ILI7807S is a DSI display controller used to drive MIPI-DSI panels.
The DLC DLC0697 1080x1920 LCD panel is based on this controller.

The panel requires a reset GPIO, backlight enable GPIO, I/O voltage

If panel requires it, so should the binding.

Ack, I will update.

What is the name of the pin in ili7807s device?

Display daughter card has WLED driver as well as LCD bias driver.

The WLED driver's Enable is coming from WLED_P1_EN and PWM is coming 
from LCD_CABC output of the panel.

WLED driver is not ili7807s. LCD bias driver also sounds like something
else than ili7807s.

So my question stays.
