It would race between userspace thread and commit worker. Ie. vblank
irq would trigger event and userspace could begin the next atomic
update, before the commit worker had a chance to clear the pending
flag.
If we do end up needing something to prevent userspace from trying
another pageflip before getting vblank event, it should probably be
implemented as a pending_planes bitmask, similar to pending_crtcs. See
start_atomic() and end_atomic().

Replace uses of fb->pixel_format with fb->format->format.
Less duplicated information is a good thing.
Note that coccinelle failed to eliminate the
"/* fourcc format */" comment from drm_framebuffer.h, so I had
to do that part manually.

drm-next
On the userspace side, all the basics are working, and most of glmark2
is working. I've been working through deqp, and I've got a couple more
things to fix (but we've gone from 70% to 80+% pass in last day, and
current deqp run that is going should pick up another 5-10%). I expect
to push the mesa patches today or tomorrow.
There are a couple more a5xx related patches to take the gpu out of
secure mode (for the devices that come up in secure mode, like the hw
I have), but those depend on an scm patch that would come in through
another tree. If that can land in the next day or two, there might
be a second late pull request for drm/msm.
In addition to the new-shiny, there have also been a lot of overlay/
plane related fixes for issues found using drm-hwc2 (in the process of
testing/debugging the atomic/kms fence patches), resulting in rework
to assign hwpipes to kms planes dynamically (as part of global atomic
state) and also handling SMP (fifo) block allocation atomically as
part of the ->atomic_check() step. All those patches should also help
out atomic weston (when those patches eventually land).

For a5xx the gpu is 64b so we need to change iova to 64b everywhere. On
the display side, iova is still 32b so it can ignore the upper bits.
(Although all the armv8 devices have an iommu that can map 64b pa to 32b
iova.)

The mode_config->max_{width,height} is for the maximum size of a fb, not
the max scanout limits (of the layer-mixer). It is legal, and in fact
common, to create a larger fb, only only scan-out a smaller part of it.
For example multi-monitor configurations for x11, or android wallpaper
layer (which is created larger than the screen resolution for fast
scrolling by just changing the src x/y coordinates).

Previously, SMP block allocation was not checked in the plane's
atomic_check() fxn, so we could fail allocation SMP block allocation at
atomic_update() time. Re-work the block allocation to request blocks
during atomic_check(), but not update the hw until committing the atomic
update.
Since SMP blocks allocated at atomic_check() time, we need to manage the
SMP state as part of mdp5_state (global atomic state). This actually
ends up significantly simplifying the SMP management, as the SMP module
does not need to manage the intermediate state between assigning new
blocks before setting flush bits and releasing old blocks after vblank.
(The SMP registers and SMP allocation is not double-buffered, so newly
allocated blocks need to be updated in kms->prepare_commit() released
blocks in kms->complete_commit().)

(re)assign the hw pipes to planes based on required caps, and to handle
situations where we could not modify an in-use plane (ie. SMP block
reallocation).
This means all planes advertise the superset of formats and properties.
Userspace must (as always) use atomic TEST_ONLY step for atomic updates,
as not all planes may be available for use on every frame.
The mapping of hwpipe to plane is stored in mdp5_state, so that state
updates are atomically committed in the same way that plane/etc state
updates are managed. This is needed because the mdp5_plane_state keeps
a pointer to the hwpipe, and we don't want global state to become out
of sync with the plane state if an atomic update fails, we hit deadlock/
backoff scenario, etc. The use of state_lock keeps multiple parallel
updates which both re-assign hwpipes properly serialized.

Add basic state duplication/apply mechanism. Following commits will
move actual global hw state into this.
The state_lock allows multiple concurrent updates to proceed as long as
they don't both try to alter global state. The ww_mutex mechanism will
trigger backoff in case of deadlock between multiple threads trying to
update state.

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.

We can have various combinations of 64b and 32b address space, ie. 64b

It has been suggested that having per-plane modifiers is making life
more difficult for userspace, so let's just retire modifier[1-3] and
use modifier[0] to apply to the entire framebuffer.
Obviosuly this means that if individual planes need different tiling
layouts and whatnot we will need a new modifier for each combination
of planes with different tiling layouts.
For a bit of extra backwards compatilbilty the kernel will allow
non-zero modifier[1+] but it require that they will match modifier[0].
This in case there's existing userspace out there that sets
modifier[1+] to something non-zero with planar formats.
Mostly a cocci job, with a bit of manual stuff mixed in.

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.

Previously, the "qcom,mdp5" and "qcom,mdss_mdp" compatible strings
were used to match the top level platform_device (which was also tied

With the new device hierarchy for MDP5, we need to enable runtime PM
for both the toplevel MDSS device and the MDP5 device itself. Enable
runtime PM for the new devices.
Since MDP4 and MDP5 now have different places where runtime PM is
enabled, remove the previous pm_runtime_enable/disable calls, and
squash them in the respective kms drivers.
The new device hierarchy (as expressed in the DT bindings) has the GDSC
tied only to the MDSS wrapper device. This GDSC needs to be enabled for
accessing any register in the MDSS sub-blocks. Once every driver is
runtime adapted, the GDSC will be enabled when any sub-block device
calls runtime_get because of the parent-child relationship with MDSS.
Until then, we call pm_runtime_get_sync() once for the MDSS device to
ensure the GDSC is never disabled. This will be removed once all the
drivers are runtime PM adapted.
The error handling paths become a bit tricky when we call these runtime
PM funcs. There doesn't seem to be any helper that checks if runtime PM
is enabled already. Add bool variables in mdp4_kms/mdp5_kms structs to
check if the driver had managed to call pm_runtime_enable before bailing
out.

The MDP5 sub-block register offsets are relative to the top level
MDSS register address.
Now that we have the start of MDP5 register address space, provide
the offsets relative to that. This involves subtracting the offsets
with 0x1000 or 0x100 depending on the MDP5 version.

Since MDSS registers were stuffed within the the MDP5 register
space, we had an __offset_MDP() macro to identify the offset
between the start of MDSS and MDP5 address spaces. This offset
macro expected a MDP index argument, which didn't make much
sense since we don't have multiple MDPs.
The offset is no longer needed now that we have devices for the 2
different register address spaces. Also, remove the "REG_MDP5_MDP_"
prefix to "REG_MDP5_".
Update the generated headers in mdp5.xml.h
We generally update headers as a separate patch, but we need to
do these together to prevent breaking build.

With the new kms_init/destroy funcs in place for MDP5, we can get rid of
the old kms funcs. Some members of the mdp5_kms struct also become
redundant, so we remove those too.

Call msm_mdss_init in msm_drv to set up top level registers/irq line.
Start using the new kms_init2/destroy2 funcs to inititalize MDP5 KMS.
With the MDSS interrupt and irqdomain set up, the old MDP5 irq code
can be dropped.
The mdp5_hw_init kms func now uses the platform device tied to MDP5
instead of the one tied to the drm_device/MDSS.

With MDP5 as a new device, we need to do less for MDP when initializing
modeset after all the components are bound.
Create mdp5_kms_init2/destroy2 funcs that inits modeset. These will
eventually replace the older kms_init/destroy funcs.
In the new kms_init2, the platform_device used is the one corresponding
to the new MDP5 platform_device. The new change here is that the irq is
now retrieved using irq_of_parse_and_map(), since MDP5 is a child interrupt
of the MDSS interrupt controller.
