[PATCH v6 6/9] ARM: dts: stm32: add support for art-pi board based on stm32h750xbh6

From: dillon . minfei
Date: Fri Mar 26 2021 - 07:16:20 EST

From: dillon min <dillon.minfei@xxxxxxxxx>

This patchset has following changes:

- introduce stm32h750.dtsi to support stm32h750 value line
- add stm32h750i-art-pi.dtb (arch/arm/boot/dts/Makefile)
- add dts binding usart3 for bt, uart4 for console
usart3/uart4 pinctrl in stm32h7-pinctrl.dtsi
usart3/uart4 register in stm32h743.dtsi
- add dts binding sdmmc2 for wifi
sdmmc2 pinctrl in stm32h7-pinctrl.dtsi
sdmmc2 register in stm32h743.dtsi
- add spi1 pinctrl in stm32h7-pinctrl.dtsi for spi flash
- add stm32h750-art-pi.dts to support art-pi board
- add pinctrl: pin-controller@58020000 {} to fix dtbs_check warrnings

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/
