1319f2178b drm/panel-simple: add Evervision VGG644804 panel entry 
Timings taken from the datasheet, although sometimes there are just
typical values and it's not clear if they are no min and max values or
if you must use the typical value exactly. To make things worse, there
is no back porch but only a combined sync and back porch length.

Unfortunately, there is not public datasheet. Therefore, here are the
relevant timings:
                 | min |  typ   | max |
-----------------+-----+--------+-----+
CLK frequency    |  -  | 25.175 |  -  |
HS period        |  -  |   800  |  -  |
HS pulse width   |  5  |    30  |  -  |
HS-DEN time      | 112 |   144  | 175 |
DEN pulse width  |  -  |   640  |  -  |
VS pulse width   |  1  |     3  |  5  |

cea7008190 drm/panel: boe-tv101wum-nl6: Fine tune Himax83102-j02 panel HFP and HBP 
The refresh reported by modetest is 60.46Hz, and the actual measurement
is 60.01Hz, which is outside the expected tolerance. Adjust hporch and
pixel clock to fix it. After repair, modetest and actual measurement were
all 60.01Hz.

Modetest refresh = Pixel CLK/ htotal* vtotal, but measurement frame rate
is HS->LP cycle time(Vblanking). Measured frame rate is not only affecte
by Htotal/Vtotal/pixel clock, also affected by Lane-num/PixelBit/LineTime
/DSI CLK. Assume that the DSI controller could not make the mode that we
requested(presumably it's PLL couldn't generate the exact pixel clock?).
If you use a different DSI controller, you may need to readjust these
parameters. Now this panel looks like it's only used by me on the MTK
platform, so let's change this set of parameters.

5820a1932c drm/panel: ili9882t: Avoid blurred screen from fast sleep 
At present, we have found that there may be a problem of blurred
screen during fast sleep/resume. The direct cause of the blurred
screen is that the IC does not receive 0x28/0x10. Because of the
particularity of the IC, before the panel enters sleep hid must
stop scanning, as i2c_hid_core_suspend before ili9882t_disable.
If move the ili9882t_enter_sleep_mode function to ili9882t_unprepare,
touch reset will pull low before panel entersleep, which does not meet
the timing requirements.. So in order to solve this problem, the IC
can handle it through the exception mechanism when it cannot receive
0x28/0x10 command. Handling exceptions requires a reset 50ms delay.
Refer to vendor detailed analysis [1].

Ilitek vendor also suggested switching the page before entering sleep to
avoid panel IC not receiving 0x28/0x10 command.

Note: 0x28 is display off, 0x10 is sleep in.

e2450d32e5 drm/panel: ili9882t: Break out as separate driver 
The Starry ILI9882t-based panel should never have been part of the boe
tv101wum driver, it is clearly based on the Ilitek ILI9882t display
controller and if you look at the custom command sequences for the
panel these clearly contain the signature Ilitek page switch (0xff)
commands. The hardware has nothing in common with the other panels
supported by this driver.

Break this out into a separate driver and config symbol instead.

If the placement here is out of convenience for using similar code,
we should consider creating a helper library instead.

0ddd30471a drm/panel: st7703: Fix timings when entering/exiting sleep 
Fix flickering of the pinephone's XDB599 panel that happens after
resume.

Extend the delay after issuing the command to exit sleep mode from 60 to
120 msec as per the controller's specification.

Introduce a 120 msec delay after issuing the command to enter sleep
mode. This is needed in order for the controller to reliably finalize
the sleep in sequence before switching of power supply.

In contrast to the JH057N panel, the XBD599 panel does not require a 20
msec delay after initialization and exiting sleep mode. Therefore, move
the delay into the already existing device specific initialization
function.

The XDB599 does not require a 20 msec delay between the SETBGP and
SETVCOM commands. Therefore, remove the delay from the device specific
initialization function.

There also needs to be a delay after enabling the supplies and before

reach the required voltage. Use 10-20ms to also give the power supplies
some time to reach the required voltage, too.

This fixes intermittent panel initialization failures and screen

ad3e33fe07 drm/panel: Move AUX B116XW03 out of panel-edp back to panel-simple 
In commit 5f04e7ce39 ("drm/panel-edp: Split eDP panels out of
panel-simple") I moved a pile of panels out of panel-simple driver
into the newly created panel-edp driver. One of those panels, however,
shouldn't have been moved.

As is clear from commit e35e305eff ("drm/panel: simple: Add AUO
B116XW03 panel support"), AUX B116XW03 is an LVDS panel. It's used in
exynos5250-snow and exynos5420-peach-pit where it's clear that the
panel is hooked up with LVDS. Furthermore, searching for datasheets I
found one that makes it clear that this panel is LVDS.

As far as I can tell, I got confused because in commit 88d3457ceb
("drm/panel: auo,b116xw03: fix flash backlight when power on") Jitao
Shi added "DRM_MODE_CONNECTOR_eDP". That seems wrong. Looking at the
downstream ChromeOS trees, it seems like some Mediatek boards are
using a panel that they call "auo,b116xw03" that's an eDP panel. The
best I can guess is that they actually have a different panel that has
similar timing. If so then the proper panel should be used or they
should switch to the generic "edp-panel" compatible.

When moving this back to panel-edp, I wasn't sure what to use for
.bus_flags and .bus_format and whether to add the extra "enable" delay
from commit 88d3457ceb ("drm/panel: auo,b116xw03: fix flash
backlight when power on"). I've added formats/flags/delays based on my
(inexpert) analysis of the datasheet. These are untested.

NOTE: if/when this is backported to stable, we might run into some
trouble. Specifically, before 474c162878 ("arm64: dts: mt8183:
jacuzzi: Move panel under aux-bus") this panel was used by
"mt8183-kukui-jacuzzi", which assumed it was an eDP panel. I don't
know what to suggest for that other than someone making up a bogus
panel for jacuzzi that's just for the stable channel.

258dd5e6e6 drm/panel: boe-tv101wum-nl6: Completely pull GPW to VGL before TP term 
The sta_himax83102 panel sometimes shows abnormally flickering
horizontal lines. The front gate output will precharge the X point of
the next pole circuit before TP(TouchPanel Enable) term starts, and wait
until the end of the TP term to resume the CLK. For this reason, the X
point must be maintained during the TP term. In abnormal case, we
measured a slight leakage at point X. This because during the TP term,
the GPW does not fully pull the VGL low, causing the TFT to not be
closed tightly.

To fix this, we completely pull GPW to VGL before entering the TP term.
This will ensure that the TFT is closed tightly and prevent the abnormal
display.

underlying vendor is unknown/unmarked (at least not visible in a

sequences and timings in the BSP kernel, but works fine with the
same ones used in the existing driver. The panel will not work without
the inclusion of the MIPI_DSI_CLOCK_NON_CONTINUOUS flag, and this flag
prevents the 353 series from working correctly, so a new compatible
string is added.
