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.
