Fri Apr 2 10:42:39 CEST 2021
From: dillon min <dillon.minfei at gmail.com>
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/
