Those delays were added to support the Samsung ATNA33XC20
panel. However, we've moving that to its own panel driver and out of
panel-simple. That means we don't need the ability to specify this
delay.
NOTE: it's unlikely we want to keep this delay "just in case" some
other panel needs it. The enable-gpio and the power supply are really
supposed to be different ways to specify the same thing: the main
enable of the panel. Supporting a delay between them doesn't really

drm/bridge: ti-sn65dsi86: Fix power off sequence
When testing with a panel that's apparently a little more persnickety
about the correct power sequence (specifically Samsung ATNA33XC20), we
found that the ti-sn65dsi86 was doing things just slightly wrong.
Looking closely at the ti-sn65dsi86's datasheet, the power off
sequence is supposed to be:
1. Clear VSTREAM_ENABLE bit
2. Stop DSI stream from GPU. DSI lanes must be placed in LP11 state.
3. Program the ML_TX_MODE to 0x0 (OFF)
4. Program the DP_NUM_LANES register to 0x0
5. Clear the DP_PLL_EN bit.
6. Deassert the EN pin.
7. Remove power from supply pins
Since we were doing the whole sequence in the "disable", I believe
that step #2 (stopping the DSI stream from the GPU) wasn't
happening. We also weren't setting DP_NUM_LANES to 0.
Let's fix this.
NOTE: things are a little asymmetric now. For instance, we turn the
PLL on in "enable" but now we're not turning it off until
"post_disable". It would seem to make sense to move the PLL turning on
to "pre_enable" to match. Unfortunately, I don't believe that's
allowed. It looks as if (in the non-refclk mode which probably nobody
is using) we have to wait until the MIPI clock is there before we can
enable the PLL. In any case, the way it is here won't really
hurt--it'll just leave the PLL on a little longer.

Since they aren't used and much of the existing comments don't provide
any insights (e.g. they just repeat the function name or list out the
function parameters), they should be removed to make them easier to
maintain and to make useful info more obvious.
As a note, many of the comments mention whether idr_mutex should be

To simplify review, here's the reasoning behind each update.

function name is self-descriptive
_drm_lease_held_master:
function name and signature are self-descriptive
_drm_has_leased:

be interpreted ambiguously (check if the object has been leased VS
check if the master has a lease on the object)
_drm_lease_held:
Retain the idr_mutex comment because the function does not directly
grab the mutex or use a lockdep assertion.
Otherwise, the function name is self-descriptive.
drm_lease_held:

_drm_lease_revoke:

drm_mode_create_lease_ioctl:

drm_mode_list_lessees_ioctl:

drm/vmwgfx: Be a lot more flexible with MOB limits
The code was trying to keep a strict limit on the amount of mob
memory that was used in the guest by making it match the host
settings. There's technically no reason to do that (guests can
certainly use more than the host can have resident in renderers
at the same time).
In particular this is problematic because our userspace is not
great at handling OOM conditions and running out of MOB space
results in GL apps crashing, e.g. gnome-shell likes to allocate
huge surfaces (~61MB for the desktop on 2560x1600 with two workspaces)
and running out of memory there means that the gnome-shell crashes
on startup taking us back to the login and resulting in a system
where one can not login in graphically anymore.
Instead of letting the userspace crash we can extend available
MOB space, we just don't want to use all of the RAM for graphics,
so we're going to limit it to half of RAM.
With the addition of some extra logging this should make the
"guest has been configured with not enough graphics memory"
errors a lot easier to diagnose in cases where the automatic
expansion of MOB space fails.

our logging a bit and clean it up in the process.
vmwgfx is a little special because technically the hardware it's
running on can be anything from the last 12 years or so which is

drm/vmwgfx: Switch to using DRM_IOCTL_DEF_DRV
The macro has been accounting for DRM_COMMAND_BASE for a long time
now so there's no reason to still be duplicating it. Plus we were
leaving the name undefined which meant that all the DRM ioctl
warnings/errors were always listing "null" ioctl at the culprit.
This fixes the undefined ioctl name and removes duplicated code.

drm/msm/gem: Mark active before pinning
Mark all the bos in the submit as active, before pinning, to prevent
evicting a buffer in the same submit to make room for a buffer earlier
in the table.

drm/msm: Utilize gpu scheduler priorities
The drm/scheduler provides additional prioritization on top of that
provided by however many number of ringbuffers (each with their own
priority level) is supported on a given generation. Expose the
additional levels of priority to userspace and map the userspace
priority back to ring (first level of priority) and schedular priority
(additional priority levels within the ring).

It is sufficient to serialize on the submit queue now.

drm/msm: Drop submit bo_list
This was only used to detect userspace including the same bo multiple
times in a submit. But ww_mutex can already tell us this.
When we drop struct_mutex around the submit ioctl, we'd otherwise need
to lock the bo before adding it to the bo_list. But since ww_mutex can
already tell us this, it is simpler just to remove the bo_list.

drm/msm: Conversion to drm scheduler
For existing adrenos, there is one or more ringbuffer, depending on
whether preemption is supported. When preemption is supported, each
ringbuffer has it's own priority. A submitqueue (which maps to a
gl context or vk queue in userspace) is mapped to a specific ring-
buffer at creation time, based on the submitqueue's priority.
Each ringbuffer has it's own drm_gpu_scheduler. Each submitqueue
maps to a drm_sched_entity. And each submit maps to a drm_sched_job.
