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.
