Fri Mar 26 11:24:23 CET 2021
From: dillon min <dillon.minfei at gmail.com>
All these files are add for support rt-thread art-pi board
the detail board information can be found at:
https://art-pi.gitee.io/website/
board resources:
- stm32h750xbh6 128k flash, 1024k sram
- 32MiB sdram
- 16MiB spi flash
- 8MiB qspi flash
- onboard wifi, bt, fm
Add following changes to sync with kernel device tree files:
- add stm32h7-pinctrl.dtsi to include pin defines for all stm32h743/50 boards
- add stm32h7(5/3)0-pinctrl.dtsi
- move gpio(a..k) register defines to stm32h743.dtsi, sync with kernel
- introduce stm32h750i-art-pi-u-boot.dtsi for sdram paramter, fmc pins
