Hi.

I'm in the process of updating Zephyr from v2.3.0 to v2.4.0-rc1 and I've seen an unexpected change.

I have a custom board, and in the pinmux initialization I'm using the GPIO API to set some pins that need early initialization:

static int pinmux_stm32_init(const struct device *port)
{
    ARG_UNUSED(port);
    stm32_setup_pins(pinconf, ARRAY_SIZE(pinconf));

    const struct device *porti = device_get_binding("GPIOI");
    gpio_pin_configure(porti, 11, GPIO_OUTPUT_HIGH);
    gpio_pin_configure(porti, 12, GPIO_OUTPUT_HIGH);

    return 0;
}

This works with v2.3.0.
With v2.4.0-rc1 it builds without warnings, but when I try to run it on target it crashes during initialization.

During my debugging I've found that the GPIO API is in fact initialized _after_ the pinmux initialization, so that might be an issue.

Questions:
1.  Is this supposed to work? (using GPIO API from within pinmux_stm32_init())
2.  If not, what is the proper way of setting a pin high or low at this stage of the initialization sequence? stm32_setup_pins() only sets pin configurations, not actual pin value. (I can of course write directly to GPIO registers, but there's gotta be a better way)

Thanks,
Helge
