Hi,
I would like to know how to add new function to a driver in Linux Framework?
For eg: In GPIO driver, there is gpio_chip structure defined.
static struct gpio_chip mygpio_chip = {
.label = "mygpio",
.owner = THIS_MODULE,
.direction_input = mygpio_direction_input,
.get = mygpio_get,
.direction_output = mygpio_direction_output,
.set = mygpio_set,
.to_irq = mygpio_to_irq,
};
If i want to add *mygpio_pulldown* or *mygpio_altfunc* to support few more
gpio functionalities, how and where can i add these functions in the
structure?
Any suggestions on this will be appreciated.
Thanks in advance,
Asha
