Merge tag 'topic/drm-misc-2016-09-19' of git://anongit.freedesktop.org/drm-intel into drm-next

Just random misc stuff that Sean/Sumit&Archit picked up while I relaxed.
Well except for one commit:

* tag 'topic/drm-misc-2016-09-19' of git://anongit.freedesktop.org/drm-intel:
  drm: Only use compat ioctl for addfb2 on X86/IA64
  drm/qxl: squash lines for simple wrapper functions
  drm/bridge: analogix_dp: squash lines for simple wrapper functions
  drm/radeon: squash lines for simple wrapper functions
  drm/amdgpu: squash lines for simple wrapper functions
  dma-buf/sync-file: Avoid enable fence signaling if poll(.timeout=0)
  drm/fence: allow fence waiting to be interrupted by userspace
  drm: Move property validation to a helper, v2.
  drm/bridge: adv7511: add support for the 2nd chip

drm/ttm: remove cpu_address member from ttm_tt

Patch 3d50d4dcb0 exposed the CPU address of DMA-allocated pages as
returned by dma_alloc_coherent because Nouveau on Tegra needed it.

This is not required anymore - as there were no other users for it,
remove it and save some memory for everyone.

drm: Only use compat ioctl for addfb2 on X86/IA64

Similar to struct drm_update_draw, struct drm_mode_fb_cmd2 has an
unaligned 64 bit field (modifier). This get packed differently between
32 bit and 64 bit modes on architectures that can handle unaligned 64
bit access (X86 and IA64).  Other architectures pack the structs the
same and don't need the compat wrapper. Use the same condition for
drm_mode_fb_cmd2 as we use for drm_update_draw.

Note that only the modifier will be packed differently between compat
and non-compat versions.

drm/amdgpu: add missing header dependencies

We get a few warnings when building kernel with W=1:
drivers/gpu/drm/amd/amdgpu/amdgpu_pll.c:113:6: warning: no previous prototype for 'amdgpu_pll_compute' [-Wmissing-prototypes]
drivers/gpu/drm/amd/amdgpu/cz_smc.c:38:10: warning: no previous prototype for 'cz_get_argument' [-Wmissing-prototypes]
drivers/gpu/drm/amd/amdgpu/cz_smc.c:302:5: warning: no previous prototype for 'cz_smu_start' [-Wmissing-prototypes]
....

In fact, these functions are declared in
drivers/gpu/drm/amd/amdgpu/atombios_i2c.h
drivers/gpu/drm/amd/amdgpu/amdgpu_pll.h
drivers/gpu/drm/amd/amdgpu/cz_dpm.h
drivers/gpu/drm/amd/amdgpu/vi_dpm.h.
So this patch adds missing header dependencies.

drm: Move property validation to a helper, v2.

Property lifetimes are equal to the device lifetime, so the separate
drm_property_find is not needed. The pointer can be retrieved from
the properties member, which saves us some locking and a extra lookup.
The lifetime for properties is until the device is destroyed, which
happens late in the device unload path.

kms_atomic is also testing for invalid properties which returns -ENOENT,
to be consistent return -ENOENT for valid properties that don't appear
on the object property list.

Changes since v1:
- Return -ENOENT for invalid properties to make kms_atomic pass.
- Change commit message slightly to take this into account.

drm/sun4i: Add a DRC driver

The A33 pipeline also has a component called DRC. Even though its exact
features and programming model is not known (or documented), it needs to
be clocked for the pipeline to carry the video signal all the way.

Add a minimal driver for it that just claim the needed resources for the
pipeline to operate properly.
