870d738acb drm/msm: subclass drm_atomic_state
This will give the kms backends a slot to stash their own hw specific
global state.

c056b55dc6 drm/msm/mdp5: introduce mdp5_hw_pipe
Split out the hardware pipe specifics from mdp5_plane.  To start, the hw
pipes are statically assigned to planes, but next step is to assign the
hw pipes during plane->atomic_check() based on requested caps (scaling,
YUV, etc).  And then hw pipe re-assignment if required if required SMP
blocks changes.

0002d30f3f drm/msm/mdp5: drop mdp5_plane::name
Just use plane->name now that it is a thing.  In a following patch, once
we dynamically assign hw pipes to planes, it won't make sense to name
planes the way we do, so this also partly reduces churn in following
patch.

d3937111cd drm/msm/mdp5: small rename
These are really plane-id's, not crtc-id's.  Only connection to CRTCs is
that they are used as primary-planes.

Current name is just legacy from when we only supported RGB/primary
planes.  Lets pick a better name now.

667ce33e57 drm/msm: support multiple address spaces
We can have various combinations of 64b and 32b address space, ie. 64b
CPU but 32b display and gpu, or 64b CPU and GPU but 32b display.  So
best to decouple the device iova's from mmap offset.

1455adbd45 drm/msm/mdp5: handle non-fullscreen base plane case
If the bottom-most layer is not fullscreen, we need to use the BASE
mixer stage for solid fill (ie. MDP5_CTL_BLEND_OP_FLAG_BORDER_OUT).  The
blend_setup() code pretty much handled this already, we just had to
figure this out in _atomic_check() and assign the stages appropriately.

Also fix the case where there are zero enabled planes, where we also
need to enable BORDER_OUT.

f54d186700 dma-buf: Rename struct fence to dma_fence
I plan to usurp the short name of struct fence for a core kernel struct,
and so I need to rename the specialised fence/timeline for DMA
operations to make room.

A consensus was reached in
https://lists.freedesktop.org/archives/dri-devel/2016-July/113083.html
that making clear this fence applies to DMA operations was a good thing.
Since then the patch has grown a bit as usage increases, so hopefully it
remains a good thing!

(v2...: rebase, rerun spatch)
v3: Compile on msm, spotted a manual fixup that I broke.
v4: Try again for msm, sorry Daniel

0853695c3b drm: Add reference counting to drm_atomic_state
drm_atomic_state has a complicated single owner model that tracks the
single reference from allocation through to destruction on another
thread - or perhaps on a local error path. We can simplify this tracking
by using reference counting (at a cost of a few more atomics). This is
even more beneficial when the lifetime of the state becomes more
convoluted than being passed to a single worker thread for the commit.

v2: Double check !intel atomic_commit functions for missing gets
v3: Update kerneldocs

f8049dd865 Merge branch 'msm-next' of git://people.freedesktop.org/~robclark/linux into drm-next
A bit smaller pull-req this time around.  Some continued DT binding
cleanup to get the corresponding dts bits merged upstream (through
other trees).  And explicit fence-fd support for submit ioctl.

* 'msm-next' of git://people.freedesktop.org/~robclark/linux:
  drm/msm: bump kernel api version for explicit fencing
  drm/msm: submit support for out-fences
  drm/msm: move fence allocation out of msm_gpu_submit()
  drm/msm: submit support for in-fences
  drm/msm: extend the submit ioctl to pass in flags
  drm/msm/mdp5: Set rotation property initial value to DRM_ROTATE_0 insted of 0
  drm/msm/hdmi: don't print error when adding i2c adapter fails

0f2886057b drm: Don't swallow error codes in drm_dev_alloc()
There are many reasons other than ENOMEM that drm_dev_init() can
fail. Return ERR_PTR rather than NULL to be able to distinguish
these in the caller.

d9c181e22a drm/msm: extend the submit ioctl to pass in flags
We'll want to be able to pass in flags, such as asking for explicit
fencing, and possibly other things down the road.  Fortunately we
don't need a full 32b for the pipe-id.  So use the upper 16 bits
for flags (which could be extended or reduced later if needed, so
start adding flags from the high bits).

Since anything with the upper bits set would not be a valid pipe-id,
an old userspace would not set any of the upper bits, and an old
kernel would reject it as an invalid pipe-id.

1d42a3fee6 drm/msm/mdp5: Set rotation property initial value to DRM_ROTATE_0 insted of 0
0 isn't a valid rotation property value, so let's set the initial value
of the property to DRM_ROTATE_0 instead.

In the same vein, we must always have at leat one angle as part of set
of supported rotation bits, so let's include DRM_ROTATE_0 in there.

14edbde1a6 drm/msm/mdp4: mark symbols static where possible
We get 2 warnings when building kernel with W=1:
drivers/gpu/drm/msm/mdp/mdp4/mdp4_lcdc_encoder.c:96:23: warning: no previous prototype for 'get_connector' [-Wmissing-prototypes]
drivers/gpu/drm/msm/mdp/mdp4/mdp4_plane.c:84:5: warning: no previous prototype for 'mdp4_plane_set_property' [-Wmissing-prototypes]

In fact, these functions are only used in the file in which they are
declared and don't need a declaration, but can be made static.
So this patch marks these functions with 'static'.

f755e227dc drm/msm: Remove call to reservation_object_test_signaled_rcu before wait
Since fence_wait_timeout_reservation_object_wait_timeout_rcu() with a
timeout of 0 becomes reservation_object_test_signaled_rcu(), we do not
need to handle such conversion in the caller. The only challenge are
those callers that wish to differentiate the error code between the
nonblocking busy check and potentially blocking wait.

v2: 9 is only 0 in German.

5f6f5e08b1 drm/msm/hdmi: Clean up HDMI gpio DT bindings
Make the following changes in the HDMI gpio bindings:

- Use "-gpios" as the suffix for all the gpio names
- Move all the gpios to optional, since there are platforms that use none
  of them.
- The HPD gpio is a standard one, remove the "qcom,hdmi-tx-" prefix from
  it.
- Remove the HDMI DDC clk/data gpios. They are just leftovers of an old
  way to configure pinctrl properties.
- Add a missing lpm gpio used on some platforms.

Make the necessary changes in the driver to incorporate these changes.

There hasn't been any upstream DT that uses the HDMI bindings, so it's
okay to change and move around these properties.

13ce5b6e38 drm/msm/mdp4: Fix issue with LCDC/LVDS port parsing
The LVDS port is the first in the list of the output ports in MDP4.
The driver assumed that if the port and its corresponding endpoint
is defined, then there should be a panel node too. This isn't
necessary since boards may not really use a LVDS panel. Don't fail
if there isn't a panel node available.

While we're at it, use of_graph_get_endpoint_by_regs instead of
of_graph_get_next_endpoint to make it more explicit that the LVDS
output is at port 0.

f6ce410a59 drm/fence: allow fence waiting to be interrupted by userspace
If userspace is running an synchronously atomic commit and interrupts the
atomic operation during fence_wait() it will hang until the timer expires,
so here we change the wait to be interruptible so it stop immediately when
userspace wants to quit.

Also adds the necessary error checking for fence_wait().

v2: Comment by Daniel Vetter
	- Add error checking for fence_wait()

v3: Rebase on top of new atomic noblocking support

v4: Comment by Maarten Lankhorst
	- remove 'swapped' bitfield as it was duplicating information

v5: Comments by Maarten Lankhorst
	- assign plane->state to plane_state if !intr

2b58e98d42 drm/atomic-helper: Add NO_DISABLE_AFTER_MODESET flag support for plane commit
Drivers may set the NO_DISABLE_AFTER_MODESET flag in the 'flags' parameter
of the helper drm_atomic_helper_commit_planes() if the relevant display
controllers(e.g., IPUv3 for imx-drm) require to disable a CRTC's planes
when the CRTC is disabled. The helper would skip the ->atomic_disable
call for a plane if the CRTC of the old plane state needs a modesetting
operation. Of course, the drivers need to disable the planes in their CRTC
disable callbacks since no one else would do that.
