The %* format specifier expects an integer, which works fine with size_t
arguments on 32-bit because the types match. However on 64-bit, size_t
is typedef'd to unsigned long and will cause a build warning.

There are several different models of N116BGE. According to commit
0a2288c06aab ("drm/panel: simple: Add Innolux N116BGE panel support"),
the video timings are for the eDP variant.
The clock and htotal values added by that patch are out of spec
according to the datasheets I have seen for the eDP N116BGE (-EA2 and
-EB2).
This patch changes the values to the "Typ" values on the datasheet.

The Hitachi TX23D38VM0CAA is a 9" WVGA TFT LCD panel and can be
supported by the simple-panel driver.
This panel is connected via LVDS and uses the data enable signal for
timing. Since HSYNC/VSYNC are ignored, the split between sync length and
porches is arbitrary, as long as the complete horizontal blanking interval
is 256 clocks, and the vertical blanking interval is 45 lines.

Various panels were missing the .bpc field which encodes the number of
bits per color. Not every display driver relies on this value, but since
the panels can be used with any display engine it must be specified so
that if a driver knows how to differentiate based on this field it can
do so.

Currently both forms (with or without the flags argument) are valid

will be removed once all consumers are updated and the flags argument
will become compulsary.

We need the HPLL frequency when calculating cdclk. Currently we read
that out from the hardware every single time, which isn't going to fly
very well if the device is runtime suspended. So cache the HPLL
frequency in dev_priv and use the cached value.

This simplifies the code quite a bit compared to iterating over all
rings during the ring interrupt.
Also, it allows us to drop the mmio_flip spinlock, since the mmio_flip
struct is only accessed in two places. The first is when the flip is
queued and the other when the mmio writes are done. Since a flip cannot
be queued while there is a pending flip, the two paths shouldn't ever
run in parallel. We might need to revisit that if support for replacing
flips is implemented though.

modeset_update_crtc_power_domains()
We may need to access various hardware bits in the .global_resources()
hook, so move the call to occur after enabling all the newly required
power wells, but before disabling all the now unneeded wells. This
should guarantee that we have all the sufficient hardware resources
available during the .global_resources() call. And if not, any additional
resources must be explicitly acquired by the .global_resorces() hook.
For instance on VLV/CHV we need to access the gunit mailbox so that we
can talk to punit/cck over sideband. In addition some PFI credit
reprogramming may need to be addes as well, which may require the disp2d
well.
This should also make the power domain refcounts consistent on platforms
which don't have a .global_resource() hook since now they too will
call modeset_update_crtc_power_domains() which will drop the init power.
Previously init power was just left enabled for such platforms.

When we write new values for the DDB allocation and WM parameters, we now
need to trigger the double buffer update for the pipe to take the new
configuration into account.
As the DDB is a global resource shared between planes, enabling or
disabling one plane will result in changes for all planes that are
currently in use, thus the need write PLANE_SURF/CUR_BASE for more than
the plane we're touching.
v2: Don't wait for pipes that are off
v3: Split the staging results structure to not exceed the 1Kb stack
allocation in skl_update_wm()
v4: Rework and document the algorithm after Ville found that it was all
wrong.

To correctly flush the new DDB allocation we need to know about the pipe
allocation layout inside the DDB in order to sequence the re-allocation
to not cause a newly allocated pipe to fetch from a space that was
previously allocated to another pipe.
This patch preserves the per-pipe (start,end) allocation to be used in
the flush.

The transition WMs code was doing a shortcut and the values were copied
from the WM0 ones at compute_wm_results() time. Going forward, we want
to compute them like the other WMs and resolve their final register
values in the same way as well.
This patch does just that and isolate the transtion WM compute code in
skl_compute_transition_wm() while skl_compute_wm_results() takes care of
the register values.
We also take the opportunity to disable the transition WMs for now.
We've noticed underruns and they seem to be the culprit.

To align with the ilk WM code and because it makes sense to test against
the upper bounds as soon as possible on variables that are bigger than
the number of bits in the register, let's move the maximum checks from
skl_compute_wm_results() to skl_compute_plane_wm().
v2: Leave the result values to 0 when overflowing the limits (Ville)
Use 32 bits intermediate variables (Damien)
Instead of using the 16 and 8 bits space we have in the result
structure, use 32 bits local variables until we're sure they fit into
the constraints.
