The RK3588 uses TechPoint TP2855 to decode how the device tree is configured

[lantianhaohh]

Hello, I would like to ask, I use the image decoding chip techpoint TP2855 external four cameras in RK3588, using the code under your techpoint directory, how do I configure the device tree? What is my device tree configuration? Can you help me correct it? Thank you.
