Just for the struct drm_mode_object base class. The header file was
already partially extracted to help untangle the include loops.
v2:
- Also move the generic get/set property ioctls. At first this seemed
like a bad idea since it requires making drm_mode_crtc_set_obj_prop
non-static. But eventually that will get split away too (like
the connector version already is) for both crtc and planes. Hence I
reconsidered.
- drm_mode_object.[hc] instead of drm_modeset.[hc], which requires
renaming the drm_modeset.h header I already started building up.
This is more consistent (matches the name of the main structure),
and I want to be able to use drm_modeset.[hc] for the basic modeset
init/cleanup functionality like drm_mode_config_init.

Drivers may set the NO_DISABLE_AFTER_MODESET flag in the 'flags' parameter
of the helper drm_atomic_helper_commit_planes() if the relevant display
controllers(e.g., IPUv3 for imx-drm) require to disable a CRTC's planes
when the CRTC is disabled. The helper would skip the ->atomic_disable
call for a plane if the CRTC of the old plane state needs a modesetting
operation. Of course, the drivers need to disable the planes in their CRTC
disable callbacks since no one else would do that.

Currently, the helper drm_atomic_helper_disable_planes_on_crtc() calls
->atomic_disable for all planes _to be_ enabled on a particular CRTC.
This is obviously wrong for those planes which are not scanning out frames
when the helper is called. Instead, it's sane to disable active planes
of old_crtc_state in the helper.

Some display controllers need plane(s) to be disabled together with
the relevant CRTC, e.g., the IPUv3 display controller for imx-drm.
This patch adds atomic_disable CRTC helper callback so that
old_crtc_state(as a parameter of the callback) could be used
to get the active plane(s) of the old CRTC state for disable operation.

Up to now, once a bridge has been attached to a DRM device, it cannot
be undone.
In particular you couldn't rmmod/insmod a DRM driver that uses a bridge,
because the bridge would remain bound to the first (dead) driver instance.
This patch fixes this by introducing drm_encoder_detach() and a ->detach
callback in drm_bridge_funcs for the bridge to be notified about detaches.
It's DRM/KMS driver responsibility to call drm_encoder_detach().
While adding the bridge detach callback, with its kerneldoc, I also added
kerneldoc for attach callback.
Few other kerneldocs fixes around there are included.

The *only* known user of GETCLIENT is libva, which uses it to check
whether its own context is authenticated. It used to iterate all clients,
look for one that matches its own pid and then check its state.
The entire purpose for us to still have a GETCLIENT implementation is to
serve libva. So lets not pretend we do anything else: Make this function
return information on the caller's context only, fake the PID to the
caller's pid so they always match, and just fill in the "authenticated"
bit, nothing else.
This patch reduces the complexity of GETCLIENT to a bare minimum, avoids
any dependency on priv->uid or priv->pid (allows us to get rid of them),
and makes libva happy by always *exactly* returning the information it
wants.

The legacy DRI1 drivers expose highly broken interfaces to user-space. No
modern system should enable them, or you will effectively allow user-space
to circumvent most of your kernel security measures. The DRI1 kernel APIs
are simply broken.
User-space can always use vesafb/efifb/simplefb and friends to get working
graphics.
Lets hide the old drivers behind CONFIG_BROKEN. In case they turn out to
be still used (really?), we can easily revert this and figure out a way to
move them out of sight (e.g., moving all DRI1 drivers to
drivers/gpu/dri1/).

itself into common PSR driver, encoder have implement the 'psr_set'
callback which use the set PSR state in hardware side.
Crtc driver would call the enable/disable interfaces when vblank is
enable/disable, after that the common PSR driver would call the encoder
registered callback to set the PSR state.
Fb driver would call the flush interface in 'fb->dirty' callback, this
helper function would force all PSR enabled encoders to exit from PSR

we can set the line number to vop line_flag register, and then vop would
generate a line_flag interrupt for it.
For example eDP PSR function is interested in the vertical blanking
period, then driver could set the line number to zero.
This patch have exported a symbol that allow other driver to listen the
line flag event with given timeout limit:
- rockchip_drm_wait_line_flag()

Instead of just preparing the panel on bind, actually prepare/unprepare
during modeset/disable. The panel must be prepared in order to read hpd
status and edid, so we need to keep state around the prepares in order
to ensure we don't accidentally turn the panel off at the wrong time.

There are two VOP in rk3399 chip, respectively VOP_BIG and VOP_LIT.
most registers layout of this two vop is same, their framework are both
VOP_FULL, the Major differences of this two is that:
VOP_BIG max output resolution is 4096x2160.
VOP_LIT max output resolution is 2560x1600
VOP_BIG support four windows.
VOP_LIT only support two windows.
RK3399 vop register layout is similar with rk3288, so some feature
can reuse with rk3288.

This adds a function that also takes the console lock before calling
fb_set_suspend() in contrast to drm_fb_helper_set_suspend() which is

Resume is run asynchronously using a worker if the console lock is
already taken. This is modelled after the i915 driver.

the final version moved the flags and the associated #defines around
so they were adjacent; unfortunately, they ended up between a comment
and the thing (hw_id) to which the comment applies :(
So this patch reshuffles the comment and subject back together.
Also, as we're touching 'hw_id', let's change it from just 'unsigned'
to a fully-specified 'unsigned int', because some code checking tools
(including checkpatch) object to plain 'unsigned'.
