Pull drm updates from Dave Airlie:
"Here's the main drm pull request for 4.7, it's been a busy one, and
I've been a bit more distracted in real life this merge window. Lots
more ARM drivers, not sure if it'll ever end. I think I've at least
one more coming the next merge window.

commit 0a3e67a4caac273a3bfc4ced3da364830b1ab241
Author: Jesse Barnes <jbarnes@virtuousgeek.org>

drm: Rework vblank-wait handling to allow interrupt reduction.
to stay backwards-compatible with old UMS code that didn't even tell
the kernel when it did a modeset, so that the kernel could
save/restore vblank counters. At worst this means vblanks will be
somewhat funky on a setup that very likely no one still runs.
So let's just nuke it.
Plan B would be to set it unconditionally in drm_vblank_init for kms
drivers, instead of in each driver separately. So if this patch breaks
anything please only restore the hunks in drmP.h and drm_irq.c, plus
add a check for DRIVER_MODESET in drm_vblank_init.
Stumbled over this in a discussion on irc with Chris.

After drm_gem_object_lookup() was changed along with all its callers,
we have several drivers that have unused variables:

Switch the order of the loops to walk the rates on the top
so we exhaust all DP 1.1 rate/lane combinations before trying
DP 1.2 rate/lane combos.
This avoids selecting rates that are supported by the monitor,
but not the connector leading to valid modes getting rejected.

On DCE6.1 PPLL2 is exclusively available to UNIPHYA, so it should not
be taken into consideration when looking for an already enabled PLL
to be shared with other outputs.
This fixes the broken VGA port (TRAVIS DP->VGA bridge) on my Richland

a TRAVIS DP->LVDS bridge.

There is an issue observed when we hotplug a second DP
4K monitor to the system. Sometimes, the link training
fails for the second monitor after HPD interrupt
generation.
The issue happens when some queued or deferred transactions
are already present on the AUX channel when we initiate
a new transcation to (say) get DPCD or during link training.
We set AUX_IGNORE_HPD_DISCON bit in the AUX_CONTROL
register so that we can ignore any such deferred
transactions when a new AUX transaction is initiated.

When this flag is set, we program the hardware to execute the flip
during horizontal blank (i.e. for the next scanline) instead of during
vertical blank (i.e. for the next frame).
Currently this is only supported on ASICs which have a page flip
completion interrupt (>= R600), and only if the use_pflipirq parameter
has value 2 (the default).

rs600_hpd_init() and rs600_hpd_fini()
Silence UBSAN by checking ->hpd.hpd for RADEON_HPD_NONE before oring it
into the 'enabled' bitset in the *_init()- or the 'disabled' bitset in
the *_fini()-functions respectively.

Allowing userptr bo which are basicly a list of page from some vma
(so either anonymous page or file backed page) would lead to serious
corruption of kernel structures and counters (because we overwrite
the page->mapping field when mapping buffer).
This will already block if the buffer was populated before anyone does
try to mmap it because then TTM_PAGE_FLAG_SG would be set in in the
ttm_tt flags. But that flag is check before ttm_tt_populate in the ttm
vm fault handler.
So to be safe just add a check to verify_access() callback.

This reverts commit e64c952efb8e0c15ae82cec8e455ab4910690ef1.
ATPX is the ACPI method for controlling AMD PowerXpress laptops.
There are flags to indicate which methods are supported. If
the dGPU power down flag is not supported, the driver needs to
implement the dGPU power down manually. We had previously
always forced the driver to assume the ATPX dGPU power down
was present, but this causes problems on boards where it is
not, leading to GPU hangs when attempting to power down the
dGPU. Manual dGPU power down is not currently supported in
the Linux driver. Some laptops indicate that the ATPX
dGPU power down method is not present, but it actually
apparently is. I'm not sure if this is a bios bug and it should
be set or if there is a reason it was unset and the method should
not be used. This is not an issue on other OSes since both the
ATPX and the manual driver power down methods are supported.
This is apparently fairly widespread, so just revert for now.
