ARM: dts: stm32: add support for art-pi board based on stm32h750xbh6
This patchset has following changes: - introduce stm32h750.dtsi to support stm32h750 value line - add pin groups for usart3/uart4/spi1/sdmmc2 - add stm32h750i-art-pi.dtb (arch/arm/boot/dts/Makefile) - add stm32h750i-art-pi.dts to support art-pi board - add stm32h750i-art-pi-u-boot.dtsi to support art-pi board (u-boot) art-pi board component: - 8MiB qspi flash - 16MiB spi flash - 32MiB sdram - ap6212 wifi&bt&fm the detail board information can be found at: https://art-pi.gitee.io/website/ Signed-off-by: dillon min <dillon.minfei@gmail.com> Reviewed-by: Patrice Chotard <patrice.chotard@foss.st.com>
