Gen2 tiles are 2KiB in size so i915_gem_object_get_tile_row_size()
can in fact return <4KiB, which leads to div-by-zero here.
Avoid that.
Not sure i915_gem_object_get_tile_row_size() is entirely
sane anyway since it doesn't account for the different tile
layouts on i8xx/i915.

So far we've sort of protected the global state under dev_priv with
the connection_mutex. I wan to change that so that we can change the
cdclk even for pure plane updates. To that end let's formalize the
protection of the global state to follow what I started with the cdclk

From: Ville Syrjälä
While not all platforms allow us to change the cdclk frequency
we should still verify that the fixed cdclk frequency isn't
too low. To that end let's cook up a .modeset_calc_cdclk()
implementation that only does the min_cdclk vs. actual cdclk
frequency check for such platforms
From: Ville Syrjälä
We need to insert stuff between the plane and crtc .atomic_check()
drm_atomic_helper_check_planes() doesn't allow us to do that so
stop using it and hand roll the loops instead.

Various pixel formats and plane scaling impose additional constraints
on the cdclk frequency. Provide a new plane->min_cdclk() hook that
will be used to compute the minimum acceptable cdclk frequency for
each plane.
Annoyingly on some platforms the numer of active planes affe
From: Ville Syrjälä
The normal cdclk handling now takes care of making sure the
plane's pixel rate doesn't exceed the spec appointed percentage
of the cdclk frequency. Thus we can nuke
skl_check_pipe_max_pixel_rate().

check_digital_port_conflicts() is done needlessly late. Move it earlier.
This will be needed as later on we want to set any_ms=true a bit later
for non-modesets too and we can't call this guy without the
connection_mutex held.

To make the logs a bit less confusing let's toss in some
debug prints to indicate whether the cdclk reprogramming
is going to happen with a single pipe active or whether we
need to turn all pipes off for the duration.

Now that the planes declare their minimum cdclk requirements properly
we don't need to check the cdclk in skl_max_scale() anymore. Just check
against the maximum downscale ratio, and move the code next to it's
only caller.

skl+ supports fp16 pixel formats on all universal planes. Add the
necessary bits to expose that capability. The main different to
icl is that we can't scale fp16, so need to add the relevant
checks.

gen4+ supports fp16 pixel formats on the primary planes. Add the
relevant code.
On ivb fp16 scanout is slightly busted. The output from the plane will
have 1/4 the expected value. For the primary plane we would have to
use the pipe gamma or pipe csc to correct that which woul

Resurrecting my possible_clones/crtcs cleanup from ~1 year ago.
Some prep work from the previous posting did get merged in the
meantime.
I have a feeling the WARNs from the new validation code may end up
triggering on some drivers, but I don't imagine this stuff would
get fix
From: Ville Syrjälä
The docs say possible_clones should always include the encoder itself.
Since most drivers don't want to deal with the complexities of cloning
let's allow them to set possible_clones=0 and instead we'll fix that
up in the core.
We can't put this special case into drm_encoder_i
From: Ville Syrjälä
I doubt the DP+DP and SDVO+SDVO cloning works for this driver.
i915 at least doesn't do those. Truthfully there could be some very
specific circumstances where some of them would do doable, but
genereally it's too much pain to deal with so we've chose not to
bother. Let's use
