STM32U5G9J-DK2 NeoChrom Zephyr LVGL Compatibility

Hello everyone,
here are my questions:

1. Is there any roadmap or community effort to add NeoChrom/GPU2D support to Zephyr?
2. Has anyone successfully integrated the STM32 HAL GPU2D driver alongside Zephyr?
3. Would it be possible to:
- Initialize GPU2D using HAL in the Zephyr application
- Patch Zephyr's LVGL Kconfig to expose Nema GFX options
- Use LVGL's existing lv_draw_nema_gfx_stm32_hal.c backend
4. Are there any technical blockers (interrupt conflicts, clock management, memory mapping) that would prevent this hybrid approach?

I'm willing to contribute if there's guidance on the proper implementation approach.

Thank you for any insights.
