Move to using the new API devm_drm_panel_alloc() to allocate the

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.

prepare() is in LP command mode and enable() is in HS video mode.
>From our experience, generally the initialization sequence needs to be

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.

The empty panel_dpi struct was only ever used as a discriminant, but
it's kind of a hack, and with the reworks done in the previous patches,
we shouldn't need it anymore.
Let's get rid of it.

Commit de04bb0089a9 ("drm/panel/panel-simple: Use the new allocation in
place of devm_kzalloc()") moved the call to drm_panel_init into the
devm_drm_panel_alloc(), which needs a connector type to initialize
properly.
In the panel-dpi compatible case, the passed panel_desc structure is an
empty one used as a discriminant, and the connector type it contains
isn't actually initialized.
It is initialized through a call to panel_dpi_probe() later in the
function, which used to be before the call to drm_panel_init() that got
merged into devm_drm_panel_alloc().
So, we do need a proper panel_desc pointer before the call to
devm_drm_panel_alloc() now. All cases associate their panel_desc with
the panel compatible and use of_device_get_match_data, except for the
panel-dpi compatible.
In that case, we're expected to call panel_dpi_probe, which will
allocate and initialize the panel_desc for us.
Let's create such a helper function that would be called first in the
driver and will lookup the desc by compatible, or allocate one if
relevant.

In order to fix the regession introduced by commit de04bb0089a9
("drm/panel/panel-simple: Use the new allocation in place of
devm_kzalloc()"), we need to move the panel_desc lookup into the common
panel_simple_probe() function.
There's two callers for that function, the probe implementations of the
platform and MIPI-DSI drivers panel-simple implements.
The MIPI-DSI driver's probe will need to access the current panel_desc
to initialize properly, which won't be possible anymore if we make that
lookup in panel_simple_probe().
However, we can make panel_simple_probe() return the initialized
panel_simple structure it allocated, which will contain a pointer to the
associated panel_desc in its desc field.
This doesn't fix de04bb0089a9 ("drm/panel/panel-simple: Use the new
allocation in place of devm_kzalloc()") still, but makes progress
towards that goal.

If the panel-simple driver is probed from a panel-dpi compatible, the
driver will use an empty panel_desc structure as a descriminant. It
will then allocate and fill another panel_desc as part of its probe.
However, that allocation needs to happen after the panel_simple
structure has been allocated, since panel_dpi_probe(), the function
doing the panel_desc allocation and initialization, takes a panel_simple
pointer as an argument.
This pointer is used to fill the panel_simple->desc pointer that is
still initialized with the empty panel_desc when panel_dpi_probe() is
called.
Since commit de04bb0089a9 ("drm/panel/panel-simple: Use the new
allocation in place of devm_kzalloc()"), we will need the panel
connector type found in panel_desc to allocate panel_simple. This
creates a circular dependency where we need panel_desc to create
panel_simple, and need panel_simple to create panel_desc.
Let's break that dependency by making panel_dpi_probe simply return the
panel_desc it initialized and move the panel_simple->desc assignment to
the caller.
This will not fix the breaking commit entirely, but will move us towards
the right direction.

The Winstar wf40eswaa6mnn0 panel is a square 4.0" TFT LCD with a
resolution of 480x480 pixels.
This panel is driven by the Sitronix ST7701 controller and uses a MIPI
DSI interface. The settings are based on the panel's datasheet and the
init sequence provided by Winstar.
It was tested on a Verdin iMX8MP from Toradex with a Carrier Board
providing a MIPI DSI interface.

It's unclear why I originally wrote in the description of
`prepare_to_enable` that "This is not specified in a standard way on
eDP timing diagrams" and then also wrote "It is effectively the time
from HPD going high till you can turn on the backlight." It seems
pretty clear that it's (T4+T5+T6+T8)-min. Either I was confused when I
wrote this or I was looking at some strange panel datasheet that I can
no longer find.
Update the description of the field so it's easier for people to fill
this in. Couch the description with "usually" in case there really was
some weird datasheet where things were specified in a different way.

Timings taken from the datasheet and the display is working in DE mode,
thus the datasheet only specifies the blanking period. sync, back porch
and front porch are arbitrarily chosen.
The datasheet can be found at [1] but for reference these are the
relevant timings:
sym | | min | typ | max | unit |
------|--------------+------+------+------+------+
Tv | V period | 1094 | 1130 | 1836 | Th |
| V active | 1080 | 1080 | 1080 | Th |
| V blanking | 14 | 50 | 756 | Th |
Fv | V frequency | 49 | 60 | 76 | Hz |
Th | H period | 1000 | 1050 | 1678 | Tclk |
| H active | 960 | 960 | 960 | Tclk |
| H blanking | 40 | 90 | 718 | Tclk |
Fh | H frequency | 53.7 | 67.8 | 90.0 | kHz |
Tclk | LVDS clock | 53.7 | 71.2 | 90.0 | MHz |
Keep in mind that this is a dual link LVDS panel and the horizontal
timings are only for one half of the panel.
