All the properties defined with two lines of statements.

Why cant they be with single line statement, like:

compatible: Must be "brcm,iproc-i2c"
reg: Define the base and range of the I/O address space that
contain the iProc I2C controller registers

....


I thought making them two lines are more readable (and obviously
that's very subjective, :)). But more importantly, it matches the
format of other Broadcom iProc/Cygnus devicetree binding documents
that are currently in progress of upstreaming.


But max of the bindings over the kernel follows single line statements.

Is it a requirement for these property descriptions to be one line? If not, I prefer to stick with the way it is now. Thanks.
