3. 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
