Daniel Vetter d78aa65067 drm: Add drm/drm_util.h header file
We have a bunch of neat little macros all over the place which should
move to kernel.h. But some of them died in bikesheds on lkml, and we
need a decent home for them.

Start out by moving the for_each_if macro there.

v2: Rename to drm_util.h instead (Dave&Sean)

Gerd Hoffmann 6960e6da9c drm: fix drm_mode_addfb() on big endian machines.
Userspace on big endian machhines typically expects the ADDFB ioctl
returns a big endian framebuffer.  drm_mode_addfb() will call
drm_mode_addfb2() unconditionally with little endian DRM_FORMAT_*
values though, which is wrong.  This patch fixes that.

Drivers (both kernel and xorg) have quirks in place to deal with the
broken drm_mode_addfb() behavior.  Because of this we can't just change
drm_mode_addfb() behavior for everybody without breaking things.  Add
the quirk_addfb_prefer_host_byte_order field to mode_config, so drivers
can opt-in.

Lowry Li a5ec8332d4 drm: Add per-plane pixel blend mode property
Pixel blend modes represent the alpha blending equation
selection, describing how the pixels from the current
plane are composited with the background.

Adds a pixel_blend_mode to drm_plane_state and a
blend_mode_property to drm_plane, and related support
functions.

Defines three blend modes in drm_blend.h.

Changes since v1:
 - Moves the blending equation into the DOC comment
 - Refines the comments of drm_plane_create_blend_mode_property to not
   enumerate the #defines, but instead the string values
 - Uses fg.* instead of pixel.* and plane_alpha instead of plane.alpha
Changes since v2:
 - Refines the comments of drm_plane_create_blend_mode_property:
      1) Puts the descriptions (after the ":") on a new line
      2) Adds explaining why @supported_modes need PREMUL as default
Changes since v3:
 - Refines drm_plane_create_blend_mode_property(). drm_property_add_enum()
   can calculate the index itself just fine, so no point in having the
   caller pass it in.
 - Since the current DRM assumption is that alpha is premultiplied
   as default, define DRM_MODE_BLEND_PREMULTI as 0 will be better.
 - Refines some comments.
Changes since v4:
 - Adds comments in drm_blend.h.
 - Removes setting default value in drm_plane_create_blend_mode_property()
   as it is already in __drm_atomic_helper_plane_reset().
 - Fixes to use state->pixel_blend_mode instead of using
   plane->state->pixel_blend_mode in reset function.
 - Rebases on drm-misc-next.

Daniel Vetter e296de926d drm/syncobj: Drop add/remove_callback from driver interface
This is used for handling future fences. Currently no driver use
these, and I think given the new timeline fence proposed by KHR it
would be better to have a more abstract interface for future fences.
Could be something simple like a struct dma_future_fence plus a
function to add a callback or wait for the fence to materialize.

Then syncobj (and anything else really) could grow new functions to
expose these two drivers. Normal dma_fence would then keep the nice
guarantee that they will always signal (and through ordering, be
deadlock free). dma_future_fence would then be the tricky one.

This also fixes sphinx complaining about the kerneldoc.

Alexandru Gheorghe 7f4de52100 drm/atomic: Add __drm_atomic_helper_plane_reset
There are a lot of drivers that subclass drm_plane_state, all of them
duplicate the code that links together the plane with plane_state.

On top of that, drivers that enable core properties also have to
duplicate the code for initializing the properties to their default
values, which in all cases are the same as the defaults from core.

Change since v1:
- Make it consistent with the other helpers and require that both
  plane and state not be NULL, suggested by Boris Brezillon and

A bit larger this time around, due to introduction of "dpu1" support
for the display controller in sdm845 and beyond.  This has been on

~30kloc), and all my review complaints have been addressed, so I'd be
happy to see this upstream so further feature work can procede on top
of upstream.

Also includes the gpu coredump support, which should be useful for
debugging gpu crashes.  And various other misc fixes and such.

Takashi Iwai a57942bfdd ALSA: hda: Make audio component support more generic
This is the final step for more generic support of DRM audio
component.  The generic audio component code is now moved to its own
file, and the symbols are renamed from snd_hac_i915_* to
snd_hdac_acomp_*, respectively.  The generic code is enabled via the
new kconfig, CONFIG_SND_HDA_COMPONENT, while CONFIG_SND_HDA_I915 is
kept as the super-class.

Along with the split, three new callbacks are added to audio_ops:
pin2port is for providing the conversion between the pin number and
the widget id, and master_bind/master_unbin are called at binding /
unbinding the master component, respectively.  All these are optional,
but used in i915 implementation and also other later implementations.

A note about the new snd_hdac_acomp_init() function: there is a slight
difference between this and the old snd_hdac_i915_init().  The latter
(still) synchronizes with the master component binding, i.e. it
assures that the relevant DRM component gets bound when it returns, or
gives a negative error.  Meanwhile the new function doesn't
synchronize but just leaves as is.  It's the responsibility by the
caller's side to synchronize, or the caller may accept the
asynchronous binding on the fly.

Takashi Iwai ae891abe7c drm/i915: Split audio component to a generic type
For allowing other drivers to use the DRM audio component, rename the
i915_audio_component_* with drm_audio_component_*, and split the
generic part into drm_audio_component.h.  The i915 specific stuff
remains in struct i915_audio_component, which contains
drm_audio_component as the base.

The license of drm_audio_component.h is kept to MIT as same as the the
original i915_component.h.

This is a preliminary change for further development, and no
functional changes by this patch itself, merely code-split and
renames.

Lyude Paul a18b219294 drm/dp_helper: Add DP aux channel tracing
This is something we've needed for a very long time now, as it makes
debugging issues with faulty MST hubs along with debugging issues
regarding us interfacing with hubs correctly vastly easier to debug.
Currently this can actually be done if you trace the i2c devices for DP
using ftrace but that's significantly less useful for a couple of
reasons:

- Tracing the i2c devices through ftrace means all of the traces are
  going to contain a lot of "garbage" output that we're sending over the
  i2c line. Most of this garbage comes from retrying transactions, DRM's
  helper library adding extra transactions to work around bad hubs, etc.
- Having a user set up ftrace so that they can provide debugging
  information is a lot more difficult then being able to say "just boot
  with drm.debug=0x100"
- We can potentially expand upon this tracing in the future to print
  debugging information in regards to other DP transactions like MST
  sideband transactions

This is inspired by a patch Rob Clark sent to do this a long time back.
Neither of us could find the patch however, so we both assumed it would
probably just be easier to rewrite it anyway.

Daniel Vetter c555f02371 drm: drop _mode_ from update_edit_property()
Just makes it longer, and for most things in drm_connector.[hc] we
just use the drm_connector_ prefix. Done with sed + a bit of manual
fixup for the indenting.

Daniel Vetter 92e1d26324 drm/doc: polish for sturct drm_connector
- switch everything over to inline comments
- add notes about locking, links to functions and other related stuff
- also include a note about Ville's soon-to-be-merged
  drm_connector_for_each_possible_encoder().

Also check that all the hyperlinks in drm_connector.h work and fix
them as needed.
