## 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.
