The DPU has some kind of idea that it wants to be able to
bring up power using GPIO lines. The struct dss_gpio is however
completely unused and should this be done, it should be done
using the GPIO descriptor framework rather than this API
which relies on the global GPIO numberspace. Delete this
code before anyone hurt themselves.
The inclusion of <linux/gpio.h> was abused to get some OF
and IRQ headers implicitly included into the DPU utilities,
make these includes explicit and push them down into the actual
implementation.

Drop the deprecated drmP.h header file, and trim msm_drv.h
to the relevant include files.
This resulted in a suprisingly many edits as many files relied
on headers included via msm_drv.h.
But msm_drv.h is not supposed to carry include files it do not need, so
the individual files have to include what extra they needs.

The mdp5 drm/kms driver currently does not work on command-mode DSI
panels due to 'vblank wait timed out' errors. This causes a latency
of seconds, or tens of seconds in some cases, before content is shown
on the panel. This hardware does not have the something that we can use
as a frame counter available when running in command mode, so we need to
fall back to using timestamps by setting the max_vblank_count to zero.
This can be done on a per-CRTC basis, so the convert mdp5 to use
drm_crtc_set_max_vblank_count().
This change was tested on a LG Nexus 5 (hammerhead) phone.

To make the voting balanced add a minimum vote in

The interconnect framework is designed to provide a
standard kernel interface to control the settings of
the interconnects on a SoC.
The interconnect API uses a consumer/provider-based model,
where the providers are the interconnect buses and the
consumers could be various drivers.
MDSS is one of the interconnect consumers which uses the
interconnect APIs to get the path between endpoints and
set its bandwidth requirement for the given interconnected
path.
Changes in v2:
- Remove error log and unnecessary check (Jordan Crouse)
Changes in v3:
- Code clean involving variable name change, removal
of extra paranthesis and variables (Matthias Kaehlcke)
Changes in v4:
- Add comments, spacings, tabs, proper port name

Changes in v5:
- Commit text and parenthesis alignment (Georgi Djakov)
Changes in v6:
- Change to new icc_set API's (Doug Anderson)
Changes in v7:
- Fixed a typo
Changes in v8:
- Handle the of_icc_get() returning NULL case. In practice
icc_set_bw() will gracefully handle the case of a NULL path,
but it's probably best for clarity to keep num_paths=0 in
this case.

So far, the drm_format_plane_cpp function was operating on the format's
fourcc and was doing a lookup to retrieve the drm_format_info structure and
return the cpp.
However, this is inefficient since in most cases, we will have the
drm_format_info pointer already available so we shouldn't have to perform a
new lookup. Some drm_fourcc functions also already operate on the
drm_format_info pointer for that reason, so the API is quite inconsistent
there.
Let's follow the latter pattern and remove the extra lookup while being a
bit more consistent. In order to be extra consistent, also rename that
function to drm_format_info_plane_cpp and to a static function in the
header to match the current policy.

drm_format_horz_chroma_subsampling and drm_format_vert_chroma_subsampling
are basically a lookup in the drm_format_info table plus an access to the
hsub and vsub fields of the appropriate entry.
Most drivers are using this function while having access to the entry
already, which means that we will perform an unnecessary lookup. Removing
the call to these functions is therefore more efficient.
Some drivers will not have access to that entry in the function, but in
this case the overhead is minimal (we just have to call drm_format_info()
to perform the lookup) and we can even avoid multiple, inefficient lookups
in some places that need multiple fields from the drm_format_info
structure.
This is amplified by the fact that most of the time the callers will have
to retrieve both the vsub and hsub fields, meaning that they would perform
twice the lookup.

The msm_gem_object structure contains resv and _resv fields that are
no longer needed since the reservation object is now stored on
drm_gem_object. msm_atomic_prepare_fb() and msm_atomic_prepare_fb()
both referenced the wrong reservation object, and would lead to an
attempt to dereference a NULL pointer. Correct those two cases to
point to the correct reservation object.

The frame_busy mask is used in frame_done event handling, which is not
invoked for async commits. So an async commit will leave the
frame_busy mask populated after it completes and future commits will start
with the busy mask incorrect.
This showed up on disable after cursor move. I was hitting the "this should
not happen" comment in the frame event worker since frame_busy was set,
we queued the event, but there were no frames pending (since async
also doesn't set that).

In the case of an async/cursor update, we don't wait for the frame_done
event, which means handle_frame_done is never called, and the frame_done
watchdog isn't canceled. Currently, this results in a frame_done timeout
every time the cursor moves without a synchronous frame following it up
before the timeout expires. Since we don't wait for frame_done, and
don't handle it, we shouldn't modify the watchdog.

There exists a bunch of confusion as to what the actual units of
frame_done is:
- The definition states it's in # of frames
- CRTC treats it like it's ms
- frame_done_timeout comment thinks it's Hz, but it stores ms
- frame_done timer is setup such that it _should_ be in frames, but the
timeout is super long
So this patch tries to interpret what the driver really wants. I've
de-centralized the #define since the consumers are expecting different
units.
For crtc, we just use 60ms since that's what it was doing before.
Perhaps we could get fancy and scale with vrefresh, but that's for
another time.
For encoder, fix the comments and rename frame_done_timeout so it's
obvious what the units are. In practice, frame_done_timeout is really
just checked against 0 || !0, which I guess is why the units being wrong
didn't matter. I've also dropped the timeout from the previous 60 frames
to 5. That seems like more than enough time to give up on a frame, and
my guess is that no one intended for the timeout to _actually_ be 60
frames.
