-Subject: Initial device tree
-
- Tested using clearfrog u-boot
- Increase SD Card clock to 50 MHz from default 25 MHz
- All 7 LED declared as led-gpio
- LED1 (system) default to hearbeat
- LED7 (USB) triggered by USB Host activity
- SPI NOR flash declared as MTD
- Enable IO expander interrupt
- Allocate GPIOs for fans
