Commit Message

Marcin Sloniewski July 1, 2020, 3:03 p.m. UTC
This commit adds device tree files supporting
SBC from Seeed Studio based on STM32MP157C.

This works with generic stm32mp1 config.
Right now only booting from SD card is supported.

Signed-off-by: Marcin Sloniewski <marcin.sloniewski at gmail.com>
---

Changes in v3:
- changed name of dts files from odyssey-stm32mp157c...
  to stm32mp157c-odyssey...
- removed usbotg node config
- add new board in dts/Makefile in alphabetical order

Changes in v2:
- removed `st,adc_usb_pd` from config since that
  adc connection is non-existent which caused
  warning or hang during boot
