drm/i915: remove redundant ELD connector type update

2018-01-19T09:58:48+00:00

drm_edid_to_eld() sets ELD connector type since commit 1d1c36650752
("drm/edid: set ELD connector type in drm_edid_to_eld()"). Remove the
redundant update.

(Commit c945b8c14bb7 ("drm/edid: build ELD in drm_add_edid_modes()") and
commit d471ed04b487 ("drm/drivers: drop redundant drm_edid_to_eld()
calls") are also related.)

v2: Rebase, update commit message with commit references.

drm/drivers: drop redundant drm_edid_to_eld() calls

2017-11-07T15:43:35+00:00

drm_add_edid_modes() now fills in the ELD automatically, so the calls to
drm_edid_to_eld() are redundant. Remove them.

All the other places are obvious, but nv50 has detached
drm_edid_to_eld() from the drm_add_edid_modes() call.

drm/i915: always update ELD connector type after get modes

2017-09-20T07:36:34+00:00

drm_edid_to_eld() initializes the connector ELD to zero, overwriting the
ELD connector type initialized in intel_audio_codec_enable(). If
userspace does getconnector and thus get_modes after modeset, a
subsequent audio component i915_audio_component_get_eld() call will
receive an ELD without the connector type properly set. It's fine for
HDMI, but screws up audio for DP.

Always set the ELD connector type at intel_connector_update_modes()
based on the connector type. We can drop the connector type update from
intel_audio_codec_enable().

drm/i915: Mass convert dev->dev_private to to_i915(dev)

2016-07-04T11:54:07+00:00

Since we now subclass struct drm_device, we can save pointer dances by
noting the equivalence of struct drm_device and struct drm_i915_private,
i.e. by using to_i915().

drm/i915: Add "Automatic" mode for the "Broadcast RGB" property

2013-01-20T12:09:44+00:00

Add a new "Automatic" mode to the "Broadcast RGB" range property.
When selected the driver automagically selects between full range and
limited range output.

Based on CEA-861 [1] guidelines, limited range output is selected if the
mode is a CEA mode, except 640x480. Otherwise full range output is used.
Additionally DVI monitors should most likely default to full range
always.

As per DP1.2a [2] DisplayPort should always use full range for 18bpp, and
otherwise will follow CEA-861 rules.

NOTE: The default value for the property will now be "Automatic"
so some people may be affected in case they're relying on the
current full range default.

[2] VESA DisplayPort Ver.1.2a - 5.1.1.1 Video Colorimetry
