I have been going through some of the device tree files and I haven't come across way to represent a GPIO independent of a specific device, is it possible to do so using DT? How would I specify such a GPIO? I am working on MX28 (MXS for linux) based platform but if there are some other platforms already doing that would appreciate pointer to that dt file. -Subodh
