* @absmin: minimum values for events coming from absolute axes
* @absfuzz: describes noisiness for axes
* @absflat: size of the center flat position (used by joydev)
+ * @absres: resolution used for events coming form absolute axes
* @open: this method is called when the very first user calls
* input_open_device(). The driver must prepare the device
* to start generating events (start polling thread,
* @col_scan_delay_us: delay, measured in microseconds, that is
* needed before we can keypad after activating column gpio
* @debounce_ms: debounce interval in milliseconds
+ * @active_low: gpio polarity
+ * @wakeup: controls whether the device should be set up as wakeup
+ * source
*
* This structure represents platform-specific data that use used by
* matrix_keypad driver to perform proper initialization.
