In other words, &struct d9a254715 Hans Verkuil 2014-06-12 135 * v4l2_ext_control uses field p to point to the data. 998e76591 Hans Verkuil 2014-06-10 136 * @is_array: If set, then this control contains an N-dimensional array. 5626b8c75 Hans Verkuil 2011-08-26 137 * @has_volatiles: If set, then one or more members of the cluster are volatile. 5626b8c75 Hans Verkuil 2011-08-26 138 * Drivers should never touch this flag. 8ac7a9493 Hans Verkuil 2012-09-07 139 * @call_notify: If set, then call the handler's notify function whenever the 8ac7a9493 Hans Verkuil 2012-09-07 140 * control's value changes. 72d877cac Hans Verkuil 2011-06-10 141 * @manual_mode_value: If the is_auto flag is set, then this is the value 72d877cac Hans Verkuil 2011-06-10 142 * of the auto control that determines if that control is in 72d877cac Hans Verkuil 2011-06-10 143 * manual mode. So if the value of the auto control equals this 72d877cac Hans Verkuil 2011-06-10 144 * value, then the whole cluster is in manual mode. Drivers should 72d877cac Hans Verkuil 2011-06-10 145 * never set this flag directly. 0996517cf Hans Verkuil 2010-08-01 146 * @ops: The control ops. 0176077a8 Hans Verkuil 2014-04-27 147 * @type_ops: The control type ops. 0996517cf Hans Verkuil 2010-08-01 148 * @id: The control ID. 0996517cf Hans Verkuil 2010-08-01 149 * @name: The control name. 0996517cf Hans Verkuil 2010-08-01 150 * @type: The control type. 0996517cf Hans Verkuil 2010-08-01 151 * @minimum: The control's minimum value. 0996517cf Hans Verkuil 2010-08-01 152 * @maximum: The control's maximum value. 0996517cf Hans Verkuil 2010-08-01 153 * @default_value: The control's default value. 0996517cf Hans Verkuil 2010-08-01 154 * @step: The control's step value for non-menu controls. 20d88eef6 Hans Verkuil 2014-06-12 155 * @elems: The number of elements in the N-dimensional array. d9a254715 Hans Verkuil 2014-06-12 156 * @elem_size: The size in bytes of the control. 20d88eef6 Hans Verkuil 2014-06-12 157 * @dims: The size of each dimension. 20d88eef6 Hans Verkuil 2014-06-12 158 * @nr_of_dims:The number of dimensions in @dims. 0996517cf Hans Verkuil 2010-08-01 159 * @menu_skip_mask: The control's skip mask for menu controls. This makes it 0996517cf Hans Verkuil 2010-08-01 160 * easy to skip menu items that are not valid. If bit X is set, 0996517cf Hans Verkuil 2010-08-01 161 * then menu item X is skipped. Of course, this only works for 0996517cf Hans Verkuil 2010-08-01 162 * menus with <= 32 menu items. There are no menus that come 0996517cf Hans Verkuil 2010-08-01 163 * close to that number, so this is OK. Should we ever need more, 0996517cf Hans Verkuil 2010-08-01 164 * then this will have to be extended to a u64 or a bit array. 0996517cf Hans Verkuil 2010-08-01 165 * @qmenu: A const char * array for all menu items. Array entries that are 0996517cf Hans Verkuil 2010-08-01 166 * empty strings ("") correspond to non-existing menu items (this 0996517cf Hans Verkuil 2010-08-01 167 * is in addition to the menu_skip_mask above). The last entry 0996517cf Hans Verkuil 2010-08-01 168 * must be NULL. 20139f185 Mauro Carvalho Chehab 2017-09-27 169 * Used only if the @type is %V4L2_CTRL_TYPE_MENU. 20139f185 Mauro Carvalho Chehab 2017-09-27 170 * @qmenu_int: A 64-bit integer array for with integer menu items. 20139f185 Mauro Carvalho Chehab 2017-09-27 171 * The size of array must be equal to the menu size, e. g.: 20139f185 Mauro Carvalho Chehab 2017-09-27 172 * :math:`ceil(\frac{maximum - minimum}{step}) + 1`. 20139f185 Mauro Carvalho Chehab 2017-09-27 173 * Used only if the @type is %V4L2_CTRL_TYPE_INTEGER_MENU. 0996517cf Hans Verkuil 2010-08-01 174 * @flags: The control's flags. 20139f185 Mauro Carvalho Chehab 2017-09-27 175 * @cur: Structure to store the current value. 20139f185 Mauro Carvalho Chehab 2017-09-27 176 * @cur.val: The control's current value, if the @type is represented via 20139f185 Mauro Carvalho Chehab 2017-09-27 177 * a u32 integer (see &enum v4l2_ctrl_type). 0996517cf Hans Verkuil 2010-08-01 178 * @val: The control's new s32 value. 0996517cf Hans Verkuil 2010-08-01 179 * @priv: The control's private pointer.
