Re: [RFC] GPIO API changes

Tomasz Bursztyka

Hi Vinicius,

Another issue of the current API is the confusion caused by
'gpio_port_enable_callback()' and 'gpio_pin_enable_callback()'.

With the changes proposed later in this thread, you could have a
unified call:
'gpio_enable_callback(struct device *port, uint32_t pinmask)' (or something like it)
gpio_port_callback() make the callback called, whatever pins is
triggering the interrupt and enabled or not (callback wise).
So they are different (documentation could be better though)

gpio_dw.c implementation is awkward however: I don't think it should by
default enable the int on pin 0.
