmi_mode_clock_tolerance() for consistency as we
also use it in drm_match_hdmi_mode() and the cea mode matching
functions.
This doesn't actually change anything since the input mode
comes from detailed timings and we match it against
edid_4k_modes[] which. So none of those modes can have stereo
flags set.

DP_TRAINING_AUX_RD_INTERVAL with DP 1.3 spec changed bit scheeme from 8
bits to 7 in DPCD 0x000e. The 8th bit is used to identify extended
receiver capabilities. For panels that use this new feature wait interval
would be increased by 512 ms, when spec is max 16 ms. This behavior is
described in table 2-158 of DP 1.4 spec address 0000eh.
With the introduction of DP 1.4 spec main link clock recovery was
standardized to 100 us regardless of TRAINING_AUX_RD_INTERVAL value.
To avoid breaking panels that are not spec compiant we now warn on

With the previous patch drm_atomic_helper_check_plane_state correctly
calculates clipping and the xf86-video-intel ddx is fixed to fall back
to GPU correctly when SetPlane fails, we can remove the hack where
we try to pan/zoom when out of min/max scaling range. This was already
poor behavior where the screen didn't show what was requested, and now
instead we reject it outright. This simplifies check_sprite_plane a lot.
Changes since v1:
- Set crtc_h to the height correctly.
- Reject < 3x3 rectangles instead of making them invisible for <gen9.
For gen9+ skl_update_scaler_plane will reject them.

Instead of relying on a scale which may increase rounding errors,
clip src by doing: src * (dst - clip) / dst and rounding the result
away from 1, so the new coordinates get closer to 1. We won't need
to fix up with a magic macro afterwards, because our scaling factor
will never go to the other side of 1.
Changes since v1:
- Adjust dst immediately, else drm_rect_width/height on dst gives bogus
results.
Change since v2:
- Get rid of macros and use 64-bits math.

I had originally asked Stefan Schake to drop the pad field from the
syncobj changes that just landed, because I couldn't come up with a
reason to align to 64 bits.
Talking with Dave Airlie about the new v3d driver's submit ioctl, we
came up with a reason: sizeof() on 64-bit platforms may align to 64
bits, in which case the userspace will be submitting the aligned size
and the final 32 bits won't be zero-padded by the kernel. If
userspace doesn't zero-fill, then a future ABI change adding a 32-bit
field at the end could potentially cause the kernel to read undefined
data from old userspace (our userspace happens to use structure
initialization that zero-fills, but as a general rule we try not to
rely on that in the kernel).

dma-buf/fence: add fence_wait_any_timeout function v2
there was a restriction added that this only works if the dma-fence
uses the dma_fence_default_wait hook. Which works for amdgpu, which is
the only caller. Well, until you share some buffers with e.g. i915,
then you get an -EINVAL.
But there's really no reason for this, because all drivers must
support callbacks. The special ->wait hook is only as an optimization;
if the driver needs to create a worker thread for an active callback,
then it can avoid to do that if it knows that there's a process
context available already. So ->wait is just an optimization, just
using the logic in dma_fence_default_wait() should work for all
drivers.
Let's remove this restriction.

The Versatile Express uses a special configuration controller
deeply embedded in the system motherboard FPGA to multiplex the
two to three (!) display controller instances out to the single
SiI9022 bridge.
Set up an extra file with the logic to probe to the FPGA mux
register on the system controller bus, then parse the device
tree to see if there is a CLCD or HDLCD instance on the core
tile (also known as the daughterboard) by looking in the
root of the device tree for compatible nodes.
- If there is a HDLCD on the core tile, and there is a driver
for it, we exit probe and deactivate the motherboard CLCD.
We do not touch the DVI mux in this case, to make sure we
don't break HDLCD.
- If there is a CLCD on both the motherboard and the core tile
(only the CA9 has this) the core tile CLCD takes precedence
and get muxed to the DVI connector.
- Only if there is no working graphics on the core tile, the
motherboard CLCD is probed and muxed to the DVI connector.
Core tile graphics should always take precedence as it can
address all memory and is also faster, however the motherboard
CLCD is good to have around for diagnostics and testing.
It is possible to test the motherboard CLCD by setting the
status = "disabled" property on the core tile CLCD or
HDLCD.
Scale down the Versatile Express to 16BPP so we can support a
1024x768 display despite the bus bandwidth restrictions on this
platform. (The motherboard CLCD supports slightly lower
resolution.)

It turns out that I had just mistaken what type of write the register
writes were supposed to be, using DCS instead of generic long writes.
Switching to transactions instead of using the atmel as a bridge also
seems to resolve the sparkling pixels problem I've had.

The PiTFT (ili9340) has a hardware reset circuit that resets only
on power-on and not on each reboot through a gpio like the
rpi-display does. As a result, we need to always apply the
rotation value regardless of the display "on/off" state.
Moved the rotation setting code below out_enable:.
