Call the driver first and have it call the common code cleanup.
This is useful later to fix unbind.

This moves the generic tracking into the drivers and protects
against reentrancy in the drivers. It fixes up radeon and agp
to be able to query the bound status as that is required.

GPU drivers need this in their shrinkers, to be able to throw out
mmap'ed buffers. Note that we also need dma_resv_lock in shrinkers,
but that loop is resolved by trylocking in shrinkers.
So full hierarchy is now (ignore some of the other branches we already
have primed):
mmap_read_lock -> dma_resv -> shrinkers -> i_mmap_lock_write
I hope that's not inconsistent with anything mm or fs does, adding
relevant people.

This change simplifies ast's modesetting code. The display mode
is now programmed from within the CRTC's atomic_enable(), which
only runs if we actually want to program the mode.
Corresponding code in atomic_flush() is being removed. Also removed
is atomic_begin(), which serves no purpose at all.

The ast HW cursor requires the primary plane and CRTC to display at
a valid mode and format. This is not the case while switching
display modes, which can lead to the screen turing permanently dark.
As a workaround, the ast driver now disables active planes while the
mode or format switch takes place. It also synchronizes with the vertical
refresh to give CRTC and planes some time to catch up on each other.
The active planes planes (primary or cursor) will be re-enabled by
each plane's atomic_update() function.

* move the logic into the CRTC's atomic_disable function

The atomic modesetting code tried to distinguish format changes from
full modesetting operations. But the implementation was buggy and the
format registers were often updated even for simple pageflips.
Fix this problem by handling format changes in the primary plane's
update function.

The lcdif IP does not support a framebuffer pitch (stride) other than
framebuffer width. Check for equality and reject the framebuffer
otherwise.
This prevents a distorted picture when using 640x800 and running the
Mesa graphics stack. Mesa tries to use a cache aligned stride, which
leads at that particular resolution to width != stride. Currently
Mesa has no fallback behavior, but rejecting this configuration allows
userspace to handle the issue correctly.

The get_edid() callback can be triggered anytime by an ioctl, i.e
drm_mode_getconnector (ioctl)
-> drm_helper_probe_single_connector_modes
-> drm_bridge_connector_get_modes
-> ps8640_bridge_get_edid
Actually if the bridge pre_enable() function was not called before
get_edid(), the driver will not be able to get the EDID properly and
display will not work until a second get_edid() call is issued and if
pre_enable() is called before. The side effect of this, for example, is
that you see anything when `Frecon` starts, neither the splash screen,
until the graphical session manager starts.
To fix this we need to make sure that all we need is enabled before
reading the EDID. This means the following:
1. If get_edid() is called before having the device powered we need to
power on the device. In such case, the driver will power off again the
device.
2. If get_edid() is called after having the device powered, all should
just work. We added a powered flag in order to avoid recurrent calls
to ps8640_bridge_poweron() and unneeded delays.
3. This seems to be specific for this device, but we need to make sure
the panel is powered on before do a power on cycle on this device.
Otherwise the device fails to retrieve the EDID.

Ingenic SoCs are most notably used in cheap chinese handheld gaming
consoles. There, the games and applications generally render in software
directly into GEM buffers.
Traditionally, GEM buffers are mapped write-combine. Writes to the
buffer are accelerated, and reads are slow. Application doing lots of
alpha-blending paint inside shadow buffers, which is then memcpy'd into
the final GEM buffer.
On recent Ingenic SoCs however, it is much faster to have a fully cached
GEM buffer, in which applications paint directly, and whose data is
invalidated before scanout, than having a write-combine GEM buffer, even
when alpha blending is not used.
Add an optional 'cached_gem_buffers' parameter to the ingenic-drm driver
to allow GEM buffers to be mapped fully-cached, in order to speed up
software rendering.
v2: Use standard noncoherent DMA APIs
v3: Use damage clips instead of invalidating full frames
v4: Avoid dma_pgprot() which is not exported. Using vm_get_page_prot()
is enough in this case.
v5:
- Avoid calling drm_gem_cma_prime_mmap(). It has the side effect that an
extra object reference is obtained, which causes our dumb buffers to
never be freed. It should have been drm_gem_cma_mmap_obj(). However,
our custom mmap function only differs with one flag, so we can cleanly
handle both modes in ingenic_drm_gem_mmap().
- Call drm_gem_vm_close() if drm_mmap_attrs() failed, just like in
drm_gem_cma_mmap_obj().

We update the timestamping constants per-crtc explicitly in
intel_crtc_update_active_timings(). Furtermore the helper will
use uapi.adjusted_mode whereas we want hw.adjusted_mode. Thus
let's drop the helper call an rely on what we already have in
intel_crtc_update_active_timings(). We can now also drop the
hw.adjusted_mode -> uapi.adjusted_mode copy hack that was added
to keep the helper from deriving the timestamping constants from

So it never made sense to make this a flag in the first place.
Nuke the flags and specify directly which memory type to use.
