3.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Doug Anderson <dianders@chromium.org>
commit 8e2596e81a9dd8f9efcf78476f3990f211e25edb upstream.
In (6468276 i2c: designware: make SCL and SDA falling time configurable) new device tree properties were added for setting the falling time of SDA and SCL. The device tree bindings doc had a typo in it: it forgot the "-ns" suffix for both properies in the prose of the bindings.
I assume this is a typo because: * The source code includes the "-ns" * The example in the bindings includes the "-ns".
Fix the typo.
