This patchset has following changes:

- add stm32h750i-art-pi.dtb
- add dts binding usart3 for bt, uart4 for console
- add dts binding sdmmc2 for wifi
- add stm32h750-art-pi.dts to support art-pi board

board component:
- 8MiB qspi flash
- 16MiB spi flash
- 32MiB sdram
- ap6212 wifi&bt&fm

Those peripherals are available on h743 ?
Yes, available for stm32h743, but might not used by stm32h743i-disco board.
the difference between stm32h743xi and stm32h750xb:
  flash size:  2048/128,
ad convter : none/3
crypto-hash: none/aes,hmac,....

Ok, so perfect.
