The Samsung ATNA33XC20 panel is an AMOLED eDP panel that has backlight

This panel is _almost_ able to be controlled in a "simple" way (and it
originally was implemented in panel-simple.c), but it's really
impossible to get the backlight semantics right there without adding
wacky special-case code to panel-simple. Let's give up and clone the
parts of panel-simple that we need and implement the power sequence

power-sequencing is non-standard the bindings are still "simple".

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.

drm: clean up unused kerneldoc in drm_lease.c
The kerneldoc in drm_lease.c is unused because none of the functions
are driver interfaces as the symbols are not exported.
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
held, but these are mostly redundant in cases where the function
contains lockdep assertions or grabs the mutex.
To simplify review, here's the reasoning behind each update.
drm_lease_owner:
function name is self-descriptive
_drm_find_lessee:
function name is self-descriptive
_drm_lease_held_master:
function name and signature are self-descriptive
_drm_has_leased:
kerneldoc is summarized into a comment because the function name could
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:
function name is self-descriptive
drm_lease_filter_crtcs:
Kerneldoc is summarized into a comment because the function name could
be interpreted ambiguously (filter leases based on crtcs mask VS
filter crtcs mask based on leases)
drm_lease_create:
Kerneldoc removed.
Useful function details such as atomic leasing are retained.
Errno interpretations are useful and retained.
drm_lease_destroy:
function name is self-descriptive. Additional information is also
removed as they're already present as comments inside the function.
_drm_lease_revoke:
function name is self-descriptive
drm_lease_revoke:
function name is self-descriptive
drm_mode_create_lease_ioctl:
Kerneldoc removed, but useful function details retained.
drm_mode_list_lessees_ioctl:
function name is self-descriptive. Additional details restate what the
code does.
drm_mode_get_lease_ioctl:
Function summary retained to clarify that it's the leased objects that
are returned, not the lease structure.

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

drm: rcar-du: lvds: Convert to DRM panel bridge helper
Replace the manual panel handling with usage of the DRM panel bridge
helper. This simplifies the driver, and brings support for
DRM_BRIDGE_ATTACH_NO_CONNECTOR as an added bonus.

drm: bridge: dw-hdmi: Attach to next bridge if available
On all platforms except i.MX and Rockchip, the dw-hdmi DT bindings
require a video output port connected to an HDMI sink (most likely an
HDMI connector, in rare cases another bridges converting HDMI to another
protocol). For those platforms, retrieve the next bridge and attach it
from the dw-hdmi bridge attach handler.

drm/bridge: Centralize error message when bridge attach fails
Being informed of a failure to attach a bridge is useful, and many
drivers prints an error message in that case. Move the message to
drm_bridge_attach() to avoid code duplication.

drm: rcar-du: Shutdown the display on remove
When the device is unbound from the driver (the DU being a platform
device, this occurs either when removing the DU module, or when
unbinding the device manually through sysfs), the display may be active.
Make sure it gets shut down.

The reference to the drm_device that was acquired by
devm_drm_dev_alloc() is released automatically by the devres

drm: rcar-du: Shutdown the display on system shutdown
When the system shuts down or warm reboots, the display may be active,
with the hardware accessing system memory. Upon reboot, the DDR will not
be accessible, which may cause issues.
Implement the platform_driver .shutdown() operation and shut down the
display to fix this.
