2616be2eac drm/i915/dp: make intel_dp_pack_aux() static again 
The last user of intel_dp_pack_aux() outside intel_dp_aux.c got removed
in commit ad26451a79 ("drm/i915/display: Drop PSR support from HSW and
BDW"). Make the function static again.

Rename the pack/unpack functions to follow the usual naming conventions
while at it.

43571e15c0 drm/i915: Drop unused _PORT3 and _PORT4 TC phy register offsets 
All MG/DKL PHY register regions are evenly spaced offset-wise (0x168000,
0x169000, 0x16A000, 0x16B000) so the _MMIO_PORT() macro we use to access
their registers only needs the first two offsets.  We can drop the
_PORT3 and _PORT4 offsets which are never directly referenced.

202b1f4c12 drm/i915/gt: Move engine registers to their own header 
Let's continue breaking up and cleaning up the massive i915_reg.h file

to their own header.

There are probably a bunch of other "engine registers" that we haven't
moved yet (especially those that belong to the render engine in the
0x2??? range), but this is a relatively straightforward first step.

798c5daf3c drm/i915/fbc: Remember to update FBC state even when not reallocating CFB 
We mustn't forget to update our FBC state even if we don't have
to reallocate the CFB. Otherwise we won't refresh our notion
of what eg. the new fence or the new override CFB stride
should be. Using the wrong CFB stride in particular can cause
underruns and could even corrupt other stuff in stolen.

825ca9ed1c drm: Always include the debugfs dentry in drm_crtc 
Remove the counterproductive CONFIG_DEBUG_FS ifdef and just include
the debugfs dentry in drm_crtc always. This way we don't need
annoying ifdefs in the actual code with DEBUGFS=n. Also we don't
have these ifdefs around any of the other debugfs dentries either
so can't see why drm_crtc should be special.

This fixes the i915 DEBUGFS=n build because I assumed the dentry
would always be there.

637088a21e drm/i915/backlight: Make ext_pwm_disable_backlight() call intel_backlight_set_pwm_level() 
At least the Bay Trail LPSS PWM controller used with DSI panels on many
Bay Trail tablets seems to leave the PWM pin in whatever state it was
(high or low) ATM that the PWM gets disabled. Combined with some panels
not having a separate backlight-enable pin this leads to the backlight
sometimes staying on while it should not (when the pin was high during
PWM-disabling).

First calling intel_backlight_set_pwm_level() will ensure that the pin
is always low (or high for inverted brightness panels) since the passed
in duty-cycle is 0% (or 100%) when the PWM gets disabled fixing the
backlight sometimes staying on.

With the exception of ext_pwm_disable_backlight() all other
foo_disable_backlight() functions call intel_backlight_set_pwm_level()
already before disabling the backlight, so this change also aligns
ext_pwm_disable_backlight() with all the other disable() functions.
