The device tree is passed to the kernel by the boot loader. Most ARM devices use U-boot at bootloader. Usually the u-boot configuration selects the correct device tree for the device. But it is possible to enter some commands to load a different device tree.
When the system boots, U-boot usually prompts a message like "Press any key to abort auto-boot..." (on some devices this is only visible on the serial console)
From there you can enter the "printenv" command to see its current settings, and adjust the boot commands, such as which device tree is being loaded. The enviorement should contain a variable
fdt_file, which contains the filename of the device tree to load.
When using the mainline kernel, the device trees sit in /boot/dtbs/ The Asus Flip is based on the veyron board design. Looking at the device trees shipped with the mainline package, a number of trees come into consideration:
/boot/dtbs/rk3288-veyron-brain.dtb
/boot/dtbs/rk3288-veyron-jaq.dtb
/boot/dtbs/rk3288-veyron-jerry.dtb
/boot/dtbs/rk3288-veyron-mickey.dtb
/boot/dtbs/rk3288-veyron-minnie.dtb
/boot/dtbs/rk3288-veyron-pinky.dtb
/boot/dtbs/rk3288-veyron-speedy.dtb
See what file is being loaded by default. According to this
