Bug Description

On QDF2400 systems (ACPI-based), the kernel currently assumes all GPIOs from the qcom/pinctrl driver are configured for input. However, UEFI may have configured them for output. An upstream fix addresses this by adding a get_direction function:

    pinctrl: qcom: add get_direction function

    The get_direction callback function allows gpiolib to know the current
    direction (input vs output) for a given GPIO.

    This is particularly useful on ACPI systems, where the GPIOs are
    configured only by firmware (typically UEFI), so the only way to
    know the initial values to query the hardware directly. Without
    this function, gpiolib thinks that all GPIOs are configured for
    input.
