HI Kinsy,

I study stm32h7 as a learning reference for my GSoC project so i dont have stm32h7 board yet but,

I tested HAL_SPI_MspInit using a unit test with mocked GPIO functions.\
The test verified:

* SPI pins (SCK/MISO/MOSI) are initialized in correct order.
* CS pins on the same port are combined correctly.
* Pins are set HIGH before configuring as output.
* Pins with regs== NULL are skipped.

Output logs confirm correct behavior without requiring hardware.
