 device-tree/ directory contains examples
 
+to use device trees, do something like:
+
+	vi device-tree/gpio-leds.dts
+	armbian-add-overlay device-tree/gpio-led.dts
+	dmesg -w &
+	./overlay-load.sh /boot/overlay-user/gpio-led.dtbo
+
+
+To load kernel module for i2c sensors without writing device tree
+echo module_name address into i2c bus:
+
+echo lm75 0x49 > /sys/bus/i2c/devices/i2c-1/new_device
+
+
+
 i2c-usersapce/ contains random i2c userspace device drivers
