Re: [PATCH] gpio: mxs: implement get_direction callback

Hello.

...

quoted

struct mctrl_gpios *mctrl_gpio_init(struct device *dev, unsigned int
idx, int *irqs)

What is idx about? I see it already in the mctrl_gpio API, but there is
no documentation about how it's used. Is it always 0?

This could be used for drivers with several UARTs, which registered at once.
