given some stm32mp157 boards do have a dsi display, i was wondering how to write pixels?

any hints in the right direction?

thanks for this great repository!

I would start by looking at the H7 DSI peripheral: https://github.com/STMicroelectronics/stm32h7xx-hal-driver/blob/66e5110cb6c7f7d997303db329de83edc2800dae/Src/stm32h7xx_hal_dsi.c

Maybe some of the H7 example projects can shed light on how to configure that, e.g.: https://github.com/STMicroelectronics/STM32CubeH7/tree/master/Projects/STM32H743I-EVAL/Examples/LTDC

The only experience I have with screens on the MP1 is driving a small screen via SPI.

I did this a while back. You can look at the example in my fork. https://github.com/cody84/stm32mp1-baremetal/tree/master/examples/dk2_dsi-lvgl
