When initially turning a crtc on, drm_reset_vblank_timestamp will
set the vblank timestamp to 0 for any driver that doesn't provide
a ->get_vblank_timestamp() hook.

Unfortunately, the FLIP_COMPLETE event depends on that timestamp,
and the only way to regenerate a valid one is to have vblank
interrupts enabled and have a valid in-ISR call to
drm_crtc_handle_vblank.

Additionally, if the user doesn't request vblanks but _does_ request
FLIP_COMPLETE events, we still don't have a good timestamp: it'll be the
same stamp as the last vblank one.

Work around the issue by always enabling vblanks when the CRTC is on.
Reducing the amount of time that PL0 has to be unmasked would be nice to
fix at a later time.

Changes since v1 [https://patchwork.freedesktop.org/patch/331727/]:
 - moved drm_crtc_vblank_put call to the ->atomic_disable() hook

Commit 554b3529 ("thermal/drivers/core: Remove the module Kconfig's
option") changed the type of THERMAL from tristate to bool, so
THERMAL || !THERMAL is now always y. Remove the redundant dependency.

Discovered through Kconfiglib detecting a dependency loop. The C tools
simplify the expression to y before running dependency loop detection,
and so don't see it. Changing the type of THERMAL back to tristate makes
the C tools detect the same loop.

Not sure if running dep. loop detection after simplification can be
called a bug. Fixing this nit unbreaks Kconfiglib on the kernel at
least.

This is a SW workaround for shadow un-flushed when together with the

D71 HW doesn't update shadow registers when display output is turned
off. So when we disable all pipeline components together with display
output disabling by one flush or one operation, the disable operation
updated registers will not be flushed or valid in HW, which may lead
problem. To workaround this problem, introduce a two phase disable for
pipeline disable.

Phase1: Disable components with display is on and flush it, this phase
        for flushing or validating the shadow registers.

Pinning lots of small buffer objects, such as cursors or sprites, to video

a small amount of memory. As a result, framebuffer images might not get

The flag DRM_GEM_VRAM_PL_FLAG_TOPDOWN marks buffer objects to be pinned at
the high end of video memory. This leaves contiguous space available at
the memory's low end.

The names for these functions are rather confusing. drm_dp_add_port()
sounds like a function that would simply create a port and add it to a
topology, and do nothing more. Similarly, drm_dp_update_port() would be
assumed to be the function that should be used to update port
information after initial creation.

While those assumptions are currently correct in how these functions are
used, a quick glance at drm_dp_add_port() reveals that drm_dp_add_port()
can also update the information on a port, and seems explicitly designed
to do so. This can be explained pretty simply by the fact that there's
more situations that would involve updating the port information based
on a link address response as opposed to a connection status
notification than the driver's initial topology probe. Case in point:
reprobing link addresses after suspend/resume.

Since we're about to start using drm_dp_add_port() differently for
suspend/resume reprobing, let's rename both functions to clarify what
they actually do.
