MATRIX_KEYPAD(9) 					  Input Subsystem					   STRUCT MATRIX_KEYPAD(9)

NAME
       struct_matrix_keypad_platform_data - platform-dependent keypad data

SYNOPSIS
       struct matrix_keypad_platform_data {
	 const struct matrix_keymap_data * keymap_data;
	 const unsigned int * row_gpios;
	 const unsigned int * col_gpios;
	 unsigned int num_row_gpios;
	 unsigned int num_col_gpios;
	 unsigned int col_scan_delay_us;
	 unsigned int debounce_ms;
	 bool active_low;
	 bool wakeup;
	 bool no_autorepeat;
       };

MEMBERS
       keymap_data
	   pointer to matrix_keymap_data

       row_gpios
	   pointer to array of gpio numbers representing rows

       col_gpios
	   pointer to array of gpio numbers reporesenting colums

       num_row_gpios
	   actual number of row gpios used by device

       num_col_gpios
	   actual number of col gpios used by device

       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

       no_autorepeat
	   disable key autorepeat

DESCRIPTION
       This structure represents platform-specific data that use used by matrix_keypad driver to perform proper initialization.
