7c8690d8fc drm/panel-edp: Add some panels with conservative timings 
These panels are used by Mediatek MT8173 Chromebooks, and they used to
work with the downstream v4.19 kernel without any specified delay.
Back in the v4.19 kernel, they used the "little white lie" approach,
which is making the devicetree claim a specific panel's compatible
string for many different panels. That was a common solution before the
generic edp-panel driver.

After we uprevved the device to a newer kernel and used the edp-panel
driver, we saw multiple devices reporting warnings of using an unknown
panel and falling back to the conservative timings, which means that
they turn on/off much more slowly than they should. We tried to fill in
the timings for those panels, but we failed to find all the data sheets
for them.

Therefore, instead of having them use the default conservative timings,
update them with less-conservative timings from other panels of the same
vendor. The panels should still work under those timings, and we can
save some delays and suppress the warnings.

4464af92f2 drm/panel-edp: Add powered_on_to_enable delay 
Add the support of powered_on_to_enable delay as the minimum time that
needs to have passed between the panel powered on and enable may begin.

This delay is seen in BOE panels as the minimum delay of T3+T4+T5+T6+T8
in the eDP timing diagrams.

6c9dbee84c drm/panel: ltk050h3146w: Set burst mode for ltk050h3148w 
The ltk050h3148w variant expects the horizontal component lane byte clock
cycle(lbcc) to be calculated using lane_mbps (burst mode) instead of the
pixel clock.
Using the pixel clock rate by default for this calculation was introduced
in commit ac87d23694 ("drm/bridge: synopsys: dw-mipi-dsi: Use pixel clock
rate to calculate lbcc") and starting from commit 93e82bb4de
("drm/bridge: synopsys: dw-mipi-dsi: Fix hcomponent lbcc for burst mode")
only panels that support burst mode can keep using the lane_mbps. So add
MIPI_DSI_MODE_VIDEO_BURST as part of the mode_flags for the dsi host.

799825aa87 drm/panel: st7701: Fix AVCL calculation 
The AVCL register, according to the datasheet, comes in increments
of -0.2v between -4.4v (represented by 0x0) to -5.0v (represented
by 0x3). The current calculation is done by adding the defined
AVCL value in mV to -4400 and then dividing by 200 to get the register
value. Unfortunately if I subtract -4400 from -4400 I get -8800, which
divided by 200 gives me -44. If I instead subtract -4400 from -4400
I get 0, which divided by 200 gives me 0. Based on the datasheet this
is the expected register value.

fb3f43d50d drm/panel-edp: Avoid adding multiple preferred modes 
If a non generic edp-panel is under aux-bus, the mode read from edid would
still be selected as preferred and results in multiple preferred modes,
which is ambiguous.

If both hard-coded mode and edid exists, only add mode from hard-coded.

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.

are some slight artifacts on the screen that go away over time. If
instead we hold the panel in reset status after it is unprepared,
this does not happen.

Currently the driver uses 29 lines.

Fix it, and since this panel is a DE panel, adjust the timings
to make them less hostile to controllers which cannot do 1 px
HSA/VSA, distribute the delays evenly between all three parts.
