Can we use similar format to other files in the directory?

I guess we don't need to know type of the compatible atribute, other
files say

Required properties:

- compatible : Must be "skyworks,aat1290".
- flen-gpios : Must be device tree identifier of the flash device
...

which is easier to understand.
