34 Please also consider enabling the gameport on the card in the ->open()
35 callback if the io is mapped to ISA space - this way it'll occupy the io
37 ->close() callback. You also can select the io address in the ->open()
70 the driver doesn't have to measure them the old way - an ADC is built into

95 experimentation, it is the amount of noise in the ADC data. Perfect
97 See analog.c and input.c for handling of fuzz - the fuzz value determines

107 more than one gameport instance simultaneously, use the ->private member of
108 the gameport struct to point to your data.
147 I/O address for use with raw mode. You have to either set this, or ->read()
161 represents the amount of noise in the data. See
