Detailed Description

struct matrix_keypad_platform_data - platform-dependent keypad data : pointer to &matrix_keymap_data : pointer to array of gpio numbers representing rows : pointer to array of gpio numbers reporesenting colums : actual number of row gpios used by device : actual number of col gpios used by device : delay, measured in microseconds, that is needed before we can keypad after activating column gpio : debounce interval in milliseconds : may be specified if interrupts of all row/column GPIOs are bundled to one single irq : flags that are needed for the clustered irq : gpio polarity : controls whether the device should be set up as wakeup source : disable key autorepeat

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