Hi @Wjian.1

For clock management on STM32MP157 please refer to wiki :

https://wiki.st.com/stm32mpu/wiki/Clock_overview

https://wiki.st.com/stm32mpu/wiki/Clock_device_tree_configuration

For HDMI :

https://wiki.st.com/stm32mpu/wiki/How_to_display_on_HDMI

STM32CubeMX can be used to generate the clock tree as per your need.

Hope it help,

Olivier
