From: dillon min <[email protected]>
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

v7:
- remove stm32h750-pinctrl.dtsi as it's has same ball out and AF mux with
stm32h743, so just reuse stm32h743's pinctrl.
- stm32h750i-art-pi.dts changes to include "stm32h743-pinctrl.dtsi"
