Currently, only the 'i' 0x90 ioctl() actually exists and is defined in 'include/uapi/linux/iio/events.h'. It's the IIO_GET_EVENT_FD_IOCTL, which is used to retrieve and FD for reading events from an IIO device. We will want to add more ioct() numbers, so with this change the 'i' 0x90-0x9F space is reserved for IIO ioctl() calls.
