Problem using the driver ST7789V in TFT display

Question

Hello,

I have a waveshare 1.69’ LCD display with the ST7789V2 driver and I'm trying to get it to work with the nRF54L15-DK board using the ST7789V driver on zephyr (docs.zephyrproject.org/.../sitronix,st7789v.html). I used the nRF54L15-DK board because it allows you to increase the spi speed up to 32 MHz.
To interact with the display, I'm trying to use the LVGL library. (https://docs.nordicsemi.com/bundle/ncs-1.8.0/page/kconfig/CONFIG_LVGL.html)

Sdk version: 2.9.1
Toolchain: 2.9.1
Board: nRF54L15 dk
Display: 1.69" LCD (240x280); ST7789V2 driver

For the overlay file, I based it on some posts on devzone:

With these files, the code compiles and flashes, but when I look at the terminal the following error appears:

Could you please help me resolve this issue?
Other question, with this overlay file configuration how I configure backlight pin of display ?

Thanks,
