There is also "i2c-gpio,timeout-ms" already.

Basically same question goes for "slave-addr". Since I2C is
multi-master, an I2C controller may also be slave (not that we support
that in the I2C core yet, but drivers could have that implemented on
their own). We have "samsung,i2c-slave-addr" already.
