- remove backlight from panel driver
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.

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.

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.

Auo,auo,b101uan08.3's connector is same as boe,tv101wum-nl6.
The most codes can be reuse.
So auo,b101uan08.3 and boe,tv101wum-nl6 use one driver file.
Add the different parts in driver data.

Hi Jitao.
A few comments that I missed in last round.
Please consider to combine the three panels in one binding.
I realise they are almost identical so no need for three binding files.

Please use (GPL-2.0-only OR BSD-2-Clause) for all new bindings.

Rob is not a typical maintainer of panel bindings.
The fallback it Thierry and me.
But if you have agreed this with Rob then all is good.

I would be suprised if backlight is a required node.
You could always tie the input to a fixed voltage and then no backlight
node are required.
Please remove from the required list unless you can convince me
otherwise.
