85dd1dd6e2 drm/vkms: Fix missing kmalloc allocation failure check 
Currently the kmalloc allocation for config is not being null
checked and could potentially lead to a null pointer dereference.
Fix this by adding the missing null check.

67f4aeb2b4 drm/sun4i: tcon: fix inverted DCLK polarity 
During commit 88bc417856 ("drm: Use new
DRM_BUS_FLAG_*_(DRIVE|SAMPLE)_(POS|NEG)EDGE flags") DRM_BUS_FLAG_*
macros have been changed to avoid ambiguity but just because of this
ambiguity previous DRM_BUS_FLAG_PIXDATA_(POS/NEG)EDGE were used meaning
_SAMPLE_ not _DRIVE_. This leads to DLCK inversion and need to fix but
instead of swapping phase values, let's adopt an easier approach Maxime
suggested:
It turned out that bit 26 of SUN4I_TCON0_IO_POL_REG is dedicated to
invert DCLK polarity and this makes things really easier than before. So
let's handle DCLK polarity by adding SUN4I_TCON0_IO_POL_DCLK_DRIVE_NEGEDGE
as bit 26 and activating according to bus_flags the same way it is done
for all the other signals polarity.

is disabled, and the DRM panel drivers are useless in that case, make the
omapfb2 panel depend on the standard DRM panels being disabled to fix
the name clash.

2df7af93fd drm/vkms: Add vkms_config type 
Currently, data for the device instance is held by vkms_device.
Add a separate type, vkms_config to contain configuration details
for the device and various modes to be later used by configfs.
This config data stays constant once the device is created.

Accordingly, add vkms_create and vkms_destroy to initialize/destroy
device through configfs. Currently, they are being called from vkms_init
and vkms_exit, but will be evoked from configfs later on. When configfs
is added, device configuration will be tracked by configfs and only vkms
device lifetime will be handled by vkms_init and vkms_exit functions.

Modify usage of enable_cursor feature to reflect the changes in
relevant files.

cc3283f8f4 drm/fourcc: fix Amlogic format modifier masks 
The comment says the layout and options use 8 bits, and the shift
uses 8 bits. However the mask is 0xf, ie. 0b00001111 (4 bits).

This could be surprising when introducing new layouts or options
that take more than 4 bits, as this would silently drop the high
bits.

Make the masks consistent with the comment and the shift.

Found when writing a drm_info patch [1].

dc25e3776e drm: distinguish return value of drm_dp_check_and_send_link_address 
drm_dp_check_and_send_link_address discovers MST device topology. It can
return both positive and negative values. When it returns positive
values there is no error found. If it returns negative values there is
error found, such as get NAK , timeout, etc. Following
drm_kms_helper_hotplug_event should be called when
drm_dp_check_and_send_link_address returns positive value.

1316b6e460 dt-bindings: display: Augment s6e63m0 bindings 
This fixes the following problems with the s6e63m0 display
bindings:

- When used on the DSI bus, the panel is listed directly as
  a subnode on the DSI host so the "port" node is not
  compulsory. Remove "port" from required properties.

- The panel contains its own backlight control, so reference
  the backlight common properties and list default-brightness
  and max-brightness as supported but optional properties.

b675542323 dt-bindings: display: Use OF graph schema 
Now that we have a graph schema, rework the display related schemas to use
it. Mostly this is adding a reference to graph.yaml and dropping duplicate
parts from schemas.

In panel-common.yaml, 'ports' is dropped. Any binding using 'ports'
should be one with more than 1 port node, and the binding must define
what each port is.

Note that ti,sn65dsi86.yaml, ti,tfp410,yaml and toshiba,tc358768.yaml will
need further updates to use video-interfaces.yaml once that lands.
