294bbd1f26 drm/panic: Add support for drawing a monochrome graphical logo 
Re-use the existing support for boot-up logos to draw a monochrome
graphical logo in the DRM panic handler.  When no suitable graphical
logo is available, the code falls back to the ASCII art penguin logo.

Note that all graphical boot-up logos are freed during late kernel
initialization, hence a copy must be made for later use.

a63ee07883 drm/panic: Fix uninitialized drm_scanout_buffer.set_pixel() crash 
No implementations of drm_plane_helper_funcs.get_scanout_buffer() fill
in the optional drm_scanout_buffer.set_pixel() member.  Hence the member
may contain non-zero garbage, causing a crash when deferencing it during
drm panic.

Fix this by pre-initializing the drm_scanout_buffer object before
calling drm_plane_helper_funcs.get_scanout_buffer().

f85376c890 drm/ttm/tests: Let ttm_bo_test consider different ww_mutex implementation. 
PREEMPT_RT has a different locking implementation for ww_mutex. The
base mutex of struct ww_mutex is declared as struct WW_MUTEX_BASE. The
latter is defined as `mutex' for non-PREEMPT_RT builds and `rt_mutex'
for PREEMPT_RT builds.

Using mutex_lock() directly on the base mutex in
ttm_bo_reserve_deadlock() leads to compile error on PREEMPT_RT.

The locking-selftest has its own defines to deal with this and it is
probably best to defines the needed one within the test program since
their usefulness is limited outside of well known selftests.

Provide ww_mutex_base_lock() which points to the correct function for
PREEMPT_RT and non-PREEMPT_RT builds.

This will make it easier for Linux distributions to enable drm_panic
by disabling VT_CONSOLE, and keeping fbcon terminal.
The only drawback is that fbcon won't display the boot kmsg, so it
should rely on userspace to do that.

41474d25be drm: Add DRM_MODE_TV_MODE_MONOCHROME 
Add this as a value for enum_drm_connector_tv_mode, represented
by the string "Mono", to generate video with no colour encoding
or bursts. Define it to have no pedestal (since only NTSC-M calls
for a pedestal).

Change default mode creation to acommodate the new tv_mode value
which comprises both 525-line and 625-line formats.

0743dafefd drm: zynqmp_kms: Fix AUX bus not getting unregistered 
drm_encoder_cleanup is responsible for calling drm_bridge_detach for
each bridge attached to the encoder. zynqmp_dp_bridge_detach is in turn
responsible for unregistering the AUX bus. However, we never ended up
calling drm_encoder_cleanup in the remove or error paths, so the AUX bus
would stick around after the rest of the driver had been removed.

I don't really understand why drm_mode_config_cleanup doesn't call
drm_encoder_cleanup for us. It will call destroy (which for
simple_encoder is drm_encoder_cleanup) on encoders in the mode_config's
encoder_list.

Should drm_encoder_cleanup get called before or after
drm_atomic_helper_shutdown?

When the bridge is attached with the 'DRM_BRIDGE_ATTACH_NO_CONNECTOR'

It also returns MODE_OK for all modes without actually checking the

Note, to simplify implementation, there can be only one bridge in a
