52 * @value: latest reported value for the axis.
53 * @minimum: specifies minimum value for the axis.
54 * @maximum: specifies maximum value for the axis.
55 * @fuzz: specifies fuzz value that is used to filter noise from
57 * @flat: values that are within this value will be discarded by
58 * joydev interface and reported as 0 instead.
59 * @resolution: specifies resolution for the values reported for
62 * Note that input core does not clamp reported values to the
63 * [minimum, maximum] limits, such task is left to userspace.
65 * Resolution for main axes (ABS_X, ABS_Y, ABS_Z) is reported in
66 * units per millimeter (units/mm), resolution for rotational axes
67 * (ABS_RX, ABS_RY, ABS_RZ) is reported in units per radian.

79 * struct input_keymap_entry - used by EVIOCGKEYCODE/EVIOCSKEYCODE ioctls
80 * @scancode: scancode represented in machine-endian form.
81 * @len: length of the scancode that resides in @scancode buffer.
82 * @index: index in the keymap, may be used instead of scancode
83 * @flags: allows to specify how kernel should handle the request. For
84 * example, setting INPUT_KEYMAP_BY_INDEX flag indicates that kernel
85 * should perform lookup in keymap by @index instead of @scancode
86 * @keycode: key code assigned to this scancode
88 * The structure is used to retrieve and modify keymap data. Users have
89 * option of performing lookup either by @scancode itself or by @index
90 * in keymap entry. EVIOCGKEYCODE will also return scancode or index
91 * (depending on which element was used to perform lookup).
