This can provide information about board features and the revision. Add a function that turns a list of GPIOs into an integer by assigning each GPIO to a single bit.

dm: gpio: Enhance gpio command to show only active GPIOs 2014-09-01T05:21:06+00:00 Simon Glass sjg@chromium.org 2014-08-11T15:23:52+00:00 89e6405425c7b52fd1330c61b6f5526612b87516 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>
