The Anbernic RG353V-V2 is a 5 inch panel used in a new revision of the
Anbernic RG353V handheld gaming device. Add support for it.
Unfortunately it appears this controller is not able to support 120hz
or 100hz mode like the first revision panel.

This chip supports controlling the backlight via DCS commands, on at

Note this may only concern the NT36523*W* variant. Nobody knows, really,

Add support for the Sony TD4353 JDI 2160x1080 display panel used in
some Sony Xperia XZ2 and XZ2 Compact smartphones. Due to the specifics
of smartphone manufacturing, it is impossible to retrieve a better name
for this panel.
This revision adds support for the default 60 Hz configuration, however
there could possibly be some room for expansion, as the display panels
used on Sony devices have historically been capable of >2x refresh rate
overclocking.

The unprepare sequence has started to fail after moving to panel bridge
code in the msm drm driver (commit 007ac0262b0d ("drm/msm/dsi: switch to
DRM_PANEL_BRIDGE")). You'll see messages like this in the kernel logs:
panel-boe-tv101wum-nl6 ae94000.dsi.0: failed to set panel off: -22
This is because boe_panel_enter_sleep_mode() needs an operating DSI link
to set the panel into sleep mode. Performing those writes in the
unprepare phase of bridge ops is too late, because the link has already
been torn down by the DSI controller in post_disable, i.e. the PHY has
been disabled, etc. See dsi_mgr_bridge_post_disable() for more details
on the DSI .
Split the unprepare function into a disable part and an unprepare part.
For now, just the DSI writes to enter sleep mode are put in the disable
function. This fixes the panel off routine and keeps the panel happy.
My Wormdingler has an integrated touchscreen that stops responding to
touch if the panel is only half disabled too. This patch fixes it. And
finally, this saves power when the screen is off because without this
fix the regulators for the panel are left enabled when nothing is being
displayed on the screen.

Enable the drm panel prepare_prev_first flag so-that the previous
controller should be prepared first before the prepare for the
panel is called.
samsung-s6e3ha2, samsung-s6e63j0x03 and samsung-s6e8aa0 are the

This makes sure that the previous controller, likely to be a DSI

These panels communicate brightness in big endian. This is not a quirk
of the panels themselves, but rather, a part of the MIPI standard. Use
the new mipi_dsi_dcs_set_display_brightness_large() function that
properly handles 16-bit brightness instead of doing special processing
of the brightness values.

Include <linux/of.h> in source files that need it. Some of DRM's
source code gets OF header via drm_crtc_helper.h and <linux/fb.h>,
which can leed to unnecessary recompilation.
In drm_modes.c, add a comment on the reason for still including
<linux/fb.h>. The header file is required to get KHZ2PICOS(). The
macro is part of the UAPI headers, so it cannot be moved to a less
prominent location.
v2:
* include <linux/of.h> in komeda_drv.c (kernel test robot)

Add support for the 1080x2400 Visionox VTDR6130 AMOLED DSI panel
found on the Qualcomm SM8550 MTP board.
By default the the panel is configured to work with DSI compressed
streams, but can work in uncompressed video mode since 1080x2400 in
RGB888 fits in the 4 DSI lanes bandwidth.
While display compression is preferred for performance and power
reasons, let's start with the uncompressed video mode support and
add the DSC support later on.
