I came across an example u-boot configuration for LCD screen:
https://github.com/Openvario/meta-openvario/blob/warrior/recipes-bsp/u-boot/files/openvario-57-lvds/openvario_defconfig
especially
CONFIG_VIDEO_LCD_MODE="x:640,y:480,depth:18,pclk_khz:25000,hs:1,vs:1,le:157,ri:2,up:42,lo:2,sync:3,vmode:0"
CONFIG_VIDEO_LCD_PANEL_LVDS=y
CONFIG_VIDEO_LCD_BL_PWM="PB2"
CONFIG_VIDEO_LCD_BL_PWM_ACTIVE_LOW=n
We'd still need to get the timing parameters (CONFIG_VIDEO_LCD_MODE) for the Pinebook Pro (from the panel datasheet).
And that's if that thing is connected via LVDS in the first place.
But that's all moot if your Pinebook Pro is bricked for good.
