The GPIO list is very long in many cases and most of them are not used. By default, show only the GPIOs that are in use, and provide a flag to show all of them. This makes the 'gpio status' command much more pleasant. In order to do this, driver model now exposes a method for obtaining the 'function' of a GPIO, which describes whether it is an input or output, for example. Implementation of this method is optional. Signed-off-by: Simon Glass <sjg@chromium.org> |
