[PATCH 12/14] ARM: dts: Introduce STM32F429 MCU
From: Maxime Coquelin
Date: Thu Feb 12 2015 - 12:46:58 EST
The STMicrolectornics's STM32F419 MCU has the following main features:
- Cortex-M4 core running up to @180MHz
- 2MB internal flash, 256KBytes internal RAM
- FMC controller to connect SDRAM, NOR and NAND memories
- SD/MMC/SDIO support
- Ethernet controller
- USB OTFG FS & HS controllers
- I2C, SPI, CAN busses support
- Several 16 & 32 bits general purpose timers
- Serial Audio interface
- LCD controller
