DRM is a lot more than a direct rendering manager nowadays, and there's
also a bunch of things worth documenting for gpu driver developers
outside of drivers/gpu/drm, like vgaarb, vga_switcheroo or the various
hardware buses like host1x and ipu-v3.
To avoid further confusion let's rename the top-level to reflect
reality.
And yes I'm already looking forward to when we need to replace the G
in GPU with a * ;-)
Inspired by a thread with Lukas since he refused to include the
vga_switcheroo docs into the drm docs because it's not drm.

Add a new debug class for _verbose_ debug message from the vblank code.
That is message we spew out potentially for every vblank interrupt.
Thierry already got annoyed at the spew, and now I managed to lock up
my box with these debug prints (seems serial console + a few debug
prints every vblank aren't a good combination).
Or should I maybe call it DRM_DEBUG_IRQ?

Just one special case (since i915 lost its ums code, yay):
- radeon: Has slots for the old ums ioctls which don't have
DRM_UNLOCKED, but all filled with drm_invalid_op. So ok to drop it
everywhere.
Every other kms driver just has DRM_UNLOCKED for all their ioctls, as
they should.
v2: admgpu happened, include that one too. And i915 lost its UMS
support which means we can change all the i915 ioctls too.
v3: Rebased on top of new vmwgfx DX interface extensions.
v4: Rebase on top of render-node support in exynos.

With the prep patches for i915 all kms drivers either have
DRM_UNLOCKED on all their ioctls. Or the ioctl always directly returns
with an invariant return value when in modeset mode. But that's only
the case for i915 and radeon. The drm core ioctls are unfortunately
too much a mess still to dare this.
Follow-up patches will remove DRM_UNLOCKED from all kms drivers to
prove that this is indeed the case.
Also update the documentation.
v2: Really only do this for driver ioctls, spotted by David Herrmann.

With kms all the data getparam looks at is actually invariant, and
certainly not protected by the global kms mutex. With ums all the
setup code is already racy as hell, so this won't make things any
worse.
I've done this change so that all ioctl still used by kms drivers
are marked as DRM_UNLOCKED, besides that we obviously don't need
it any more in kms mode.

This series:
* adds support for interlaced video modes to the ipu-v3 driver
and dw_hdmi bridge.
* reworks the dw_hdmi connector enable/disable support, to ensure that
when DRM disables the output, it stays disabled irrespective of the
hotplug state.
* adds support for connector forcing, so we can force the hotplug state
for this connector.
* adds the ALSA AHB audio driver to the bridge: Iwai has acked the
audio driver.
* a few fixes to the ACR calculations to allow more modes to work with
audio on iMX6.
Fabio has independently tested this series, so all patches here carry
his tested-by tag.
