| Device driver initialization priority. Must be higher than |
| CONFIG_I2C_INIT_PRIORITY so the I2C bus is available, and |
| higher than any GPIO controller hosting the INT line. |

| help |
| When a node has no int-gpios property, the driver polls the |
| chip's input register at this period to detect transitions. |
| Used for boards without a described usable INT line; ignored |
| otherwise. |
