Several source files include drm_crtc_helper.h without needing it or

<title>drm/amdgpu: Retry DDC probing on DVI on failure if we got an HPD interrupt</title>

<id>90f56611fc5b54d55e94ded1d494d6090649bdb6</id>
<content type='text'>
HPD signals on DVI ports can be fired off before the pins required for
DDC probing actually make contact, due to the pins for HPD making
contact first. This results in a HPD signal being asserted but DDC
probing failing, resulting in hotplugging occasionally failing.

Rescheduling the hotplug work for a second when we run into an HPD
signal with a failing DDC probe usually gives enough time for the rest
of the connector's pins to make contact, and fixes this issue.

This partially reverts 20543be93ca45968f344261c1a997177e51bd7e1.

Calling drm_connector_update_edid_property() in
amdgpu_connector_free_edid() causes a noticeable pause in
the system every 10 seconds on polled outputs so revert this
part of the change.

Rename dp/ to display/ to account for additional display-related
helpers, such as HDMI. Update all related include statements. No
functional changes.

Various drivers, such as i915 and amdgpu, use similar naming scheme
by putting code for video-output standards into a local display/
directory. The new directory's name is aligned with this convention.

<title>drm/amdgpu: Use drm_mode_copy()</title>

struct drm_display_mode embeds a list head, so overwriting
the full struct with another one will corrupt the list
(if the destination mode is on a list). Use drm_mode_copy()
instead which explicitly preserves the list head of
the destination mode.

Even if we know the destination mode is not on any list
using drm_mode_copy() seems decent as it sets a good
example. Bad examples of not using it might eventually
get copied into code where preserving the list head
actually matters.

Obviously one case not covered here is when the mode
itself is embedded in a larger structure and the whole
structure is copied. But if we are careful when copying
into modes embedded in structures I think we can be a
little more reassured that bogus list heads haven't been
propagated in.

<title>drm/edid: Split deep color modes between RGB and YUV444</title>

The current code assumes that the RGB444 and YUV444 formats are the
same, but the HDMI 2.0 specification states that:

   The three DC_XXbit bits above only indicate support for RGB 4:4:4 at
   that pixel size. Support for YCBCR 4:4:4 in Deep Color modes is
   indicated with the DC_Y444 bit. If DC_Y444 is set, then YCBCR 4:4:4
   is supported for all modes indicated by the DC_XXbit flags.

So if we have YUV444 support and any DC_XXbit flag set but the DC_Y444
flag isn't, we'll assume that we support that deep colour mode for
YUV444 which breaks the specification.

In order to fix this, let's split the edid_hdmi_dc_modes field in struct
drm_display_info into two fields, one for RGB444 and one for YUV444.
