Based on commit 4cd0945901 ("drm/msm: submit support for out-fences").
We increment the minor driver version so userspace can detect explicit
fence support.

v3: Changed to work with fence returned from GPU submit.
I didn't spot anything that would require ordering here (well not
anywhere else either), and I'm trying to unify at least modern drivers
on one close hook.

It includes code cleanups from Bhumika and Liviu, a significant shader
performance fix and additions to the cmdstream validator from Wladimir
and the addition of a cmdbuf suballocator by myself.
The suballocator improves performance on all chips by reducing the CPU
overhead of the kernel driver and side steps the GC3000 FE MMU flush
erratum, now making the workarounds in IOVA allocation we had before
unnecessary, which results in a nice cleanup of the code in that area.

drm/etnaviv: Remove duplicate header file include
Revert "drm/etnaviv: trick drm_mm into giving out a low IOVA"

Don't allow IOMMUv2 to peek directly into the cmdbuf, but get the
needed PA through a dedicated function.

Including all drivers. I thought about keeping small compat functions
to avoid having to change all drivers. But I really like the
drm_printer idea, so figured spreading it more widely is a good thing.
v2: Review from Chris:
- Natural argument order and better name for drm_mm_print.
- show_mm() macro in the selftest.

drm_put_dev is the old midlayer-broken device cleanup function, but
etnaviv has a proper unbind function which first unregisters and then
drops the final reference. No functional change since
drm_dev_unregister happens to be idempotent.

It's deprecated and only should be used by drivers which still use
drm_platform_init, not by anyone else.
And indeed it's entirely unused and can be nuked.

Since commit 4984979b9b ("drm/irq: simplify irq checks in
drm_wait_vblank"), the drm driver feature flag DRIVER_HAVE_IRQ is only
required for drivers that have an IRQ handler managed by the DRM core.
Some drivers, armada, etnaviv, kirin and sti, set this flag without
.irq_handler setup in drm_driver. These drivers manage IRQ handler
by themselves and the flag DRIVER_HAVE_IRQ makes no sense there.
Drop the flag for these drivers to avoid confusion.

etnaviv-next only contains two patches to get rid of a confusing error
message and finally one patch to enable the autonomous GPU clock gating.
* 'drm-etnaviv-next' of git://git.pengutronix.de/git/lst/linux:
drm/etnaviv: remove generic GPU init failure reporting
drm/etnaviv: improve error reporting in GPU init path
drm/etnaviv: enable GPU module level clock gating support
The GPU init path now reports any errors which might occur more accurately
than what is possible with the generic "something failed" message.
Remove the generic reporting, so we don't log an error into dmesg anymore
if any of the GPU cores are ignored.

We already have a fallback in place to fill out the unique from
dev->unique, which is set to something reasonable in drm_dev_alloc.
Which means we only need to have a special set_busid for pci devices,
to be able to care the backwards compat code for drm 1.1 around, which
libdrm still needs.
While developing and testing this patch things blew up in really
interesting ways, and the code is rather confusing in naming things
between the kernel code, ioctl #defines and libdrm. For the next brave
dragon slayer, document all this madness properly in the userspace
interface section of gpu.tmpl.
v2: Make drm_dev_set_unique static and update kerneldoc.
v3: Entire rewrite, plus document what's going on for posterity in the
gpu docbook uapi section.
v4: Drop accidental amdgpu hunk (Emil).
v5: Drop accidental omapdrm vblank counter change (Emil).
v6: Rebase on top of the sphinx conversion.
