We already have those bindings from the designware driver:

 - i2c-sda-hold-time-ns : should contain the SDA hold time in nanoseconds.
 - i2c-scl-falling-time : should contain the SCL falling time in nanoseconds.
 - i2c-sda-falling-time : should contain the SDA falling time in nanoseconds.

Can you reuse them? Or do you really need a specific rise-time property?
If so, please matche the style of the bindings above.
