The i.MX6q sabrelite platform equips an egalax touchscreen controller, and this platform already transfered to GENERIC_GPIO framework, to support this driver, we use a more generic way to get gpio. Add a return value checking for waking up the controller in the probe function, this guarantee only a workable device can pass init. [dmitry.torokhov@gmail.com: Make driver depend on CONFIG_OF as it is now required.] Acked-by Zhang Jiejing Reviewed-by: Shawn Guo Signed-off-by: Hui Wang Signed-off-by: Dmitry Torokhov the eGalax driver now requires OF. For us this is a regression because we do not have OF: https://bugs.tizen.org/jira/browse/TIVI-740 -- Best Regards, Artem Bityutskiy
