Subject: drm/panel: Add driver for Samsung S6E63M0 panel
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch adds Samsung S6E63M0 AMOLED LCD panel driver, connected over
spi. It's based on already removed, non-device-tree S6E63M0 driver and
panel-samsung-ld9040. It can be found for example in some of Samsung
Aries based phones.

Subject: drm/panel: Add OSD101T2587-53TS driver

The panel is similar to OSD101T2045-53TS (which is handled by panel-simple)
with one big difference: osd101t2587-53ts needs MIPI_DSI_TURN_ON_PERIPHERAL
message to be sent from the host to be operational and thus can not be
handled by panel-simple.

Drop use of the deprecated drmP.h header file.

While touching the list of include files:
- Divide include files in blocks of linux/* video/* drm/* etc.
  Be consistent in the order of the blocks
- Sort individual blocks of include files

Subject: drm/panel: truly: Add additional delay after pulling down reset gpio

MTP SDM845 panel seems to need additional delay to bring panel
to a workable state. Running modetest without this change displays
blurry artifacts.

Subject: panel: rocktech: no need to check return value of debugfs_create
 functions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When calling debugfs functions, there is no need to ever check the
return value.  The function can work or not, but the code logic should
never do something different based on this.
