d8eb00bbc6 drm/panel: kingdisplay-kd097d04: Disable EoTp 
Since commit d97e71e449 ("drm/bridge: synopsys: dw-mipi-dsi: enable EoTp by
default") panel output on an Acer Chromebook Tab 10 (google-dru) is corrupted.
The tablet I use is equipped with a kingdisplay-kd097d04 panel, disabling EoTp
restores the correct functionality.

056d76f7cb drm/panel: sitronix-st7789v: fix sync flags for t28cp45tn89 
I planned to set the polarity of horizontal and vertical sync, but
accidentally described vertical sync twice with different polarity
instead.

Note, that there is no functional change, because the driver only
makes use of DRM_MODE_FLAG_P[HV]SYNC to divert from the default
active-low polarity.

5efa824920 drm/panel: ilitek-ili9881c: move display_on/_off dcs calls to (un-)prepare 
At least for panel-bridges, the atomic_enable call is defined as being
called right after the preceding element in the display pipe is enabled.

It is also stated that "The bridge can assume that the display pipe (i.e.
clocks and timing signals) feeding it is running when this callback is
called"

This means the DSI controller driving this display would have already
switched over to video-mode from command mode and thus dcs functions
should not be called anymore at this point.

This caused a non-working display for me, when trying to enable
the rk3576 dsi controller using a display using this controller.

Therefore move the display_on/off calls the more appropriate
prepare/unprepare callbacks.

47d7953d8e drm: panel: add support for Samsung AMS561RA01 panel with S6E8AA5X01 controller 
Samsung AMS561RA01 is an AMOLED panel, using the Samsung S6E8AA5X01 MIPI
DSI controller. Implement a basic panel driver for such panels.

The driver also initializes a backlight device, which works by changing
the panel's gamma values and aid brightness levels appropriately, with
the help of look-up tables acquired from downstream kernel sources.

a6adf47d30 drm/panel: jdi-lpm102a188a: Fix bug and clean up driver 
Fix bug in unprepare() which causes the function's return value to be
that of the last mipi "enter sleep mode" command.

Update driver to use the "multi" variant of MIPI functions in order to
facilitate improved error handling and remove the panel's dependency on
deprecated MIPI functions.

Use the new mipi_dsi_dual macro to reduce code duplication.

d94a2a00d2 drm: Create mipi_dsi_dual* macros 
Create mipi_dsi_dual, mipi_dsi_dual_dcs_write_seq_multi, and
mipi_dsi_dual_generic_write_seq_multi macros for panels which are driven
by two parallel serial interfaces. This allows for the reduction of code
duplication in drivers for these panels.

Remove mipi_dsi_dual_dcs_write_seq_multi definition from
panel-novatek-nt36523.c to avoid the duplicate definition. Make novatek
driver pass mipi_dsi_context struct as a pointer.

1511d3c4d2 drm/panel-edp: Add 50ms disable delay for four panels 
Add 50ms disable delay for NV116WHM-N49, NV122WUM-N41, and MNC207QS1-1
to satisfy T9+T10 timing. Add 50ms disable delay for MNE007JA1-2
as well, since MNE007JA1-2 copies the timing of MNC207QS1-1.

Specifically, it should be noted that the MNE007JA1-2 panel was added
by someone who did not have the panel documentation, so they simply
copied the timing from the MNC207QS1-1 panel. Adding an extra 50 ms
of delay should be safe.

95ec5c606d drm/panel/khadas-ts050: Use refcounted allocation in place of devm_kzalloc() 
Move to using the new API devm_drm_panel_alloc() to allocate the
panel. In the call to the new API, avoid using explicit type and use
__typeof() for more type safety.

1a304a2f8f drm/panel-edp: Add BOE NE14QDM panel for Dell Latitude 7455 
Cannot confirm which variant exactly it is, as the EDID alphanumeric data
contains '0RGNR' <0x80> 'NE14QDM' and ends there; but it's 60 Hz and with
touch.

I do not have access to datasheets for these panels, so the timing is
a guess that was tested to work fine on this laptop.

691674a282 drm/panel: raydium-rm67200: Move initialization from enable() to prepare stage 
The DSI host has different modes in prepare() and enable() functions,
prepare() is in LP command mode and enable() is in HS video mode.

>From our experience, generally the initialization sequence needs to be
sent in the LP command mode.

Move the setup init function from enable() to prepare() to fix a display
shift on rk3568 evb.

Tested on rk3568/rk3576/rk3588 EVB.

941461216c drivers/panel: raydium-rm67200: Make reset-gpio optional 
Although the datasheet of the panel module describes that it has a
reset pin, in the actual hardware design, we often use an RC circuit
to control the reset, and rarely use GPIO to control the reset. This
is the way it is done on our numerous development boards (such as
RK3568/RK3576 EVB).

So make the reset-gpio optional.
