gpio_defaults needs to be specified as an unsigned int rather than an int, because the intention of the DT binding is that all out of range values for a 16-bit register will cause the defaults to be used, however, if gpio_defaults is an int then values that are larger than INT_MAX will become negative numbers and be written out directly to the hardware. As no where in the code replies on gpio_defaults being an int, the simplest fix is to just change it to unsigned.
