Oh, OK. I see what you mean. I'm still very new to this process,
so it takes some practice to "learn the customs". Thanks for
clarifying.
So, in future I will keep those explanations below the "---" line.

=== Note: this patch depends on the previous patch titled
=== "[PATCH] I2C: Zynq: Support for 0-length register address"
=== submitted 24 Sep. 2013.
Tested on Xilinx ZC702 eval board:
Select various I2C chips using
Xilinx repo. (That's because the Xilinx
repo has config files for several individual boards, but the mainline repo
doesn't yet have those files.)
