Subject: [PATCH v7 0/8] add driver for "boe, tv101wum-nl6", "boe, tv101wum-n53", "auo, kd101n80-45na" and "auo, b101uan08.3" panels

Changes since v6:
- fix boe_panel_init err uninit.
- adjust the delay of backlight on.

Changes since v5:
- covert the documents to yaml
- fine tune boe, tv101wum-n53 panel video timine

Changes since v4:
- add auo,b101uan08.3 panel for this driver.
- add boe,tv101wum-n53 panel for this driver.

Changes since v3:
- remove check enable_gpio.
- fine tune the auo,kd101n80-45na panel's power on timing.

Changes since v2:
- correct the panel size
- remove blank line in Kconfig
- move auo,kd101n80-45na panel driver in this series.

Changes since v1:

- update typo nl6 -> n16.
- update new panel config and makefile are added in alphabetically order.
- add the panel mode and panel info in driver data.
- merge auo,kd101n80-45a and boe,tv101wum-nl6 in one driver

Subject: [PATCH v7 4/8] drm/panel: support for auo,kd101n80-45na wuxga dsi video mode panel

Auo,kd101n80-45na's connector is same as boe,tv101wum-nl6.
The most codes can be reuse.
So auo,kd101n80-45na and boe,tv101wum-nl6 use one driver file.
Add the different parts in driver data.

Boe,tv101wum-n53's connector is same as boe,tv101wum-nl6.
The most codes can be reuse.
So boe,tv101wum-n53 and boe,tv101wum-nl6 use one driver file.
Add the different parts in driver data.

I finally found some time to looks at this.

The bindings does unfortunately not pass a dt_binding_check

I had to locally do the following to make on of the bindings pass:

drm_panel has gained backlight support in drm-misc-next.

This function now takes drm_connector as second argument.

Here you will need to use connector->dev to get the drm_device.

There is no connector in drm_panel today.
Use the connector in supplied as second argument.

Move this after drm_panel_init and use drm_panel_of_backlight()

The binding say that backlight is mandatory. This is really not checked
here. And I *think* backlight is optional.

This should just be:

boe_panel_shutdown();
ret = mipi_dsi_detach();
if (ret < 0)
...
drm_panel_remove();

Please use drm_panel variants here.
And then I had expected to see:
drm_panel_disable();
drm_panel_unprepare();

This looks like a geneeral change.
Consider pushing to the initial commit.
