Add helper for initializing fbdev deferred I/O.
The cleanup could have happened in drm_fb_helper_fini(), but that would
have required me to set fb_info->fbdefio to NULL in a couple of drivers
before they call _fini() to avoid double defio cleanup. The problem is
that one of those is vboxvideo which lives in Greg's staging tree.
So I put the cleanup in drm_fb_helper_fbdev_teardown(), not perfect
but not that bad either.

We don't want people to accidentally stumble over there.
Also rename the plane helpers to legacy plane helpers. After Ville's
patch to make the clipping helper atomic and move it to
drm_atomic_helper.c there's nothing left in there that should be
useful for modern drivers.
v2: Laurent had a few questions around how state is added to
drm_atomic_state, tried to clarify that. And spotted another sentence
where the docs suggested subclassing.
v3: Small polish (Alex).

DK put some nice docs into the commit introducing driver private
state, but in the git history alone it'll be lost.
Also, since Ville remove the void* usage it's a good opportunity to
give the driver private stuff some tlc on the doc front.
Finally try to explain why the "let's just subclass drm_atomic_state"
approach wasn't the greatest, and annotate all those functions as
deprecated in favour of more standardized driver private states. Also
note where we could/should extend driver private states going forward
(atm neither locking nor synchronization is handled in core/helpers,
which isn't really all that great).
v2: Spelling and phrasing improvements (Alex, DK).

It thinks we want to document the __printf(2,0) annotion. Not sure we
want to teach it about all possible gcc-only flags, hence why I opted
for the cheap trick of just moving it ahead of the kerneldoc.
This is only a problem for static inline functions, since for
non-inline function the kerneldoc is in the .c file, but the special
annotations are all in the header.
Cc'ing kernel-doc maintainers as fyi.

PROBE_DEFER also uses system_wq to reprobe drivers, which means when
that again fails, and we try to flush the overall system_wq (to get
all the delayed connectore cleanup work_struct completed), we
deadlock.
Fix this by using just a single cleanup work, so that we can only
flush that one and don't block on anything else. That means a free
list plus locking, a standard pattern.
v2:
- Correctly free connectors only on last ref. Oops (Chris).
- use llist_head/node (Chris).
v3
- Add init_llist_head (Chris).

There are a set of values in the drm_display_info structure for each
connector which hold information derived from EDID. These are computed
in drm_add_display_info. Before this patch, that was only called in
drm_add_edid_modes. This meant that they were only set when EDID was
present and never reset when EDID was not, as happened when the
display was disconnected.
One of these fields, non_desktop, is used from
drm_mode_connector_update_edid_property, the function responsible for
assigning the new edid value to the application-visible property.
Various drivers call these two functions (drm_add_edid_modes and
drm_mode_connector_update_edid_property) in different orders. This
means that even when EDID is present, the drm_display_info fields may
not have been computed at the time that
drm_mode_connector_update_edid_property used the non_desktop value to
set the non_desktop property.
I've added a public function (drm_reset_display_info) that resets the
drm_display_info field values to default values and then made the
drm_add_display_info function public. These two functions are now
called directly from drm_mode_connector_update_edid_property so that
the drm_display_info fields are always computed from the current EDID
information before being used in that function.
This means that the drm_display_info values are often computed twice,
once when the EDID property it set and a second time when EDID is used
to compute modes for the device. The alternative would be to uniformly
ensure that the values were computed once before being used, which
would require that all drivers reliably invoke the two paths in the
same order. The computation is inexpensive enough that it seems more
maintainable in the long term to simply compute them in both paths.
The API to drm_add_display_info has been changed so that it no longer
takes the set of edid-based quirks as a parameter. Rather, it now
computes those quirks itself and returns them for further use by
drm_add_edid_modes.
This patch also includes a number of 'const' additions caused by
drm_mode_connector_update_edid_property taking a 'const struct edid *'
parameter and wanting to pass that along to drm_add_display_info.
v2: after review by Daniel Vetter <daniel.vetter@ffwll.ch>
Removed EXPORT_SYMBOL_GPL for drm_reset_display_info and
drm_add_display_info.
Added FIXME in drm_mode_connector_update_edid_property about
potentially merging that with drm_add_edid_modes to avoid
the need for two driver calls.

Use drm_fb_cma_fbdev_init_with_funcs() and drm_fb_cma_fbdev_fini() which
relies on the fact that drm_device holds a pointer to the drm_fb_helper
structure. This means that the driver doesn't have to keep track of that.
Also use the drm_fb_helper functions directly.

Add functions drm_fb_cma_fbdev_init(), drm_fb_cma_fbdev_fini() and
drm_fb_cma_fbdev_init_with_funcs(). These functions relies on the fact
that the drm_fb_helper struct is stored in dev->drm_fb_helper_private
so drivers don't need to store it.

This is the only part of the scheduler which must not be called from
different drivers. Move it to module init/exit so it is done a single

This moves and renames the AMDGPU scheduler to a common location in DRM
in order to facilitate re-use by other drivers. This is mostly a straight
forward rename with no code changes.
One notable exception is the function to_drm_sched_fence(), which is no
longer a inline header function to avoid the need to export the
drm_sched_fence_ops_scheduled and drm_sched_fence_ops_finished structures.

drm: locking&new iterators for connector_list
we've went to extreme lengths to make sure connector iterations works
in any context, without introducing any additional locking context.
This worked, except for a small fumble in the implementation:
When we actually race with a concurrent connector unplug event, and
our temporary connector reference turns out to be the final one, then
everything breaks: We call the connector release function from
whatever context we happen to be in, which can be an irq/atomic
context. And connector freeing grabs all kinds of locks and stuff.
Fix this by creating a specially safe put function for connetor_iter,
which (in this rare case) punts the cleanup to a worker.

Apply the "panel orientation" drm connector prop to the primary plane so
that fbcon and fbdev using userspace programs display the right way up.
Changes in v3:
-Use a rotation member in struct drm_fb_helper_crtc and set that from
drm_setup_crtcs instead of looping over all crtc's to find the right one
later
-Since we now no longer look at rotation quirks directly in the fbcon
code, set fb_info.fbcon_rotate_hint when the panel is not mounted upright
and we cannot use hardware rotation
Changes in v4:
-Make drm_fb_helper_init() init drm_fb_helper_crtc.rotation to
DRM_MODE_ROTATE_0 for all crtcs, so that we do not end up setting the
plane_state's rotation to an invalid value for disabled crtcs
(caught by Fi.CI)
Changes in v5:
-Only use hardware (crtc primary plane) rotation for DRM_ROTATE_180,
90 / 270 degree rotation requires special handling which we lack atm
-Add a TODO comment for 90 / 270 degree hardware rotation
-Add some comments to better document the default case when mapping
sw_rotations to fbcon_rotate_hints

On some devices the LCD panel is mounted in the casing in such a way that
the up/top side of the panel does not match with the top side of the
device (e.g. it is mounted upside-down).
This commit adds the necessary infra for lcd-panel drm_connector-s to
have a "panel orientation" property to communicate how the panel is
orientated vs the casing.
Userspace can use this property to check for non-normal orientation and
then adjust the displayed image accordingly by rotating it to compensate.
Changes in v2:
-Store panel_orientation in drm_display_info, so that drm_fb_helper.c can
access it easily
-Have a single drm_connector_init_panel_orientation_property rather then
create and attach functions. The caller is expected to set
drm_display_info.panel_orientation before calling this, then this will
check for platform specific quirks overriding the panel_orientation and if
the panel_orientation is set after this then it will attach the property.
Changes in v6:
-Use an enum (with kerneldoc) rather then #defines for
DRM_MODE_PANEL_ORIENTATION_*

Some x86 clamshell design devices use portrait tablet screens and a display
engine which cannot rotate in hardware, so the firmware just leaves things
as is and we cannot figure out that the display is oriented non upright
from the hardware.
So at least on x86, we need a quirk table for this. This commit adds a DMI
based quirk table which is initially populated with 5 such devices: Asus
T100HA, GPD Pocket, GPD win, I.T.Works TW891 and the VIOS LTH17.
This quirk table will be used by the drm code to let userspace know that
the display is not mounted upright inside the devices case through a new
panel orientation drm-connector property, as well as to tell fbcon to
rotate the console so that it shows the right way up.
Changes in v5:
-Add a kernel-doc comment documenting drm_get_panel_orientation_quirk()
-Remove board_* matches from the dmi-matches for the VIOS LTH17 laptop,
keeping only the (identical) sys_vendor and product_name matches.
This is necessary because an older version of the bios has
board_vendor set to VOIS instead of VIOS
Changes in v6:
-Add reference to added kernel-docs in Documentation/gpu/drm-kms-helpers.rst
