Add a new subdirectory for display code, and start off by moving
modesetting output/encoder code. Judging by the include changes, this is
a surprisingly clean operation.
v2:
- move intel_sdvo_regs.h too
- use tabs for Makefile file lists and sort them

The GOP sometimes initializes the pclk at a (slightly) different frequency
then the pclk which we've calculated.
This commit makes the DSI code read-back the pclk set by the GOP and
if that is within a reasonable margin of the calculated pclk, uses
that instead.
This fixes the first modeset being a full modeset instead of a
fast modeset on systems where the GOP pclk is different.
Changes in v2:
-Use intel_encoder_current_mode() to get the pclk setup by the GOP
Changes in v3:
-Back to the readback approach, skipping the dsi_pll.ctrl / .dev checks
in intel_pipe_config_compare() when adjust is set leads to:
[drm:pipe_config_err [i915]] *ERROR* mismatch in dsi_pll.ctrl (...)
[drm:pipe_config_err [i915]] *ERROR* mismatch in dsi_pll.div (...)
-Do the readback and pclk overriding from vlv_dsi_init(), rather then from
intel_dsi_vbt_init() as the vbt code should not be touching the hw

The vlv/icl_dphy_param_init calls do various calculations to set dphy
parameters based on the pclk.
Move the calling of vlv/icl_dphy_param_init to vlv_dsi_init to give
vlv_dsi_init a chance to tweak the pclk before these calculations are done.
Changes in v2:
-Also moves the icl and vlv specific dphy_param_init functions from the
generic intel_dsi_vbt.c file into the icl_ and vlv_dsi.c specific files.
Note icl_dphy_param_init() and vlv_dphy_param_init() are only moved,
otherwise they are completely unchanged.

As we now employ a very heavy pm_qos around the punit access, we want to
minimise the number of synchronous requests by performing one for the
whole punit sequence rather than around individual accesses. The
sideband lock is used for this, so push the pm_qos into the sideband
lock acquisition and release, moving it from the lowlevel punit rw
routine to the callers. In the first step, we move the punit magic into
the common sideband lock so that we can acquire a bunch of ports
simultaneously, and if need be extend the workaround protection later.

The only bpc information in pipe registers for BXT/GLK DSI
is the PIPEMISC dither bpc. Let's try to use that to read
out pipe_bpp on these platforms. However, I'm not sure if
this will be correctly populated by the GOP since bspec
suggests it's only needed if dithering is actually enabled.
If not I guess we'll have to go one step further and
extract pipe_bpp from the DSI pixel format when dithering
is disabled.

First of all GMCH can be considered a feature by itself
since it is a chip present in some platforms that connects
the IA processor to memory and other components in PC.
Also with the introduction of display block at device info,
we got a redundant definition:
.display.has_gmch_display = 1,
So, let's clean up things a bit and use the standardized
way of has_feature on displays side.
No functional change and no manual interaction to generate
this patch.

Restore our saved values for backlight. This way even with fastset on
S4 resume we will correctly restore the backlight to the active values.
Changes since v1:
- Call enable_backlight() when backlight.level is set. On suspend
backlight.enabled is always cleared, this makes it not a good
indicator. Also check for crtc->state->active.
Changes since v2:
- Use the new update_pipe() callback to run this on resume as well.

The display engine has 2 dithering enable bits which both need to be set
for dithering to happen, 1 in the PIPECONF register which is taken care of
by i9xx_set_pipeconf() and a second bit at the encoder level.
The dsi code was not setting the encoder level dithering enable bit causing
dithering to be disabled, this commit fixes this.

There are 3 problems with the dsi code's pipe_bpp handling for 6 bpc
pixel-formats which this commit addresses:
1) It assumes that the pipe_bpp is the same as the bpp going over the dsi
lanes. This assumption is not valid for MIPI_DSI_FMT_RGB666, where pipe_bpp
should be 18 so that we do proper dithering but we actually send 24 bpp
over the dsi lanes (MIPI_DSI_FMT_RGB666_PACKED sends 18 bpp).
This assumption is enforced by an assert in *_dsi_get_pclk(). This assert
triggers on the initial hw-state readback on BYT/CHT devices which use
MIPI_DSI_FMT_RGB666, such as the Prowise PT301 tablet. PIPECONF is set to
6BPC / 18 bpp by the GOP, while mipi_dsi_pixel_format_to_bpp() returns 24.
This commits switches the calculations in *_dsi_get_pclk() to use the bpp
from mipi_dsi_pixel_format_to_bpp(intel_dsi->pixel_format) which
returns the bpp going over the mipi lanes and drops the assert.
2) On BXT bxt_dsi_get_pipe_config() wrongly overrides the pipe_bpp which
i9xx_get_pipe_config() reads from PIPECONF with the return value from
mipi_dsi_pixel_format_to_bpp(). This avoids the assert from 1. but is wrong
since the pipe is actually running at the value configured in PIPECONF.
This commit drops the override of pipe_bpp from bxt_dsi_get_pipe_config().
3) The dsi encoder's compute_config() never assigns a value to pipe_bpp,
unlike most other encoders. Falling back on compute_baseline_pipe_bpp()
which always picks 24. 24 is only correct for MIPI_DSI_FMT_RGB88 for the
others we should use 18 bpp so that we correctly do 6bpc color dithering.
This commit adds code to intel_dsi_compute_config() to properly set
pipe_bpp based on intel_dsi->pixel_format.

Something that I completely missed when implementing the new MST VCPI
atomic helpers is that with those helpers, there's technically a chance
of us having to grab additional modeset locks in ->compute_config() and
furthermore, that means we have the potential to hit a normal modeset
deadlock. However, because ->compute_config() only returns a bool this
means we can't return -EDEADLK when we need to drop locks and try again
which means we end up just failing the atomic check permanently. Whoops.
So, fix this by modifying ->compute_config() to pass down an actual
error code instead of a bool so that the atomic check can be restarted
on modeset deadlocks.
Thanks to Ville Syrjälä for pointing this out!
Changes since v1:
* Add some newlines
* Return only -EINVAL from hsw_crt_compute_config()
* Propogate return code from intel_dp_compute_dsc_params()
* Change all of the intel_dp_compute_link_config*() variants
* Don't miss if (hdmi_port_clock_valid()) branch in
intel_hdmi_compute_config()

The majority of runtime-pm operations are bounded and scoped within a
function; these are easy to verify that the wakeref are handled
correctly. We can employ the compiler to help us, and reduce the number
of wakerefs tracked when debugging, by passing around cookies provided
by the various rpm_get functions to their rpm_put counterpart. This
makes the pairing explicit, and given the required wakeref cookie the
compiler can verify that we pass an initialised value to the rpm_put
(quite handy for double checking error paths).

VBT appears to have two (or possibly three) ways to indicate the panel
rotation. The first is in the MIPI config block, but that apparenly
usually (maybe always?) indicates 0 degrees despite the actual panel
orientation. The second way to indicate this is in the general features
block, which can just indicate whether 180 degress rotation is used.
The third might be a separate rotation data block, but that is not
at all documented so who knows what it may contain.
Let's try the first two. We first try the DSI specicic VBT
information, and it it doesn't look trustworthy (ie. indicates
0 degrees) we fall back to the 180 degree thing. Just to avoid too
many changes in one go we shall also keep the hardware readout path
for now.
If this works for more than just my VLV FFRD the question becomes
how many of the panel orientation quirks are now redundant?

Let's make sure the DSI port is actually on before we go
poking at the plane register to determine which way
it's rotated. Otherwise we could be looking at a plane
that is feeding a HDMI port for instance.
And in order to read the plane register we need the power
well to be on. Make sure that is indeed the case. We'll
also make sure the plane is actually enabled before we
trust the rotation bit to tell us the truth.

checks to vlv_dsi.c instead, where we typically already have the
necessary if ladders.
Leave the static functions as-is for now; they could be renamed later if
needed.
No functional changes.
v2: use "gen7" prefix.
v3: use "vlv" and "bxt" prefixes, reduce the abstractions.

Starting from ICL or gen 11 we have a new DSI block which requires
completely different programming from the current implementation. Having
them in the same file would be confusing. Rename the current DSI and DSI
PLL implementation files as vlv_dsi.c and vlv_dsi_pll.c.
No functional changes.
v2: use "gen7" prefix.
v3: use "vlv" prefix.
