3c847d6cda drm/nouveau: Convert nouveau to use new iterator macros, v2.
Use the new atomic iterator macros, the old ones are about to be
removed. With the new macros, it's more easy to get old and new state so
get them from the macros instead of from obj->state.

Changes since v1:
- Don't mix up old and new state. (danvet)
- Rebase on top of interruptible swap_state changes.

34d8823738 drm/omapdrm: Fix omap_atomic_wait_for_completion
Use the new iterator macro and look for crtc_state->active instead of
enable, only crtc_state->active implies that vblanks will happen.

b20adb9188 drm/atomic: Use new iterator macros in drm_atomic_helper_wait_for_flip_done, again.
for_each_obj_in_state is about to be removed, so use the correct new
iterator macro.

I renamed the variable to 'unused', but forgot to convert
drm_atomic_helper_wait_for_flip_done to the new iterator macro,
so make it work this time.

eb5cb6aa9a drm/rockchip: vop: add a series of vop support
Vop Full framework now has following vops:
IP version    chipname
  3.1           rk3288
  3.2           rk3368
  3.4           rk3366

  3.7           rk3228
  3.8           rk3328

The above IP version is from H/W define, some of vop support get
the IP version from VERSION_INFO register, some are not.
hardcode the IP version for each vop to identify them.

major version: used for IP structure, Vop full framework is 3,
               vop little framework is 2.
minor version: on same structure, newer design vop will bigger
               then old one.

placing the line flags in the interrupt definition is

9548e1b49a drm/rockchip: vop: move write_relaxed flags to vop register
Since the drm atomic framework, only a small part of the vop
register needs sync write, Currently seems only following registers
need sync write:
   cfg_done, standby and interrupt related register.

All ctrl registers are using the sync write method that is
inefficient, hardcode the write_relaxed flags to vop registers,
then can only do synchronize write for those actual needed register.

At present we are using init_table to initialize some
registers, but the Register init table use un-document define,
it is unreadable, and sometimes we only want to update tiny
bits, init table method is not friendly, it's diffcult to
reuse for difference chips.

To make it clean, initialize registers directly, and drops

8312a3fe84 tinydrm: repaper: add CONFIG_THERMAL dependency
The new RePaper driver uses the thermal subsystem, and fails to link
when it is built-in but thermal is a loadable module:

drivers/gpu/drm/tinydrm/repaper.o: In function `repaper_probe':
repaper.c:(.text+0x540): undefined reference to `thermal_zone_get_zone_by_name'
drivers/gpu/drm/tinydrm/repaper.o: In function `repaper_fb_dirty':
repaper.c:(.text+0xff4): undefined reference to `thermal_zone_get_temp'

This adds another Kconfig dependency to prevent the broken configuration,
forcing repaper to be a module too.

4e6b1e9125 drm/vc4: Convert more lock requirement comments to lockdep assertions.
Since I do my development with lockdep on, this will help make sure I
don't introduce bugs here.

f30994622b drm/vc4: Add an ioctl for labeling GEM BOs for summary stats
This has proven immensely useful for debugging memory leaks and
overallocation (which is a rather serious concern on the platform,
given that we typically run at about 256MB of CMA out of up to 1GB
total memory, with framebuffers that are about 8MB ecah).

The state of the art without this is to dump debug logs from every GL
application, guess as to kernel allocations based on bo_stats, and try
to merge that all together into a global picture of memory allocation
state.  With this, you can add a couple of calls to the debug build of
the 3D driver and get a pretty detailed view of GPU memory usage from
/debug/dri/0/bo_stats (or when we debug print to dmesg on allocation
failure).

The Mesa side currently labels at the gallium resource level (so you
see that a 1920x20 pixmap has been created, presumably for the window
system panel), but we could extend that to be even more useful with
glObjectLabel() names being sent all the way down to the kernel.

(partial) example of sorted debugfs output with Mesa labeling all
resources:

               kernel BO cache:  16392kb BOs (3)
       tiling shadow 1920x1080:   8160kb BOs (1)
       resource 1920x1080@32/0:   8160kb BOs (1)
scanout resource 1920x1080@32/0:   8100kb BOs (1)
                        kernel:   8100kb BOs (1)

v2: Use strndup_user(), use lockdep assertion instead of just a
    comment, fix an array[-1] reference, extend comment about name
    freeing.

78acea381d Merge airlied/drm-next into drm-misc-next
Backmerge drm-next with -rc2 in it to pull in a couple stm patches that
were previously incorrectly applied to -misc-next. By picking them up in
the correct manner, git will hopefully fix any errant trees that are out
in the wild.

10ee275cb1 drm/vc4: prepare for CEC support
In order to support CEC the hsm clock needs to be enabled in
vc4_hdmi_bind(), not in vc4_hdmi_encoder_enable(). Otherwise you wouldn't
be able to support CEC when there is no hotplug detect signal, which is
required by some monitors that turn off the HPD when in standby, but keep
the CEC bus alive so they can be woken up.

The HDMI core also has to be enabled in vc4_hdmi_bind() for the same
reason.
