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
|
|
- GPIO23 (MPP23) declared as GPIO button
|
|
- SPI NOR flash declared as MTD
|
|
- Enable IO expander interrupt
|
|
- Allocate GPIOs for fans
