drm: dw-hdmi: gate audio clock from the I2S enablement callbacks
Currently, the audio sampler clock is enabled from dw_hdmi_setup() at
step E. and is kept enabled for later use. This clock should be enabled
and disabled along with the actual audio stream and not always on (that
is bad for PM). Furthermore, as described by the datasheet, the I2S
variant needs to gate/ungate the clock when the stream is
enabled/disabled.
This commit adds a parameter to hdmi_audio_enable_clk() that controls
when the audio sample clock must be enabled or disabled. Then, it adds
the call to this function from dw_hdmi_i2s_audio_enable() and
dw_hdmi_i2s_audio_disable().

This commit introduces two callbacks, one for each variant.

To work around that and allow more memory to be reserved for graphics,
allocate a single BO to store tile state data arrays and tile

All the error codes we (ab)use are strictly not the right ones (since

look up an object throughout drm, so let's use it in the cma helpers,
too.
Note that this does change uabi for some drivers, but that shouldn't
ba a problem:
- other drivers (e.g. i915) already return ENOENT for invalid gem bo
- userspace tends to only check for errors, not specific ones (except
when ioctl restarting is needed)
- if the gem bo isn't there a previous step (either creating or
importing it) failed already, this situation should always be a
userspace bug.
Changing it does help with debugging userspace bugs though, by making
error reporting more consistent.

drm/vmwgfx: Fix fbdev emulation using legacy functions
I've broken this by removing the backoff handling from the
set_config2atomic helper in
commit

drm/atomic-helper: Remove the backoff hack from set_config
Fixing this properly would mean we get to wire the acquire_ctx all the
way through vmwgfx fbdev code, and doing the same was tricky for the
shared fbdev layer. Probably much better to look into refactoring the
entire code to use the helpers, but since that's not a viable
long-term solution fix the issue by open-coding a vmwgfx version of
set_config, that does the legacy backoff dance internally.
Note: Just compile-tested. The idea is to take
drm_mode_set_config_internal(), remove the "is this a legacy driver"
check, and whack the drm_atomic_legacy_backoff trickery at the end.
Since drm_atomic_legacy_backoff is for atomic commits only we need to
open-code it.

drm/atomic: Acquire connection_mutex lock in drm_helper_probe_single_connector_modes, v4.
mode_valid() called from drm_helper_probe_single_connector_modes()

Some implementations of detect() already lock all state,

For the callbacks, it will always be non-zero. To allow callers
not to worry about this, drm_helper_probe_detect_ctx is added

Changes since v1:
- Always set ctx parameter.
Changes since v2:
- Always take connection_mutex when probing.
Changes since v3:
- Remove the ctx from intel_dp_long_pulse, and add
WARN_ON(!connection_mutex) (danvet)

drm/fb-helper: Give up on kgdb for atomic drivers
It just doesn't work. It probably stopped working way, way before that
(e.g. i915 grabbed random mutexes all over in modeset code at least
since gen6), but with atomic and all the ww_mutex stuff it's indeed
hopeless.
Remove ->mode_set_base_atomic from the 2 atomic drivers (i915 and
nouveau) that still had one (both had dummy implementations already
anyway), and shunt atomic drivers in the helpers debug_enter/leave
functions.
I'll leave the code in for radeon and amdgpu, but I think as soon as
amdgpu is atomic we should think about just ripping it out. Only
having it around for radeon and pre-nv50 is rather pointless. This
would also allow us to nuke all that code from fbdev.
Funny part is that _all_ kms drivers set this hook, despite that no
one else provides the required ->mode_set_base_atomic implementation.
The reason I'm jumping on this is that I want to wire up a full
acquire ctx for the benefit of atomic drivers, everywhere. And the
debug_enter/leave implementations call ->gamma_set. And there's just
no way ever we can create an acquire_ctx in the nmi context of kgdb.
