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;
         unsigned int clustered_irq;
         unsigned int clustered_irq_flags;
         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

       clustered_irq
           may be specified if interrupts of all row/column GPIOs are bundled to one single irq

       clustered_irq_flags
           flags that are needed for the clustered irq

       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.
