Use drm_mode_get_hv_timing() to fill out the plane clip rectangle.
Note that this replaces crtc_state->adjusted_mode usage with
crtc_state->mode. The latter is the correct choice since that's the
mode the user provided and it matches the plane crtc coordinates
the user also provided.
Once everyone agrees on this we can move the clip handling into
drm_atomic_helper_check_plane_state().

drm_plane_helper_check_state()
drm_plane_helper_check_state() is supposed to do things the atomic way,
so it should not be inspecting crtc->enabled. Rather we should be
looking at crtc_state->enable.
We have a slight complication due to drm_plane_helper_check_update()
reusing drm_plane_helper_check_state() for non-atomic drivers. Thus
we'll have to pass the crtc_state in manally and construct a fake
crtc_state in drm_plane_helper_check_update().

When a plane moves out of bounds (i.e, outside the crtc clip region), the
plane state's "visible" parameter changes to false. When this happens, we
(a) release the hwpipe resources away from it, and
(b) unstage the corresponding hwpipe(s) from the Layer Mixers in the CRTC.
(a) requires use to acquire the global atomic state and assign a new
hwpipe. (b) requires us to re-configure the Layer Mixer, which is done in
the CRTC. We don't want to do these things in the async plane update path,
so return an error if the new state's "visible" isn't the same as the
current state's "visible".

MDP5 on newer SoCs support cursor planes (i.e, cursor SSPPs). They are a
separate entity unlike the cursors within LM.
Do not try to restore the MDP5 LM cursor registers, or the corresponding
CTL bits if we are not using LM cursors.
Also, since we've introduced a new variable 'lm_cursor_enabled', we can
now use it to avoid creating a different sets of crtc_funcs for CRTCs
with LM cursors and CRTCs with cursor planes.

We currently call mdp5_pipe_assign() twice to assign the left and right
hwpipes for our drm_plane. When merging 2 hwpipes, there are a few
constraints that we need to keep in mind:
- Only the same types of SSPPs are preferred. I.e, a RGB pipe should
be paired with another RGB pipe, VIG with VIG etc.
- The hwpipe staged on the left should have a higher priority than
the hwpipe staged on the right. The priorities are as follows:
VIG0 > VIG1 > VIG2 > VIG3
RGB0 > RGB1 > RGB2 > RGB3
DMA0 > DMA1
We can't apply these constraints easily if mdp5_pipe_assign() is
called twice. Update mdp5_pipe_assign() to find both hwpipes in
one go, and add the extra constraints needed.

Since we enabled runtime PM, we cannot count on cursor registers to
retain their values. This can result in situations where we think the
cursor is enabled when we enable the CRTC but it is trying to scan out
null (and the rest of cursor position/size is lost), resulting in faults
and generally angering the hw when coming out of DPMS with a cursor
enabled.

MDSS represents the top level wrapper that contains MDP5, DSI, HDMI and
other sub-blocks. W.r.t device heirarchy, it's the parent of all these
devices. The power domain of this device is actually tied to the GDSC
hw. When any sub-device enables its PD, MDSS's PD is also enabled.
The suspend/resume ops enable the top level clocks that end at the MDSS
boundary. For now, we're letting them all be optional, since the child
devices anyway hold a ref to these clocks.
Until now, we'd called a runtime_get() during probe, which ensured that
the GDSC was always on. Now that we've set up runtime PM for the children
devices, we can get rid of this hack.
Note: that the MDSS device is the platform_device in msm_drv.c. The
msm_runtime_suspend/resume ops call the funcs that enable/disable
the top level MDSS clocks. This is different from MDP4, where the
platform device created in msm_drv.c represents MDP4 itself. It would
have been nicer to hide these differences by adding new kms funcs, but
runtime PM needs to be enabled before kms is set up (i.e, msm_kms_init
is called).

Requests for assigning/freeing SMP blocks by planes are collected during
the atomic check phase, and represented by mdp5_smp_state's 'assigned'
and 'released' members.
Once the atomic state is committed, these members are reset to 0,
indicating that the existing configuration satisfies all the planes.
Future atomic commits will copy the old mdp5_smp_state, and the 'assigned'
and 'released' members would be updated only if there was a change in
the plane configurations.
When we disable and re-enable display, we lose the values we wrote to the
SMP registers, but the code doesn't program the registers because there
isn't any change in mdp5_smp_state.
Fix this by writing to the registers irrespective of whether there was
a change in SMP state or not. We do this by keeping a cache of the
register values, and write them every time we commit a state.

mdp5_enable/disable calls are scattered all around in the MDP5 code.
Use the pm_runtime_get/put calls here instead, and populate the
runtime PM suspend/resume ops to manage the clocks.
About the overall design: MDP5 is a child of the top level MDSS
device. MDSS is also the parent to DSI, HDMI and other interfaces. When
we enable MDP5's power domain, we end up enabling MDSS's PD too. It is
only MDSS's PD that actually controlls the GDSC HW. Therefore, calling
runtime_get/put on the MDP5 device is like just requesting a vote to
enable/disable the GDSC.
Functionally, replacing the clock enable/disable calls with the RPM API
can result in the power domain (GDSC) state being toggled if no other
child isn't powered on. This can result in the register context being lost.
We make sure (in future commits) that code paths don't end up configuring
registers and then later lose state, resulting in a bad HW state.
For now, we've replaced each mdp5_enable/disable with runtime_get/put API.
We could optimize things later by removing runtime_get/put calls which
don't really need to be there. This could prevent unnecessary toggling of
the power domain and clocks.

We have upstream bindings (msm8916) that have the "_clk" suffix in the

We want to drop the "_clk" suffix and at the same time support existing

This is the plumbing for supporting fb modifiers on planes. Modifiers
have already been introduced to some extent, but this series will extend
this to allow querying modifiers per plane. Based on this, the client to
enable optimal modifications for framebuffers.
This patch simply allows the DRM drivers to initialize their list of
supported modifiers upon initializing the plane.
v2: A minor addition from Daniel
v3:
* Updated commit message
* s/INVALID/DRM_FORMAT_MOD_INVALID (Liviu)
* Remove some excess newlines (Liviu)
* Update comment for > 64 modifiers (Liviu)
v4: Minor comment adjustments (Liviu)
v5: Some new platforms added due to rebase
v6: Add some missed plane inits (or maybe they're new - who knows at
this point) (Daniel)

for_each_obj_in_state is about to be removed, so convert
to the new iterator macros.
Just like in omap, use crtc_state->active instead of
crtc_state->enable when waiting for completion.
Changes since v1:
- Fix compilation.

The CRTC .disable() helper operation is deprecated for atomic drivers,
the new .atomic_disable() helper operation being preferred. Convert all
atomic drivers to .atomic_disable() to avoid cargo-cult use of
.disable() in new drivers.

The old state is useful for drivers that need to perform operations at
enable time that depend on the transition between the old and new
states.
While at it, rename the operation to .atomic_enable() to be consistent
with .atomic_disable(), as the .enable() operation is used by atomic
helpers only.

Buffer object specific resources like pages, domains, sg list
need not be protected with struct_mutex. They can be protected
with a buffer object level lock. This simplifies locking and
makes it easier to avoid potential recursive locking scenarios
for SVM involving mmap_sem and struct_mutex. This also removes
unnecessary serialization when creating buffer objects, and also
between buffer object creation and GPU command submission.

Now that the msm_gem supports an arbitrary number of vma's, we no longer
need to assign an id (index) to each address space. So rip out the
associated code.

No functional change, that will come later. But this will make it
easier to deal with dynamically created address spaces (ie. per-
process pagetables for gpu).

Before we can shift to passing the address-space object to _get_iova(),
we need to fix a few places (dsi+fbdev) that were hard-coding the adress
space id. That gets somewhat easier if we just move these to the kms
base class.
Prep work for next patch.
