3ccddc3991 drm/fbdev: fix drm_fb_helper_deferred_io() build failure 
The drm_fb_helper_deferred_io() uses struct fb_deferred_io_pageref,
which isn't available without CONFIG_FB_DEFERRED_IO. Put the function
under corresponding #ifdef to fix build failure if deferred I/O isn't
enabled.

d284ccd858 drm/bridge: sii902x: Set input bus format based on bus-width 
Introduce a bus-width property to define the number of parallel RGB
input pins connected to the transmitter. The input bus formats are updated
accordingly. If the property is not specified, default to 24-bit bus-width.

11fc5ce6e2 accel/qaic: Pass string literal as format argument of alloc_workqueue() 
Recently I noticed that both gcc-14 and clang-18 report that passing
a non-string literal as the format argument of alloc_workqueue()
is potentially insecure.

E.g. clang-18 says:

.../qaic_drv.c:61:23: warning: format string is not a string literal (potentially insecure) [-Wformat-security]
   61 |         wq = alloc_workqueue(fmt, WQ_UNBOUND, 0);
      |                              ^~~
.../qaic_drv.c:61:23: note: treat the string as an argument to avoid this
   61 |         wq = alloc_workqueue(fmt, WQ_UNBOUND, 0);
      |                              ^
      |                              "%s",

It is always the case where the contents of fmt is safe to pass as the
format argument. That is, in my understanding, it never contains any
format escape sequences.

But, it seems better to be safe than sorry. And, as a bonus, compiler
output becomes less verbose by addressing this issue as suggested by
clang-18.

Also, change the name of the parameter of qaicm_wq_init from
fmt to name to better reflect it's purpose.

Compile tested only.

2063ca4248 drm/display: Drop obsolete dependency on COMPILE_TEST 
Since commit 0166dc11be ("of: make CONFIG_OF user selectable"), it
is possible to test-build any driver which depends on OF on any
architecture by explicitly selecting OF. Therefore depending on
COMPILE_TEST as an alternative is no longer needed.

To avoid reintroducing the randconfig bug originally fixed by commit
876271118a ("drm/display: Fix build error without CONFIG_OF"),
DRM_MSM which selects DRM_DISPLAY_DP_HELPER must explicitly depend
on OF. This is consistent with what all other DRM drivers are doing.

dadd28d414 drm/client: Add client-lib module 
Add drm_client_lib.ko to contain DRM's built-in client. Move the
existing client for fbdev emulation into the new module. Protect the
new module behind CONFIG_DRM_CLIENT_LIB.

The Kconfig rules separate the DRM drivers from the DRM clients. A
driver can opt into the default clients, but the user configures
each client individually. To do so, DRM drivers still select
DRM_CLIENT_SELECTION. The option is now a tristate that further
selects all dependencies of the enabled DRM clients. There's
a menu option for each client. Enabling at least one client also
selects DRM_CLIENT_SETUP, so that drivers call drm_client_setup().
New DRM clients should depend on DRM_CLIENT_SELECTION.

There are existing kernel options in drm_fb_helper.o, so leave this
file in the KMS-helper module for now.

v5:
- leave fbdev helpers in drm_kms_helper.ko for now
v3:
- fix commit changelog
v2:
- keep client code in core
- protect lib with DRM_CLIENT_LIB
- remove duplicate line from Makefile (Jocelyn)

bf17766f10 drm/client: Move suspend/resume into DRM client callbacks 
Suspend and resume is still tied to fbdev emulation. Modeset helpers
and several drivers call drm_fb_helper_set_suspend_unlocked() to inform
the fbdev client about suspend/resume events.

To make it work with arbitrary clients, add per-client callback
functions for suspend and resume. Implement them for fbdev emulation
with the existing drm_fb_helper_set_suspend_unlocked(). Then update
DRM's modeset helpers to call the new interface.

Clients that are not fbdev can now implement suspend/resume to their
requirements.

The callback parameter holds_console_lock is a workaround for i915,
radeon and xe, which possibly call the interface while having the
console lock acquired. Even though the commit doesn't modify these
drivers, it already adds the flag to avoid churn later on. New code
should not hold the console lock.

v4:
- clarify holds_console_lock in commit description (Jonathan)

df7e8b522a drm/client: Move client event handlers to drm_client_event.c

operations to client code. Moving them info a separate file will later
allow for a more fine-grained kernel configuration. For most of the
users it is sufficient to include <drm/drm_client_event.h> instead of
the full driver-side interface in <drm/drm_client.h>

v2:
- rename new files to drm_client_event.{c,h}

134e71bd1e drm/sched: Further optimise drm_sched_entity_push_job 
Having removed one re-lock cycle on the entity->lock in a patch titled
"drm/sched: Optimise drm_sched_entity_push_job", with only a tiny bit
larger refactoring we can do the same optimisation on the rq->lock.
(Currently both drm_sched_rq_add_entity() and
drm_sched_rq_update_fifo_locked() take and release the same lock.)

To achieve this we make drm_sched_rq_update_fifo_locked() and
drm_sched_rq_add_entity() expect the rq->lock to be held.

We also align drm_sched_rq_update_fifo_locked(),
drm_sched_rq_add_entity() and
drm_sched_rq_remove_fifo_locked() function signatures, by adding rq as a
parameter to the latter.

v2:
 * Fix after rebase of the series.
 * Avoid naming inconsistency between drm_sched_rq_add/remove. (Christian)

f93126f5d5 drm/sched: Re-group and rename the entity run-queue lock 
When writing to a drm_sched_entity's run-queue, writers are protected
through the lock drm_sched_entity.rq_lock. This naming, however,
frequently collides with the separate internal lock of struct
drm_sched_rq, resulting in uses like this:

	spin_lock(&entity->rq_lock);
	spin_lock(&entity->rq->lock);

Rename drm_sched_entity.rq_lock to improve readability. While at it,
re-order that struct's members to make it more obvious what the lock
protects.

It does not seem there is a need to set the current entity in FIFO mode
since ot only serves as being a "cursor" in round-robin mode. Even if
scheduling mode is changed at runtime the change in behaviour is simply
to restart from the first entity, instead of continuing in RR mode from
where FIFO left it, and that sounds completely fine.
