b9936121d9 drm/i915/dp: Extract drm_dp_read_dpcd_caps()
Since DP 1.3, it's been possible for DP receivers to specify an
additional set of DPCD capabilities, which can take precedence over the
capabilities reported at DP_DPCD_REV.

Basically any device supporting DP is going to need to read these in an
identical manner, in particular nouveau, so let's go ahead and just move
this code out of i915 into a shared DRM DP helper that we can use in
other drivers.

v2:
* Remove redundant dpcd[DP_DPCD_REV] == 0 check
* Fix drm_dp_dpcd_read() ret checks

7801f3b792 drm/i915/display: prefer dig_port to reference intel_digital_port
We have a mix of dport, intel_dport, intel_dig_port and dig_port to
reference a intel_digital_port struct. Numbers are around

5	intel_dport
36	dport
479	intel_dig_port
352	dig_port

Since we already removed the intel_ prefix from most of our other
structs, do the same here and prefer dig_port.

v2: rename everything in i915, not just a few display sources and
reword commit message (from Matt Roper)

ce58867ee1 drm/i915: Fix enabled infoframe states of lspcon
Compared to implementation of DP and HDMI's encoder->infoframes_enabled,
the lspcon's implementation returns its active state. (we expect enabled
infoframe states of HW.) It leads to pipe state mismatch error
when ddi_get_config is called.

Because the current implementation of lspcon is not ready to support
readout infoframes, we need to return 0 here.

In order to support readout to lspcon, we need to implement read_infoframe
and infoframes_enabled. And set_infoframes also have to set an appropriate
bit on crtc_state->infoframes.enable

1d455f8de8 drm/i915: rename intel_drv.h to display/intel_display_types.h
Everything about the file is about display, and mostly about types
related to display. Move under display/ as intel_display_types.h to
reflect the facts.

There's still plenty to clean up, but start off with moving the file
where it logically belongs and naming according to contents.

v2: fix the include guard name in the renamed file

379bc10023 drm/i915: move modesetting output/encoder code under display/
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
