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. Signed-off-by: Timur Tabi <timur@codeaurora.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org> |
