Use the actual tile size as to compute stuff in
intel_fill_fb_ggtt_view() instead of assuming it's PAGE_SIZE. I suppose
it doesn't matter since we don't use the results on gen2 platforms
where the tile size is 2k.

I find more usual to think about tile widths than heights, so changing
the intel_tile_height() to calculate the tile height as
tile_size/tile_width is easier than the opposite to the poor brain.

drm/i915: Introduce a gmbus power domain
gmbus also needs the power domain infrastructure right from the start,
since as soon as we register the i2c controllers someone can use them.
v2: Adjust cleanup paths too (Chris).
v3: Rebase onto -nightly (totally bogus tree I had lying around) and
also move dpio init head (Ville).
v4: Ville instead suggested to move gmbus setup later in the sequence,
since it's only needed by the modeset code.
v5: Move even close to the actual user, right next to the comment that
states where we really need gmbus (and interrupts!).

An encoder is associated with a connector by the DRM core as a result of
setting up a configuration. Drivers using the atomic or legacy helpers
should never set up this link, even if it is a static one.
While at it, try to catch this kind of error in the future by adding a
WARN_ON() in drm_mode_connector_attach_encoder(). Note that this doesn't
cover all the cases, since drivers could set this up after attaching.
Drivers that use the atomic helpers will get a warning later on, though,
so hopefully the two combined cover enough to help people avoid this in
the future.

This fixes reprobing of display connectors on resume. After some
talking with danvet on IRC, I learned that calling
drm_helper_hpd_irq_event() does actually trigger a full reprobe of each
connector's status. It turns out this is the actual reason reprobing on
resume hasn't been working (this was observed on a T440s):
- We call hpd_init()
- We check each connector for a couple of things before marking
connector->polled with DRM_CONNECTOR_POLL_HPD, one of which is an
active encoder. Of course, a disconnected port won't have an
active encoder, so we don't add the flag to any of the
connectors.
- We call drm_helper_hpd_irq_event()
- drm_helper_irq_event() checks each connector for the
DRM_CONNECTOR_POLL_HPD flag. The only one that has it is eDP-1,
so we skip reprobing each connector except that one.
In addition, we also now avoid setting connector->polled to
DRM_CONNECTOR_POLL_HPD for MST connectors, since their reprobing is
handled by the mst helpers. This is probably what was originally
intended to happen here.
Changes since V1:
* Use the explanation of the issue as the commit message instead
* Change the title of the commit, since this does more then just stop a
check for an encoder now
* Add "Fixes" line for the patch that introduced this regression
* Don't enable DRM_CONNECTOR_POLL_HPD for mst connectors
Changes since V2:
* Put patch changelog above Signed-off-by
* Follow Daniel Vetter's suggestion for making the code here a bit more
legible

Following a GPU reset, we may leave the context in a poorly defined

secondary contexts, this will lead to that context being banned - but
currently it is also causing the default context to become banned,
leading to turmoil in the shared state.

This patch fixes a kernel panic issue which happened
when drm driver is closed while modetest.
This issue could be reproduced easily by launching modetest
with page flip repeatedly.
The reason is that invalid drm_file object could be accessed by
send_vblank_event function when finishing page flip if the drm_file
object was removed by drm_release and there was a pended page
flip event which was already committed to hardware.
So this patch makes the pended page flip event to be cancelled by
preclose callback which is called at front of drm_release function.
Changelog v2:
- free vblank event objects belonging to the request process,
increment event space and decrease pending_update when cancelling
the event

'zpos' plane property is configurable, so adjust hardware layers
priority based on the zpos value. 'zpos' value shifted by one can be
used directly as hw priority value and stored to the registers, because
mixer accepts priority values from 1 to 15 (0 means that layer is
disabled).
This patch also changes the default layer priority to match already
exposed initial zpos values. The initial configuration is now:
[top] video > gfx layer1 > gfx layer0 [bottom].

MI_BATCH_BUFFER is nasty since it requires that userspace pass in the
correct batch length.
Let's switch to using MI_BATCH_BUFFER_START instead (like we do on
other platforms). Then we don't have to specify the batch length
at all, and the CS will instead execute until it sees the
MI_BATCH_BUFFER_END.
We still need the batch length since we do the CS TLB workaround
and copy the batch into the permanently pinned scratch object
and execute it from there. But for this we can simply use the
batch object length when the user hasn't specified the actual
batch length. So specifying the batch length becomes just a
way to optimize the batch copy a little bit.
We lost batch_len from a bunch of igts (including the quiesce batch)
so without this igt is utterly broken on 830/845. Also some igts such
as gem_cpu_reloc never specified the batch_len and so didn't work.
With MI_BATCH_BUFFER_START we don't have to fix up igt every time
someone forgets that 830/845 exist.

My 85x has VBT version 108 which has a child dev size of 27 bytes.
Let's allow that without printing an error.
We still want to reject the actual parsin since for that we need
the child device size to be at least 33 bytes. So we should still
check for that, but let's make it print a debug message only instead
of an error.
While at it, toss in a BUILD_BUG_ON() to verify our struct
old_child_dev_config is in fact 33 bytes.

We use the vblank timestamps to generate the vblank frame counter value
on gen2. That means we need the pipe scanout position to be accurate
when we call drm_crtc_vblank_on(), otherwise the frame counter
guesstimate may jump when the pipe actually start.
What I observed on my 85x is that the DSL initially reads 0, and when
the pipe actually starts DSL jumps to vblank_start. On gen2 DSL==0 means
actually vtotal-1 (see update_scanline_offset()), so if we initially
get vtotal-1, and then very quickly vblank_start (or thereabouts), the
scanout position will appear to jump backwards by approximately one
vblank length. Which means the frame counter guesstimate will also
jump backwards. That's no good, so let's make sure the pipe has
started before we call drm_crtc_vblank_on().

We're supposed to pass the primary DP encoder to intel_ddi_clk_select(),
not the fake MST encoder. Do so.
There's no real bug here though, since intel_ddi_clk_select() only
checks if the encoder type is EDP (which it isn't for either the
primary DP encoder or the fake MST encoder), and it gets the DDI port
via intel_ddi_get_encoder_port() (which knows how to do the
fake->primary->port dance itself).
