OK, if we were to do this, is there a way to build a static platform data with a
gpio descriptor ?
Ie. can I write something like :
struct generic_phy_pdata {
struct gpio_desc *reset_gpio;
};
And in machine code :
static struct generic_phy_pdata usb_phy __initdata {
.reset_gpio = XXX(19),
};
What should "XXX" be like to describe reset_gpio as a ACTIVE_HIGH gpio number 19
?
Cheers.
