[PATCH v2 7/8] ARM: dts: stm32: add STM32MP1-based Linux Automation MC-1 board

From: Ahmad Fatoum
Date: Thu Mar 26 2020 - 18:03:03 EST

The Linux Automation MC-1 is a SBC built around the Octavo Systems
OSD32MP15x SiP. The SiP features up to 1 GB DDR3 RAM, EEPROM and
a PMIC. The board has eMMC and a SD slot for storage and GbE
for both connectivity and power.

Signed-off-by: Ahmad Fatoum <a.fatoum@xxxxxxxxxxxxxx>
---
v1 -> v2:
- rebased on stm32-next
- moved pinctrl groups to stm32mp15-pinctrl (Alex)
- added sleep pinctrl groups
- moved enabling &gpu into SoC DTSI (Lucas)
- sorted nodes alphabetically (Alex)
- removed default-state from LED that already has linux,default-trigger
