8a4f5e1185 drm/panel-simple: fix connector type for newhaven_nhd_43_480272ef_atxl 
Add connector type for newhaven_nhd_43_480272ef_atxl, as
drm_panel_bridge_add() requires connector type to be set.

efb9479085 drm/panel-simple: fix connector type for LogicPD Type28 Display 
The LogicPD Type28 display used by several Logic PD products has not
worked since v5.6.

The connector type for the LogicPD Type 28 display is missing and
drm_panel_bridge_add() requires connector type to be set.

48834e6084 drm/panel-simple: Support hpd-gpios for delaying prepare() 
People use panel-simple when they have panels that are builtin to
their device.  In these cases the HPD (Hot Plug Detect) signal isn't
really used for hotplugging devices but instead is used for power
sequencing.  Panel timing diagrams (especially for eDP panels) usually
have the HPD signal in them and it acts as an indicator that the panel
is ready for us to talk to it.

Sometimes the HPD signal is hooked up to a normal GPIO on a system.
In this case we need to poll it in the correct place to know that the
panel is ready for us.  In some system designs the right place for
this is panel-simple.

When adding this support, we'll account for the case that there might
be a circular dependency between panel-simple and the provider of the
GPIO.  The case this was designed for was for the "ti-sn65dsi86"
bridge chip.  If HPD is hooked up to one of the GPIOs provided by the
bridge chip then in our probe function we'll always get back
-EPROBE_DEFER.  Let's handle this by allowing this GPIO to show up
late if we saw -EPROBE_DEFER during probe.  NOTE: since the
gpio_get_optional() is used, if the "hpd-gpios" isn't there our
variable will just be NULL and we won't do anything in prepare().

cfe40d0223 panel: simple: Add BOE NV133FHM-N62 
All info I could find about this panel show that it behaves the same
as the BOE NV133FHM-N61.  However, it definitely appears to be a
unique panel because reading the EDID shows "NV133FHM-N62".  We'll add
a string match for the new panel but until we find something unique
about it we'll just point at the N61's structures.

9694d9c3b5 panel: simple: Fix size and bpp of BOE NV133FHM-N61 
The BOE NV133FHM-N61 is documented in the original commit to be a
13.3" panel, but the size listed in our struct doesn't match.
Specifically:

  math.sqrt(30.0 * 30.0 + 18.7 * 18.7) / 2.54 ==> 13.92

Searching around on the Internet shows that the size that was in the
structure was the "Outline Size", not the "Display Area".  Let's fix
it.

Also the Internet says that this panel supports 262K colors.  That's
6bpp, not 8bpp.

There are two variants of the COM37H3M panel.
The older one's COM37H3M05DTC data sheet specifies:

                         MIN      TYP     MAX
CLK frequency    fCLK     --       22.4    26.3 MHz (in VGA mode)
VSYNC Frequency  fVSYNC   54       60      66   Hz
VSYNC cycle time tv       --      650      --   H
HSYNC frequency  fHSYNC   --       39.3    --   kHz
HSYNC cycle time th       --      570      --   CLK

The newer one's COM37H3M99DTC data sheet says:

                         MIN      TYP     MAX
CLK frequency    fCLK     18       19.8    27   MHz
VSYNC Frequency  fVSYNC   54       60      66   Hz
VSYNC cycle time tv      646      650     700   H
HSYNC frequency  fHSYNC  --        39.0    50.0 kHz
HSYNC cycle time th      504      508     630   CLK

So we choose a parameter set that lies within the specs
of both variants. We start at .vrefresh = 60,
choose .htotal = 570 and .vtotal = 650 and end up
in a clock of 22.230 MHz.

7e4f6fb354 Revert "drm/panel: simple: Add support for Sharp LQ150X1LG11 panels" 
This reverts commit 0f9cdd743f.

The interface of the panel is LVDS, not parallel.
The color depth is RGB888, not RGB565.
The panel has additional features, making it not so simple.
The only user (upstream) of this panel is appropriately using panel-lvds.

4a1d0dbc83 drm/panel: simple: add panel-dpi support 
The panel-dpi compatible is a fallback that
allows the DT to specify the timing.

When matching panel-dpi expect the device tree to include the
timing information for the display-panel.

Background for this change:
There are a lot of panels and new models hits the market very often.
It is a lost cause trying to chase them all and users of new panels
will often find them in situations that the panel they ues are not
supported by the kernel.
On top of this a lot of panels are customized based on customer
specifications.

Including the panel timing in the device tree allows for a simple
way to describe the actual HW and use this description in a generic
way in the kernel.
This allows uses of proprietary panels, or panels which are not
included in the kernel, to specify the timing in the device tree
together with all the other HW descriptions.
And thus, using the device tree it is then easy to add support
for an otherwise unknown panel.

The current support expect panels that do not require any
delays for prepare/enable/disable/unprepare.

I've just tested this patch on Apalis iMX6Q and Colibri iMX7D using

The NT35510 can be used with both internal and external

if no external backlight is found, we register a subdriver
for the internal backlight.

The panel datasheet says that the panel samples at falling edge, but
does not say anything about h/v sync signals. Testing shows that if the
sync signals are driven on falling edge, the picture on the panel will
be slightly shifted right.

Setting sync drive edge to the same as data drive edge fixes this issue.
