NAME¶
struct_matrix_keypad_platform_data - platform-dependent keypad dataSYNOPSIS¶
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_datapointer 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
