Currently gpio-hog doesn't work on gpio-mt7621 driver. On further debugging, I noticed that set/clear register on this controller only works on output pins. We need to setup pin direction before writing values in bgpio_dir_out for a correct gpio-hog behavior. This patchset introduces a new flag BGPIOF_NO_SET_ON_INPUT for these kind of controller and set this flag for gpio-mt7621.
