Add the ops for GPIO driver set_dir_flags() to set the dir flags. The user can update the direction and configuration of each GPIO with a only call to dm_gpio_set_dir_flags() or dm_gpio_set_dir() and respecting the configuration provided by device tree (saved in desc->flags). When these optional ops are absent, the gpio uclass use the mandatory ops (direction_output, direction_input, get_value) and desc->flags to manage only the main dir flags: - GPIOD_IS_IN - GPIOD_IS_OUT - GPIOD_IS_OUT_ACTIVE - GPIOD_ACTIVE_LOW Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com> Reviewed-by: Simon Glass <sjg@chromium.org> |
