The driver configures mostly Pixel PLL from the clock cached in

2eb747a598 drm/omap: Clean up deadcode functions 
dispc_enable_fifomerge() last use was removed by 2012's
commit 85099f11bd ("Revert "OMAPDSS: APPLY: add fifo merge support
funcs"")

dispc_has_writeback(), dispc_wb_get_framedone_irq(), dispc_wb_go(),
dispc_wb_go_busy() and dispc_wb_setup() were changed from statics
to public symbols and unwired from a structure by 2020's
commit dac62bcafe ("drm/omap: remove dispc_ops")
but didn't have any users.

dispc_mgr_get_clock_div() got renamed from dispc_get_clock_div()
and it's last use was removed in 2011 by commit
42c9dee821 ("OMAP: DSS2: Remove FB_OMAP_BOOTLOADER_INIT support")

3ae80b3757 drm/sched: warn about drm_sched_job_init()'s partial init 
drm_sched_job_init()'s name suggests that after the function succeeded,
parameter "job" will be fully initialized. This is not the case; some
members are only later set, notably drm_sched_job.sched by
drm_sched_job_arm().

Document that drm_sched_job_init() does not set all struct members.

Document the lifetime of drm_sched_job.sched.

2320c9e6a7 drm/sched: memset() 'job' in drm_sched_job_init() 
drm_sched_job_init() has no control over how users allocate struct
drm_sched_job. Unfortunately, the function can also not set some struct
members such as job->sched.

This could theoretically lead to UB by users dereferencing the struct's
pointer members too early.

It is easier to debug such issues if these pointers are initialized to
NULL, so dereferencing them causes a NULL pointer exception.
Accordingly, drm_sched_entity_init() does precisely that and initializes
its struct with memset().

Initialize parameter "job" to 0 in drm_sched_job_init().

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)
