LVDS pinout on the STM32MP257F-DK
Title shortened from "How do I know the pinout of the STM32MP25 chip that the LVDS interface on the STM32MP257F-DK development board connects to?"
Please see: How to write your question to maximize your chances to find a solution.
When we added an LCD screen driver to the STM32MP257F-DK development board, we consulted the Linux source code <arch/arm64/boot/dts/st/stm32mp25-pinctrl.dtsi> pin definition file and found that the chip pins corresponding to the LVDS interface on the development board did not seem to be defined in the file. However, when we consulted the <stm32mp257f.pdf> document, there are multiple pins with LCD multiplexing functions. How can I know which pin of the STM32MP25 chip the LVDS interface on the STM32MP257F-DK development board corresponds to? Or where can I get the hardware schematic diagram of the development board. Or maybe the official has defined the pin functions of the LVDS corresponding chip somewhere else. Please forgive my suspicion as a beginner, and thank you for your patient answer.
